Thanks for fixing my mistake

Hi, thanks for fixing my accidental mistake on removing the Category:Megathrust earthquakes from the Megathrust earthquake article, I was actually intending to do that for another article that didn't belong in the category and accidentally did so for the article.

Passive Margins: Brazilian Margin

Hi Mikenorton, I didn't add the Brazilian Margin to the list I think I just reformatted the list when I added other entries. I think you are right that it would be more correct to just classify the south part of this margin as volcanic i.e. from where the SDRs are visible (South of -20Deg)? The paper 'South Atlantic volcanic margins' Gladczenko et al., (1997) in the Geological Society of London Journal has a good map on Figure 1. If you don't have access to this paper I can send you a copy. Alewisp14 (talk)

On formatting M

Regarding the symbol M used for earthquake Magnitude: do we have any notions of best practice on how it should be formatted? (E.g., italic or straight, spaced or closed-up, ??) Might there be any interest in having a template to handle the details? ~ J. Johnson (JJ) (talk) 00:26, 12 April 2016 (UTC)

Mesozoic

Hi, Mike Norton -- I just wondered what you thought of the recent edits to Mesozoic: this and the one right before it. I don't think "ca." is needed for such large numbers, do you? Also, the use of "prelude" as a verb is quite unusual:

• preludes to the lush Jurassic Period.

Does that sound right to you?  – Corinne (talk) 03:38, 15 April 2016 (UTC)

Hi Corinne, I've removed the "ca."s but added "roughly" or "about' as the numbers that divide the subdivisions are not as precise as quoted by the ICS. I also changed "preludes" to "precedes" and removed the older "lush" bit. Those edits overall improved things I think. Mikenorton (talk) 09:04, 15 April 2016 (UTC)

It's much better now. Thanks. I'm wondering whether "roughly" shouldn't be right before the first number in the ranges. If it is a synonym of "about", or "approximately", and you've put "about" right before the first number in another range, then shouldn't it be in the same place? "Ranges roughly from X to Y" or "ranges from roughly X to Y"? I'm on the fence, but I think the second one sounds more colloquial.  – Corinne (talk) 15:20, 15 April 2016 (UTC)

Hello

Hello, I have some information about speleologists who investigated Kruber Cave in 60s. You see, the thing is that 'Krubera' wrong name. Is correctly Kruber Cave (see Alexander Kruber). Krubera Cave is Russian form (see Пещера Крубера [Peshera (cave) krubera) — Preceding unsigned comment added by 94.240.206.224 (talk) 14:57, 25 April 2016 (UTC)

You should raise this at the article talk page - Talk:Krubera Cave. I do note however, that most of the english language sources use the spelling currently used in the article name. We can only go by the sources. Mikenorton (talk) 23:30, 25 April 2016 (UTC)

Answer to a question in which respect is peridotite metamorphic

Metamorphic processes involed in peridotite formation are

• partial melting
• phase transitions (garnet to spinel, spinel to plagioclase)
• high temperature deformation (very important!These rocks have metamorphic texture). Pioneering work is done by Nicolas, French professor in late 70tie,s I think, I will add reference later.
• and many others I can think later

These methamorphic processes occur in earth mantle. The most peridotite exposed on Earth surface are of the mantle origin.

The rocks of earth’s mantle which are metamorphosed have been igneous rocks form by other igneous processes, from magma oceans in early earth history. I will try to expand the peridotite wiki in this respect if I have enough time. It is kind of priority, although I have other priorities... Obradow (talk) 16:04, 25 May 2016 (UTC)

OK, thanks Obradow, I understand now - I have a copy of Nicolas and Poirier (Crystalline plasticity and solid state flow in metamorphic rocks) on my bookshelf. The problem as I see it with calling it a metamorphic rock is that in most cases the peridotites that we see at the surface are from the mantle lithosphere. Although they are clearly deformed, tectonites I would call them, they don't have a changed mineralogy. Some would call them metamorphic, but I'm not so sure, although they can clearly be metamorphosed, that still makes them a metamorphosed igneous rock, rather than primarily a metamorphic rock. If you have a good source that describes them as metamorphic, then fair enough. Mikenorton (talk) 20:48, 25 May 2016 (UTC)

Hey THANK you Mikenorton for asking interesting question! Lets do following. Lets find the definition of metamorphic rocks. Wiki has to offer : Metamorphic rocks arise from the transformation of existing rock types, in a process called metamorphism, which means "change in form".

Textbook example states that any methamorphism includs all changes that affect rocks as resalt of chnages in pressure, temerature or composition of fluids in rock. It is then further stated that this occurs in sedimentary, igneous and even former metamorphic rocks. So strictly speaking mantle peridotites are mehamorphic rocks. There must be textbooks with even more clear definition.

Well the upper mantle peridoties are clearly special. Maybe they should be new division of rocks of rocks on planet earth : Earth's Core rocks, Earth's Mantle rocks, and Earth's crust rocks. (: Then peridotites would be even more important (: Their origin is unique in the sense that mantle was formed in earth early history (please somebody help, I know I read that somewhere), Earth was liquid at one point (please somebody expand this), after separation of core, earth mantle than crystallised, after that, it did changed it composition, texture by mehamorphic melting processes, this is how oceanic and partly continental crust is formed. If I get time I would like to learn about this and write what I learned. Just as teaser you can think about mantle peridotites as some previous peridotite which lost melt to create earth's crust.Obradow (talk) 21:53, 25 May 2016 (UTC)

I've reverted User:Obradow's edit in the Peridotite article about peridotite being a metamorphic rock. I've explained why, and offered an invitation for comment, at Talk:Peridotite#Igneous or metamorphic rock. GeoWriter (talk) 21:30, 27 May 2016 (UTC)

That sounds like a good plan, thanks. Mikenorton (talk) 21:36, 27 May 2016 (UTC)

Primary School

Perhaps you can help me about the categories...

I inherited of the Primary School project, which aims at improving a selection of articles considered relevant to Primary Education. As part of this project, I need to follow up do quality assessment, hence my adding the WikiProject to the talk pages of those articles (slightly over 200).

But the WikiProject Primary School was declared as a sub-project of South Africa WikiProject... so the problem I have is that I want to actually put the Primary School Project in the talk page to follow up quality, but not really the South Africa WikiProject. But I have no idea how to do it. I tried to find solution to only display one but not the other, but I could not find out how to do it. Practically, I do not even really care if the PP Projects is visible on the talk page. I only need to tag the pages so I can follow them for the quality assessement.

Do you have any idea how to do that ? Can you help or suggest directions ?

My alternative is to entirely remove the Primary School Project from the South Africa fatherhood... but am not sure if that is ok to do that and will obviously takes me a huge amount of time to fix everything. Any idea ?

Anthere (talk)

My apologies first of all for messing up my edit summary - when I referred to categories I meant WikiProjects (WPs) - that's what I get for trying to fit in a quick edit during my my lunch hour. To add a WP to an article it really needs to belong there, or we can end up with tens to hundreds for an article which would not be appropriate. I'm afraid that I don't know much about sub-projects, just the two that I'm involved in, WP Geology and WP Earthquakes, which don't, as far as I'm aware have, have subprojects. A good place to ask might be at the talk page of Wikipedia:WikiProject Council/Guide, but I see that you already know about that. Mikenorton (talk) 17:36, 6 July 2016 (UTC)

Hi JJ, I've already spent hours looking at "natural time" references and failed to come to any definite conclusions other than we're a little early in the history of the approach to be sure about anything. I will try to come up with something at the Rfc. Mikenorton (talk) 10:43, 10 July 2016 (UTC)

Thanks. Yeah, it is rather mind-boggling. (Don't get sucked down the drain!!) Even though I am not competent with large swaths of physics and mathematical analysis, yet I feel that my own failed attempts to grapple with any substance in those articles is less a reflection on my competence (or lack of) than on a lack of substance to grapple. That kind of stuff seems to be a counter-demonstration of the old saying that "you can't shine s**t". ~ J. Johnson (JJ) (talk) 23:14, 11 July 2016 (UTC)

Kaolin Deposits of Charentes Basin, France

Hello again, The article Kaolin Deposits of Charentes Basin, France has been tagged for various problems and would benefit from a geologist's attention. Please have a look if you have time.--Johnsoniensis (talk) 08:41, 31 July 2016 (UTC)

Hi, I've begun to take a look, but not sure how much time I can spend on it. I see that the original creator of the article is probably M.Koneshloo, who wrote the paper (with J-P Chiles) in the 'Further Reading' section - whole sections are verbatim and I'm not quite sure how to handle that.

Bowland Shale

Hi Mike - you tweaked this unit where mentioned in the Geology of Lancashire article that I've been editing (rather bit by bit!). I'd thought to include the former name (introduced as 'older texts') so as to explain the occurrence in literature of the name in different forms - did I get it wrong? cheers Geopersona (talk) 20:26, 6 August 2016 (UTC)

No not at all, I've adjusted it to link to the earlier mention of the unit and restored the 'Group'. More haste, less speed as they say. I noticed that the Bowland Shale Formation link in your new Trawden Limestone Group article was red, and thought that I should make a start on that one, seeing as there's so much interest in its potential exploitation for Shale Gas. I should be able to expand it over the next few days. Mikenorton (talk) 20:46, 6 August 2016 (UTC)

On the magnitude of Italy's quake

Hi, out of curiosity, I went to dig deeper into how the magnitudes are computed, and in particular which stations are used. You can find the complete data from the two agencies in XML format: INGV and USGS, and here you can find the meanings of the networkCode attribute of each station's measurement. With a couple of grep, sed and uniq on linux command line, it seems indeed that USGS only used a subset of the Italian stations and based most of its findings on US and Canada based stations. Also, it is not clear to me how the two agencies computed the error on their estimates. USGS quotes errors more than an order of magnitude smaller than INGV, which, as a physicist, sounds a bit fishy. I thought I would share these few observations with you.--Japs 88 (talk) 13:21, 26 August 2016 (UTC)

The USGS uses several different ways of calculating magnitude, even within moment magnitude - they quote Mwb, Mww, Mwp, Mwc, Mwr and so on. The magnitude that they quote for the Italian earthquake is a Mwp (for an explanation of what all these version of Mw are see here). I imagine that the quoted error is just the error inherent in that particular methodology, rather than the uncertainty regarding the actual total energy release of the earthquake, which is the intent of the moment magnitude scale. The bigger the earthquake, the less it matters that you have local station coverage, but for M6 it probably makes a bit of a difference. The USGS also quote magnitude estimates with each of the moment tensors, these give Mww, Mwc, Mwb & Mwr values of 6.2, 6.2, 6.1 & 6.1 and a wider range of hypocentral depths. It doesn't help us that there is normally no single magnitude estimate for an event - people still argue about the magnitudes for the 1960 Chile, 2004 Indian Ocean and 2011 Japan earthquakes. It would be interesting to know which approach INGV use to calculate their estimate, but it probably doesn't matter as I think that using the INGV estimate is the way to go, with a discussion of other estimates in the text (as we currently have it). These different estimates are neither right nor wrong, but having a "preferred" option is perfectly fine I think. Mikenorton (talk) 16:01, 26 August 2016 (UTC)

Thank you for your explanations. Because of all this misunderstanding, I'm going to write to the authors of the INGV analysis and ask them if they can write a blog post about it in their institutional pages. It would be useful to have a reference for cases like these. For the USGS uncertainty, I completely agree with you that the it is statistical only, and doesn't account for systematics. In the meanwhile the page has been reverted to 6.2 ± 0.0something, but I can't be bothered to keep discussing this issue, and I'll just let the US-centric views prevail. Thanks again for sharing your point of view with me.--Japs 88 (talk) 08:23, 27 August 2016 (UTC)

The 48 seconds was "very fast severe constant shaking, knocking over walls etc etc...", not shaking as you described it You interview "anyone" that lives in Sylmar and was awake or semi-awake during the earthquake they will all agree. I lived in Sylmar. If the edit is not done within the next 20 years or so, the accuracy of this earthquake will be lost forever. I am people that lived in Sylmar are the best source of information.

List of earthquakes in New Zealand

Hi, I hope this message finds you well. There are many lists that are lacking, but this one was just consolidated and it could use a proper tectonic setting section. You know, something that readers can really sink their teeth into. I'm sure there are other obligations or tasks to attend to, so just throw this one on the back burner as something to maybe tackle one day. It seems like there would be quite a bit to cover, but I was thinking of one or two paragraphs that could be the first primary section. Dawnseeker2000 21:12, 24 November 2016 (UTC)

Hi Dawnseeker2000, that's something that I should be able to do, although I've been having one of my quieter periods on Wikipedia recently.

Lake Tauca

Hi -- I saw from your userpage that you're a geologist, and was hoping you would have time to give an opinion on the Lake Tauca article. As you'll see on the talk page, the main editor there asked me what it would take to bring the article up to featured quality. There are a lot of papers cited, but I think the main problem is that there is no secondary source summarizing and synthesizing the papers into an overview. I don't think it's suitable as a Wikipedia article as it stands because it's simply a grab-bag of data from all the different papers. If no secondary source can be found, I think it'll have to be cut, or at best reduced to little more than a set of tables of data from the various papers. If you have a moment, I'd really appreciate your assessment. Thanks -- Mike Christie (talk - contribs - library) 13:51, 27 December 2016 (UTC)

Earthquake casualty estimation

Hi! I couldn't see how to mention this at the Earthquake portal (it seems rather inactive), but perhaps you could handle this? At any rate, User:MaxWyss – who is an expert on earthquakes, but not so much on WP – has been working on Earthquake casualty estimation, and has some issues regarding the article's title and "low" importance. I don't believe I am expert enough to advise him much on those (and having worked with him before I may be a bit biased in his favor). So I'd like to find someone who will work with him on that stuff. Perhaps get more page watchers. Any ideas? ~ J. Johnson (JJ) (talk) 22:38, 16 February 2017 (UTC)

Concern over an editor

Hi Mike. Just to let you know, I am writing to the admin people re a certain editors total domination of the HF in the UK page.

This is not what Wikipedia is for. If you wish to make sensible comment about this please do, including my editing.

Why you did that?

Modern hippo can obtain weigths of 4500kg and is 5m long at most, the Hippopotamus gorgops is bigger on average and not "much larger", also in page in List of largest mammals https://en.wikipedia.org/wiki/List_of_largest_mammals is saying "The largest species in terms of weight is the hippopotamus (Hippopotamus amphibius), native to the rivers of sub-Saharan Africa. They can attain a size of 4,500 kg (9,900 lb), 4.8 m (16 ft) long and 1.66 m (5.4 ft) tall.[3] Prehistoric hippos such as H. gorgops and H. antiquus RIVALED or exceeded the modern species as the largest members of the family and order to ever exist." — Preceding unsigned comment added by 109.48.210.235 (talk) 17:22, 30 January 2018 (UTC)

Only exceptionally do hippos (H. amphibius) weigh more than 3200 kg and they are normally less than 2500 kg according to the sources that I've just checked, which makes them considerably smaller than the "average" H. gorgops, although I struggle to find a good source for the 3900 kg figure used in our article. To make sense I think that we should be comparing the average H. gorgops with the average H. amphibius, with the former generally being considerably bigger than the latter. Also it does you no favours at all if you don't include an edit summary to explain what you are doing - such edits are often straightforward vandalism. Finally we don't use other Wikipedia articles as references. I think that we could go with just saying "larger", which is a change that I will make. Mikenorton (talk) 18:06, 30 January 2018 (UTC)

Many sources like this http://animaldiversity.org/accounts/Hippopotamus_amphibius/ show that the largest modern hippo was in fact 4500kg, so the biggest ones could be bigger than the H.gorgops, but yes on average looks like the gorgops was bigger, but we don't know if 3900kg is the average or the biggest individual found (fossilized of course)

From what I can make out, the 4500 kg weight is exceptional, with 3200 the normal maximum and less than 2000 the average. If I was sure that 3900 was a good average estimate for H.gorgops (because it must of course be an estimate) then I would be happy to change it back to "much larger". Mikenorton (talk) 20:30, 30 January 2018 (UTC)

I don't think the 3900kg is average, I believe is "up to 3900kg", this is the only wikipedia that was saying "much larger", the H.Antiquus for example was "Similar in size and form to Hippopotamus gorgops, H. antiquus on average was larger than the modern common hippopotamus ". "On average". So the 3900kg is probably the biggest size know. It took me a while but I found this: http://i.imgur.com/y12xkOd.jpg Keep in mind that is the largest know skull, so this is where the 3900kg probably come from. 13:14, 31 January 2018 (UTC)

Another find: https://app.box.com/s/8ccpfvbaai5qwta8vb101qcnwaoef9z4

With this quote: "University of Cambridge and at the Natural HistoryMuseum of London, range from the size of average modern hippopotamuses to really massive individuals. The latter are only~10% smaller, in linear sizes, andonly some 7% lighter than the heaviest Collecurti indi-viduals" — Preceding unsigned comment added by 109.48.210.235 (talk) 13:33, 31 January 2018 (UTC)

I knew that was going to happen

And had a draft of a response to your proposal on the list's talk page, saying to just go ahead and do it, because we need to start driving this train and not let the passengers dictate which direction we're going and when. I'll post what I had, and thanks for taking the initiative; that one was going to be tough one. Dawnseeker2000 17:33, 14 March 2018 (UTC)

I'm not entirely surprised, but I will continue trying to get a discussion going. Mikenorton (talk) 17:35, 14 March 2018 (UTC)

I've been thinking about this for a while: I'd like to modify the notability guideline to include some details that address minimum qualifications for list entries. I've been linking to it the list footers, so maybe now is the time to actually write something. Had mentioned earlier that either you or J. Johnson could tackle it (it was kind of your thing, but he's quite good with policy-type content), but I guess I could take a stab at it too. A few sentences can go a long way. Dawnseeker2000 06:08, 16 March 2018 (UTC)

I've been reading further about standalone lists and found " one of the functions of many lists on Wikipedia is providing an avenue for the retention of encyclopedic information that does not warrant separate articles, so common sense is required in establishing criteria for a list". I've tried to come up with a way to handle the non-notable events in list articles - starting with the British Isles one - see that talk page discussion. Mikenorton (talk) 10:48, 16 March 2018 (UTC)

Hippopotamus gorgops size

Hello, as you are the only one in this topic right now, what do you think about the size of these hippo? I really couldn't find any realiable source about the size, where the 4,3m, 2,1m and 3900kg figure come from? — Preceding unsigned comment added by 109.48.210.235 (talk) 14:00, 14 April 2018 (UTC)

They come from the cited source (Palmer 1999) - user:Anaxial (who added the citation nearly nine years ago) confirmed that a few days ago - here. Mikenorton (talk) 15:39, 14 April 2018 (UTC)

It may be, of course, that the published source is wrong - some degree of estimation will naturally have been involved, if nothing else - but that is what it says. Now, while I think it's reliable, it's also a pop science book, so if somebody finds a better source with a more accurate figure, that would be great. I had a quick look myself, and couldn't find one, but that doesn't mean there isn't one out there. Until it turns up though, we're stuck with what we can verify. Anaxial (talk) 17:02, 14 April 2018 (UTC)

Thanks, finally a good source, this makes sense now. But still there is a lack of studies about the size of this pre historic hippo, as I found somewhere in the internet some pics of bones of the Hippopotamus gorgops compared to the modern hippo, they were almost the same size, so I believe the 2,1m and 3900kg figure is exaggerated, but anyway I also have no proof. I also found this picture which maybe it's true http://i.imgur.com/y12xkOd.jpg — Preceding unsigned comment added by 109.48.210.235 (talk) 21:37, 14 April 2018 (UTC)

Blisworth Limestone Formation and Northampton Sand Formation mergers

It has come to my attention that the Blisworth Limestone and White Limestone Formation represent the same unit according to the BGS, with both the page for the Blisworth Limestone and the White Limestone saying that they are each others synonym. The fact that there are still two separate articles indicates some sort of error on BGS's end. There also isn't any indication of which name is more prevalent, so I am unsure how to proceed. It is also worth noting that there are three separate articles for the Northampton Sand Formation including Northampton Sand and the Northampton Sands, which need to be merged. Hemiauchenia (talk) 17:47, 30 July 2018 (UTC)

What it seems to be saying is that the two are lateral equivalents of each other. From White Limestone Formation, under Geographical Limits it says "The Stroud to Cirencester area, where it passes south-westwards into the Athelstan Oolite Formation, and north-eastward through Oxon and Bucks to the Brackley area, where it passes north and east into the Blisworth Limestone Formation.", with something similar on the Blisworth Limestone Formation page. So the following are all lateral stratigraphic equivalents (and maybe there are more if I followed through all the other formations): Blisworth Limestone Formation, White Limestone Formation, Athelstan Oolite Formation, the upper part of the Rutland Formation. As to the Northampton Sand Formation, there has been a lot of duplication in articles (two of them were created by the same editor), often related to fossil occurrences - not all palaeontologists are the best at checking the up to date formation names. I'll have a go at merging them. Mikenorton (talk) 18:17, 30 July 2018 (UTC)

The fact that BGS lists the Blisworth Limestone as a previous name of the White limestone formation is what threw me off. It makes more sense if both of those formations were split off the initial "White Limestone" (WLM) mentioned on the pages. I'll make sure to mention it in the articles Hemiauchenia (talk) 18:33, 30 July 2018 (UTC)

Looking better and a lot clearer now - this naming of units can be so confusing. After looking at the three Northampton sand articles, I propose redirecting Northampton Sands as it has virtually no content and merging Northampton Sand into the Northampton Sand Formation article. Mikenorton (talk) 23:33, 30 July 2018 (UTC)

That's what I was thinking also. A merger between the Cornbrash Formation and Cornbrash articles was proposed back in February by User:GeoWriter but it seems they didn't get around to it. So I will give that a go Hemiauchenia (talk) 15:29, 31 July 2018 (UTC)

An odd Request...

Wikivoyage is a user generated travel guide.

You seem to be an expert on some geological matters so was wondering if you could consider adding some "geological tourism" information to relevant Wikivoyage articles? Or even perhaps creating an Itineraries that was a Geologist's tour of Great Britain as that's something that Wikivoyage doesn't yet have...

It would also be appreciated if you could ask your fellow WikiProject Geology contributors if they would also be interested in contributing 'geological' tourism content on Wikivoyage..

I will also note that Wikivoyage doesn't necessarily have a guide on Mineral curiosities to cover things like crystals, gems and other rock related tourism... Hmmm...

Flood Geology

You have exhibited some interest in the article on Flood Geology. You probably already know that the article is not about floods or geology, or surface-water hydrology, or sedimentary geology, so even though you may not see the need for an about template at the top of the article, because the term "Flood Geology" includes the terms for the separate topics of floods and geology, it is expedient for the distinction to be made at the top of the article so that less-informed readers such as myself are not confused by the homonymous terms. This is noted on the talk page, which I encourage you to participate in before reverting edits.Sotuman (talk) 21:32, 18 February 2019 (UTC)

(talk page gnome) @Sotuman: Please see WP:BRD (consensus is expected before restoring edits). There is no need to dispute with individual editors as the main discussion should occur at the article's talk page. —PaleoNeonate – 03:18, 19 February 2019 (UTC)

My comment was in relation to this edit which restored the material without consensus. —PaleoNeonate – 05:40, 19 February 2019 (UTC)

@PaleoNeonate:My comment was in relation to the lackluster discussion from other users on that article. All they say is "concensus, concensus" but there is no effort at discussion, only "oh it looks like you're pushing a creationist POV, therefore we will ignore you," but this is incorrect. The whole flood geology article is a big, ugly straw man that serves no purpose on Wikipedia. If it must stay as-is, like a boil on the face, then it should point to actual floods and geology, in the interest of salvaging some dignity for Wikipedia.

Drawing and uploading geological maps

Hi Mike

You seem to know what you're doing in drawing and uploading geological maps; I'm just embarking on that with two creations - now incorporated at Geology of Monmouthshire and Geology of Mull. I'd always shied away from images in the past as the copyright issues seemed problematic but I'm presuming with appropriate text we're fine with BGS's OpenGovernment mapping. I'm puzzled as to why my uploaded Mons geology png looks washed out because the original doesn't - no such problem though with the Mull map. Any tips you can give re that or anything else w.r.t. geol map uploads would be appreciated. All best wishes as ever Geopersona (talk) 10:53, 7 March 2020 (UTC)

Sorry for the delay in replying, I've been in California and only got back last week and now with all this COVID-19 stuff going on it's somewhat distracted me.

In that process, I discovered three irregularities that I'd appreciate your input on.

• There's a Category:M V in the template that isn't in the documentation and wasn't in your proposed renaming. The code refers to "Vanek mag."
• Somehow, bLg and n were directed to the same category, Category:Articles using MbLg magnitude scale. Category:M N was not in your list. The code talks about "blg" as "mbLg wave mag." and "n" as "Nuttli (mbLg wave) mag."
• Towards the end, there appears to be a "test" entry directed to Category:M test, which can be accessed using "x" as the input. I don't know if this has to be renamed.

As far as I've seen, I think that the template fixes that I did have cleaned up the redlinks, but if you catch more let me know. Thanks, bibliomaniac15 21:53, 30 May 2020 (UTC)

@Bibliomaniac15: Thanks for sorting those out. The M_N and M_bLg magnitudes are identical and it was the only merge that I suggested.

As to Mv, that seems to be a variety of Ms, although it doesn't seem to be used anywhere on the project that I've seen. I imagine that M test was used in the early stages of development, although I don't actually know how. I'll contact the originator of these categories to check whether they're still needed. Cheers,Mikenorton (talk) 12:38, 31 May 2020 (UTC)

Great, thanks for everything. Let me know if you need more help. Yesterday I also went over the documentation subpage to fix things up too; hopefully I caught everything there too. bibliomaniac15 18:12, 31 May 2020 (UTC)

@Bibliomaniac15: M_V is used in seismological literature, particularly European of a certain age, and some catalogues, so worth having. That could be changed to Category:Articles using MV magnitude scale. It still needs to be added to the template as an option, but that template and the relevant article has been under slow development for a few years now and still not quite complete - partly because we keep on finding new magnitude identifiers in the literature - for instance we still have to work out what to do with the Italian INGV's M_e, which is not the same as M_e, but is used in several articles. The test one can go - he'll recreate it if and when he needs it. Mikenorton (talk) 08:35, 1 June 2020 (UTC)

Ok, great. Category:M V was never created in the first place, so there wasn't anything to move. I switched the name on the template, but beyond that, the category is open for creation if/when it's needed. bibliomaniac15 18:36, 1 June 2020 (UTC)

2020 Alaska earthquake expertise needed

I started a draft for the 2020 Alaska earthquake, and I need your geologic expertise on the subject. I realize that your knowledge on these kinds of things far exceed mine, and it would be very valuable to the community if your summation of the earthquake was added to the "Geology" section of the article.

Many thanks, GyozaDumpling (talk) 12:08, 22 July 2020 (UTC)

(talk page stalker) Please don't publish that draft to mainspace. There's no real value in writing about something with no impact on people, places, and things. Dawnseeker2000 12:36, 22 July 2020 (UTC)

The draft was published prior to your input, I apologize. Would you recommend I begin the deletion process? GyozaDumpling (talk) 14:41, 22 July 2020 (UTC)

No deletion would be required, it could be redirected to the relevant month in the List of earthquakes in 2020 article, as was done with the 2020 Kuril Islands earthquake article. The entry in the list article should be able to include all the important information about the earthquake. Mikenorton (talk) 20:32, 22 July 2020 (UTC)

I've redirected the article to the "July" section of List of earthquakes in 2020. Thanks for your suggestion. GyozaDumpling (talk) 20:53, 22 July 2020 (UTC)

I think that's the best outcome for now. If a lot more information turns up or numerous scientific papers are written, it can always be turned back into an article. Mikenorton (talk) 22:52, 22 July 2020 (UTC)

The article has been retrieved

Webecoolalasdair Notified me a few days ago that there is substantial notability for the 2020 Alaska Peninsula earthquake, so we both agreed to retrieve it from its blanked, redirected state. It would be great if you could help us redevelop this article with up-to-date research and info. Thanks, GyozaDumpling (talk) 19:47, 11 August 2020 (UTC)

Hello

I am a relatively new wikiperson. I'd like to introduce myself. My name is Alasdair, and am a university student pursuing a degree in Geology. I have a passion for understanding earthquakes. I have a little experience on here, and am working on several earthquake drafts at the moment. I was wondering how I can become a part of the earthquake community on here? I understand you are the head of the earthquakes wikiproject, so I thought it be best that I come here and ask. I would like to become a wikiperson the right way. Thanks. Webecoolalasdair (talk) 21:40, 9 August 2020 (UTC)

Hi Alasdair, to become part of the community, just start writing, whether it's a new article (those are more difficult and you need to be aware of things like the notability guidelines that affect earthquake articles, particularly WP:GNG and WP:EVENT), or an expansion of an existing article, there are many of those to choose from. It's not just recent earthquakes that articles are needed for - if they're notable someone will normally start an article - but historical ones that were damaging and caused many deaths are at least as important I think and many of those still lack articles.

Supercontinents

I fear I may have gotten a little testy on my edits here. Current supercontinents keep reappearing, and so does Zealandia as a minor supercontinent. But, durn it ... --Kent G. Budge (talk) 19:48, 31 October 2020 (UTC)

A minor supercontinent - that would be a continent then, or maybe a major microcontinent? The sooner that the list article is redirected the better, then there'll only be one article to fight over. Mikenorton (talk) 20:23, 31 October 2020 (UTC)

List articles make sense when there are many items in the list. Here it just encourages mischief, because there just aren't that many well-identified supercontinents in the geologic record. Only one at a time by any reasonable definition. --Kent G. Budge (talk) 20:26, 31 October 2020 (UTC)

Adjectives Issue

Earlier I made a edit adding Earthling to the adjective used to describe people from Earth and it was immediately reverted because it was claimed by Mikenorton that it was not a Adjective. My question is how is the use of earthly, terrestrial, terran, tellurian a Adjective while Earthlings are not? Earthy isn’t even used to describe inhabitants who live on earth but rather characteristic of quality’s of people who are from or associated with earth. Earthlings on the other hand is the main description used for people from earth and has been used as such since 1590.

I recall Chris Talbot (a 1986 paper of his on the topic) giving a talk about that fault at an annual tectonics/structural geology conference back in the mid-1980s. Fascinating set of endglacial faults, that must have created some sizeable earthquakes at the time. The Pärvie Fault certainly looks worthy of an article. Mikenorton (talk) 12:46, 2 March 2021 (UTC)

Reigate Stone

Hi @Mikenorton: I have written some text on Reigate Stone, which I have added to the Upper Greensand Formation article that you created. This may not be the best place for it, but I am not convinced that there is enough material for a new Reigate Stone article. Would you be able to take a quick look and let me know your thoughts please? (I am not a geologist or engineer, so this is not my area of expertise. My interest is primarily in the historical use of the stone.) Thanks and best wishes Mertbiol (talk) 12:11, 19 May 2021 (UTC)

Hi @Mertbiol:. I think that there is plenty there for a standalone article. I think that there is enough material out there, particularly from various "strategic stone studies" to create a section on "Use", including a summary of the Reigate Stone in Surrey, details about: the Green Glauconitic Sandstone of Devon, the Bonchurch and Ventnor Stone of the Isle of Wight, the Malmstone of West Sussex and Hampshire, the Potterne and Hurdcott Stone of Wiltshire, the Eastbourne Sandstone of East Sussex, the Shaftesbury Stone of Dorset and some information on both Kent and Bedfordshire. Mikenorton (talk) 15:20, 20 May 2021 (UTC)

Thanks @Mikenorton: Having read around a few other 'stone' articles (and slept on the comments I wrote yesterday), I think I now agree. I will split off the content on Reigate Stone into a new article. Thanks and best wishes Mertbiol (talk) 17:53, 20 May 2021 (UTC)

I look forward to seeing it. I'll concentrate on producing a "Use" section in the Upper Greensand article, now that I've found some sources. Mikenorton (talk) 20:42, 20 May 2021 (UTC)

Volcanoes in the UK

Hi Mike

I noticed you'd removed Brent Tor from the list. I've been troubled for some time at the growing list of 'volcanoes in the UK'. So many examples are only volcanoes in a rather tenuous way insofar as they represent the deeply eroded roots of volcanoes from way back. One of my concerns is that the geologically uninformed reader of Wikipedia (and there are many of those despite our best efforts) will conjure up pictures in their mind of gas, ash and lava spewing from the landforms which we see today. I've previously added some material in the introduction to try to dispel this notion but remain concerned. There is the question as to what constitutes a volcano - it cannot surely be a few traces of extrusive or intrusive igneous rock sometimes wholly disassociated from the original landform, can it? cheers Geopersona (talk) 06:51, 19 June 2021 (UTC)

I agree, the whole list is problematic. We really need a source (or sources) that provides a list of former volcanoes. An alternative might be a list of volcanic centres, as that might be something that we could find sources for. That would probably work for the Palaeogene but the older we go, the more difficult it becomes. In the Lake District the Borrowdale volcanics have several identifiable calderas and basins but elsewhere it's less clear. I'll open a discussion about inclusion criteria.

Strike-slip tectonics Article

Just came across the Strike-slip tectonics article when looking up "Riedel shear". Excellent and useful article (to which you've made major contributions). Thanks! Finney1234 (talk) 16:27, 20 August 2021 (UTC)

Question: "step over" is a little messy. It looks like "step-over" and "stepover" are acceptable geological alternatives which might be a little cleaner. Any thoughts? Finney1234 (talk) 16:33, 20 August 2021 (UTC)

Also: I don't know if you wrote the following sentence, but it is (IMHO) not very clear (a bit long and convoluted). Unfortunately, I'm not sure how to edit it because I'd worry about changing the intended meaning. The final phrase "until a throughgoing fault is formed" is the confusing part. Again, any thoughts? Finney1234 (talk) 19:50, 20 August 2021 (UTC)

"With further displacement, the Riedel fault segments will tend to become fully linked, often with the development of a further set of shears known as 'P shears', which are roughly symmetrical to the R shears relative to the overall shear direction, until a throughgoing fault is formed".

Hi Finney1234, I'll try to come up with an alternative. To explain the last part, the initial disconnected and en echelon R shears become connected by other shears, eventually forming a single connected fault zone - the term "throughgoing" indicates that the fault zone has become a single zone of faulting going through the whole affected block. Mikenorton (talk) 23:37, 20 August 2021 (UTC)

Mikenorton : OK, I made a change that I think matches your description and is more comprehensible. Leave it or change it as you see fit. Finney1234 (talk)

Afro-Laurasia

Hey you know that some people don't recognize afro-eurasia as a supercontinent Well I am not giving up because I have a idea That land bridge that once connected Russia to Alaska I think it's possible to bring back beringia by building dams and draining the water and the water covering up Beringia will be sent to the Arctic ocean and the Pacific ocean and with Beringia brought back not only would this help humans with climate change but it also means that Afro-eurasia is connected to the Americas Afro-eurasia + The Americas = Afro-Laurasia and a supercontinent is recognized if all or most of the Earth's landmass are together and Africa is connected to the middle East and Oceania is going to join millions of years later anyways.

Groningen gas field

Dear Mikenorton. I see you have written about the Groningen gas field in the past. I recently wrote a page about it on the Dutch Wikipedia which I translated to English (I am not a native English speaker, so wording is probably not perfect everywhere). I focused mostly on the social, political and historical aspect of the gas field, as I am not a geologist. I tried to add some information to what you already wrote in the past. However, I did not understand everything and had a hard time judging what to keep and how to keep it in a fluent manner. I was therefore wondering if you could check the Groningen_gas_field#Geology section. Maybe you spot errors, know what should be added or should have been kept from previous version.

VEI

Suggest you add to talk in article if you are actively checking for sources you yourself trust and reverting an article you are watching. Over to you. Obviously the steam component confuses issue wrt orginal definition VEI and subequent debate as to redefinition. No ash eruption column that has reached 35km has ever in history be assigned to a VTE less than 5 see - [1]. If the steam component was more than twice the ash component in volume the debate could go on for years on original definition of VEI. ChaseKiwi (talk) 14:40, 22 January 2022 (UTC)

I'm still waiting to see something definitive in a reliable source that allows us on wikipedia to add this as VEI=5, although its seems quite likely. Shane Cronin said that "early data suggested the eruption could measure as high as five on the volcanic explosivity index (VEI)", which is close but not enough to add it I reckon. Probably worth me starting a discussion on the eruption's page as you suggest. Mikenorton (talk) 15:45, 22 January 2022 (UTC)

I've tagged the volume quoted in the eruption article as the cited sources are contradictory - stating both "twice the size of Mount St Helens in 1980" and "up to 1 km³" - it can't be both. Mikenorton (talk) 16:00, 22 January 2022 (UTC)

Highlands Controversy

Thank you for taking an interest in Highlands controversy of Northwest Scotland. I had come across your editing on geological topics and wondered whether to consult you while this was still a draft but I chickened out.

Thanks for creating that article - it's an interesting bit of scientific history, obviously something I've heard about as an undergraduate and later, as my PhD supervisor Stan White was working on samples from Eriboll at that time. He later wrote his own version of the development of the thrust theory, particularly as it pertains to the coining of the word "mylonite", here, which you might find useful.

Took me long enough - I've made some changes to the "Tectonic setting" and "Future threat" sections, which I will address on the article talk page. Mostly I see few issues other than those that I've already dealt with in those edits. I'm a bit concerned about the fault map as it looks like it might be a "too faithful" copy of the original (and therefore a copyright infringement), but I don't have access to the source. If you do, I would be grateful for a copy of Bell et al. (2009) to allow me to check. Mikenorton (talk) 17:29, 7 December 2022 (UTC)

Thank you so much for helping with the article, the phrasing looks better now. I have downloaded a copy of Bell et al. (2009), however I am unsure as to how to best send it over to you. I could email it to you if that works best. SamBroGaming (talk) 19:37, 7 December 2022 (UTC)

That would be great, thanks. Mikenorton (talk) 19:39, 7 December 2022 (UTC)

Hello again. Apologies for the late reply, but I have been unable to locate your email address. Where would be the best location to send it to? SamBroGaming (talk) 04:11, 11 December 2022 (UTC)

Not a problem, you should be able to email me using the "Email this user" feature on this page under "tools". Mikenorton (talk) 11:03, 11 December 2022 (UTC)

Thanks for the email, the map is fine as far as copyright is concerned, but it lacks quite a bit, such as an explanation for all the fault names and the section lines are unnecessary here. I'll see if I can whip up an alternative map with a topographic background. Mikenorton (talk) 20:52, 11 December 2022 (UTC)

Why remove earthquakes that are "insignificant" although sources didn't specify if it's slight damage

On my edit summary here, I said that the source specifies cracks on plaster, but that does not refer to the December 15 event, but rather to the 3.1 event on November 23. Source didn't reveal what damage exactly was caused to the 20 buildings mentioned. We aren't sure if the damage did by the quake on December 15 was also the same as the one did by the November 23 event. So why won't we consider this as "significant"? Thanks! Filipinohere (talk) 03:51, 17 December 2022 (UTC)

@Filipinohere: The main reason for doubting the severity of the damage reports is that the same source mentions 9 reports of damage from an earlier tremor in November (slightly smaller magnitude) saying that they concerned "minor scratches on finishing elements (such as gypsum boards and plaster coats)" (google translate text). Presumably there is likely to be compensation from the mine owners, so even the slightest things will be mentioned. I will discuss this further on the article talk page. Mikenorton (talk) 11:31, 17 December 2022 (UTC)

Another thing, there is a similar instance in which you removed the quake in Italy due to "insignificant damages". Quite similar circumstances with the Poland quake (?). Source mentions that fallen plaster and broken windows were reported, as well as a 1.5 m (4 ft 11 in) high tsunami caused by the collapse of a ridge. So, by the way, does the Italy and Poland quakes are deleted from the list for similar reasons? And I noticed that there was a "new standard" for the criteria for the list. Filipinohere (talk) 03:44, 18 December 2022 (UTC)

It's not proper English

The length and width dimensions are expressed as characteristics of the Canyon, while the depth is not expressed that way--the Canyon "attains" the depth. The first two should be connected by "and"; the third should be preceded by "and." People need to get over this widespread phobia over using "and" too many times. Change it back. Rontrigger (talk) 08:22, 29 March 2023 (UTC)

I understand why you made the change, I just think that the original reads better, even if it's not "proper". My English language education, however, was definitely lacking, so I wouldn't claim to know what's right here. Mikenorton (talk) 08:56, 29 March 2023 (UTC)

Wytch Farm

Regarding Wytch Farm, many sources online claim it's the largest oil field in Europe (not just Western Europe). I wonder what's the truth?

2A00:23C7:69B1:501:D4E5:E92:CA89:C5B5 (talk) 19:43, 13 January 2024 (UTC)

Here are a few reliable sources Journal of Petroleum Geology, Energy Industry Review, Reuters for Patos-Marinza's claim, although there are sources that just say it is one of the largest. For Wytch Farm there are plenty that say it is the largest in western Europe specifically, UK onshore oil and gas, BBC, Bowman et al. 1993 (first sentence "The Wytch Farm Field is the largest onshore oilfield in Western Europe"). Don't rely on local press, they often get things wrong. I've tried to find a list of european oilfields by size, but no luck so far. Mikenorton (talk) 20:30, 13 January 2024 (UTC)

Oh thank you for that and the for the helpful tip! 2A00:23C7:69B1:501:D4E5:E92:CA89:C5B5 (talk) 20:37, 13 January 2024 (UTC)

ISC event links

Dear Mike,

I am Domenico Di Giacomo, senior seismologist with the International Seismological Centre (ISC, http://www.isc.ac.uk/about/staff/) and with this email I'd like to seek your help to address a problem that Wiki users will have in the near future. To explain the issue let's consider the ISC event link for the Dalbandin Earthquake (https://en.wikipedia.org/wiki/2011_Dalbandin_earthquake) where the ISC Event Bibliography link directs to http://isc-mirror.iris.washington.edu/cgi-bin/FormatBibprint.pl?evid=15938045. This link is actually from our mirror site hosted by colleagues in the US (it appears to me all links you kindly added use the mirror site instead of www.isc.ac.uk.). The same page is available at http://www.isc.ac.uk/cgi-bin/FormatBibprint.pl?evid=15938045, which is from our own website. Using the mirror site link is all right for the time being but the mirror site in the US will no longer be available within the coming months.

Thus, I wonder if it is possible for you to update the "root" of the URLs linking to ISC pages by replacing http://isc-mirror.iris.washington.edu/ with http://www.isc.ac.uk

Please bear in mind that I am new to Wikipedia as an editor role so I am not be aware of the best way to update content. I just thought that it would be best to touch base with you first and discuss both what's the best way to address this issue and possible way forwards.

With Kind Regards

Domenico Domenicodigiacomo (talk) 10:15, 26 January 2024 (UTC)

@Domenicodigiacomo: Dear Domenico, thanks very much for the heads-up. The link is introduced into earthquake articles by adding the event number to the earthquake infobox template. This was set up by an editor who is sadly no longer active, so I will have to seek help to find out exactly how the url is generated, so that it can be amended. I would just like to say how incredibly useful the online bibliography is when creating and updating earthquake articles.

Regards, Mikenorton (talk) 10:36, 26 January 2024 (UTC)

Let me know if I can help in any way, and thanks for the kind words Domenicodigiacomo (talk) 10:44, 26 January 2024 (UTC)

Thanks, I'll let you know how I get on. Mikenorton (talk) 11:11, 26 January 2024 (UTC)

@Domenicodigiacomo: well that was simpler than I was hoping - fortunately the people at the help desk are very helpful with that sort of thing. Now I just have to find the best way of updating all the links to individual earthquakes in the NOAA earthquake database that I haven't already fixed - no heads-up there, the links just stopped working one day, linkrot (as we call it) is a major issue here. - I found out how to do that, just 487 more links to update.

Given that you're a seismologist, which I am not, is there anything major that you've noticed with our earthquake articles that could be improved? Mikenorton (talk) 15:11, 26 January 2024 (UTC)

From the quick looks that I had so fat I think that the pages are good and informative. I don't have any particular suggestion at the moment, I will try to find the time to look at them more closely and come back to you if I think of anything Domenicodigiacomo (talk) 16:46, 26 January 2024 (UTC)

Thanks and please don't feel obligated. We have very few to no active geophysicists working on earthquake articles here and I sometimes feel a little exposed by my lack of any formal seismological training, particularly when I do things like write articles on supershear earthquakes. Mikenorton (talk) 20:20, 26 January 2024 (UTC)

Health update

To anyone looking in, I'm currently recovering following a pulmonary embolism a few days ago. I'm responding well to treatment but have little idea when I will be able to contribute again effectively. Mikenorton (talk) 16:06, 8 March 2024 (UTC)

Best to you brother. Your presence here makes this place tolerable! Dawnseeker2000 17:19, 8 March 2024 (UTC)

Thank you Dawnseeker2000, much appreciated. Mikenorton (talk) 20:48, 8 March 2024 (UTC)

Hope you get well soon. Ben MacDui 14:32, 9 March 2024 (UTC)

Thanks MacDui. Mikenorton (talk) 14:54, 10 March 2024 (UTC)

Sending you my best wishes and a speedy recovery, Mike Dora the Axe-plorer (explore) 15:54, 10 March 2024 (UTC)

I'd like to add my very best wishes here too, Mike. Geopersona (talk) 20:59, 10 March 2024 (UTC)

I hope you have a quick recovery, Mike. You are an integral member of the community and I appreciate your efforts. SamBroGaming (talk) 00:43, 11 March 2024 (UTC)

Thanks everyone. I'm back at home, but possibly on blood thinners for the rest of my life, which is nothing too terrible. I'm going to start trying to pick up my editing again but it will be slow to begin with because I'm profoundly weary much of the time. Mikenorton (talk) 13:25, 16 March 2024 (UTC)

So sorry to hear about the PE, Mike, but I hope your recovery is progressing smoothly. Sorry for the delayed response - I only check Wikipedia so often these days. Fondly, ceranthor 05:25, 15 April 2024 (UTC)

Further health update

I've just had one of the two planned procedures that I'd been waiting for. I am officially fully recovered from the pulmonary embolism, so just a few other things to get sorted. I'm back editing as normal, in fact it's been a useful distraction over the last two months - I've not created this many articles in a few years. Mikenorton (talk) 19:10, 1 July 2024 (UTC)

Eigg

I wonder if you could take a few minutes to look at the Geology section at Eigg? I have been attempting to improve the article and the current text sounds plausible but is largely unsourced. Ben MacDui 15:22, 27 July 2024 (UTC)

@Ben MacDui: The text was added by User:Geopersona, which means that it should be absolutely fine and checks out using the BGS geology viewer. I'll take a look anyway and possibly add some more citations, if that looks necessary, and maybe think about adding a map, which should be as quick to produce as they ever are. Mikenorton (talk) 21:31, 27 July 2024 (UTC)

@Ben MacDui: The map is done. Need to add a sentence about the Upper Cretaceous Strathaird Limestone Formation and some other minor additions and tweaks, which I will now do (well tomorrow, rather than now!). Mikenorton (talk) 23:03, 30 July 2024 (UTC)

Many thanks once again. Much appreciated. Ben MacDui 09:05, 31 July 2024 (UTC)

Obsidian composition

Thanks for restoring the text that I added earlier today in the Obsidian article about its chemical composition. Thanks also for adding a supporting source reference citation. I had been trying to add that specific source while my original edit was being reverted after only 3 minutes with accompanying unfounded accusation of my text being original research. (When I raised an objection to the reversion/OR accusation at the overzealous reverting editor's talk page, it too was reverted). Takes all sorts I suppose. GeoWriter (talk) 18:30, 17 August 2024 (UTC)

You're welcome. The OR accusation was laughable, it was hardly controversial and just a cn tag would have sufficed or they could have waited to see if a citation turned up over the next day or two. Too many people in a hurry. Mikenorton (talk) 19:43, 17 August 2024 (UTC)

Isle of the Sea

Hi Mike - you will have noticed the little flurry of publicity about the geology of those lonely isles, the Garvellachs. This article and those for the individual isles were mostly tiny stubs and I am spending a bit of time adding to them in case of further such excitements. A kind editor added something about the geology and, if you haven't done so already, I'd be grateful if you would take a quick peek in case I am missing something important about global Sturtian glaciation or the islands' role in the matter. Cheers, Ben MacDui 10:21, 23 August 2024 (UTC)

Hi MacDui, I will take a look. I can't help wondering if the results are a little "oversold", fascinating though they are. The use of Youngest Single Grains produces results consistent with the Sturtian but don't actually prove it, but that's just my take. Mikenorton (talk) 22:40, 3 September 2024 (UTC)

Thanks once again. I fear you are right - but then what is journalism without a little hyperbole? Ben MacDui 08:59, 7 September 2024 (UTC)

Not a problem MacDui, I removed some of the hyperbole, but kept the one bit that seemed fair enough. I did remove the bits about the university - if anyone's interested in the "who", they can check out the journal paper or the BBC article. After going into the paper in more detail, I'm actually more convinced than I was. I'm a little unsure about the link to the Laurentian Mountains, as I suspect that the authors actually mean the Laurentian Shield, although that should really be the Canadian Shield according to our article. I'll take another look to see if it's clearer about exactly what they're referring to. Mikenorton (talk) 11:02, 7 September 2024 (UTC)

Now linked to Laurentia after a re-read. Mikenorton (talk) 12:24, 7 September 2024 (UTC)

I think that we need an article on the Port Askaig Tillite Formation. I'll work on that while I'm waiting for my latest "procedure" as they call operations these days. It will also give me something to concentrate on during my post-op recovery. Mikenorton (talk) 12:44, 7 September 2024 (UTC)

Good luck with both! Ben MacDui 12:55, 7 September 2024 (UTC)

Thanks!! Mikenorton (talk) 12:58, 7 September 2024 (UTC)

Procedure successfully completed and new article available. Mikenorton (talk) 13:12, 10 September 2024 (UTC)

Great stuff. It's on my watchlist and I shall be looking out for the Garbh Eileach Formation. Ben MacDui 14:05, 10 September 2024 (UTC)

That may take a while - there's only a single source, the Rugen et al. (2024) paper, which defines it as separate to the Lossit Limestone. Mikenorton (talk) 14:28, 10 September 2024 (UTC)

The Lossit Limestone Formation, however ....... maybe a short paragraph or two in that article would cover it. Mikenorton (talk) 14:47, 10 September 2024 (UTC)

1908 Messina earthquake

Hello. I just wanted to contribute some confusion. While the death toll of the 1908 Messina earthquake is listed on the list of deadliest natural disasters and in it's own article as 75 to 82k, for some reason on the list of deadliest earthquakes and tsunami the death toll is listed as 123k. Should we fix this error? Nagito Komaeda the Second (talk) 16:43, 9 October 2024 (UTC)

@Nagito Komaeda the Second: - Hi, I've just spent a lot of time trying to find out where that 123,000 figure came from, but have so far drawn a blank. It gets quite a few mentions, but not in sources that I would regard as particularly reliable for earthquake death tolls. Certainly the source used in the list of natural disasters by death toll#Tsunamis is probably not one that we should be using, if other better sources exist - it does list some sources, but I still can't work out where the 123,000 came from. I've changed the number and citation on the other page and used the CFTI5 Italian catalogue to support ~80,000. I'll need to change the citation in the list of tsunamis as well. Thanks for pointing out the discrepancy. Mikenorton (talk) 12:48, 12 October 2024 (UTC)

Thank you. Now we just need to fix the death toll for the list of tsunamis and everything should be fine. Nagito Komaeda the Second (talk) 12:58, 12 October 2024 (UTC)

Hutton's Unconformity: is it "great"?

Skiing a little off-piste from our current chat on Talk:Great Unconformity...

...and now considering the description "great" possibly (or not) attaching to Hutton's Siccar Point unconformity...

I see that the article Hutton's Unconformity doesn't currently even mention any claim to being a "Great Unconformity". A short visit to Google also has difficulty providing WP:RS-quality links that associate the "great u." claim with it.

My u/grad geology was decades ago, and is now long rusted, so I'm way out of touch. Yours seems much more lively and current.

How extensive (or non-existent) is the literature that attaches the "great" label to Siccar Point? Can we (for the moment, at least) simply forget about any "great u." reference to Siccar Point?

Feline Hymnic (talk) 12:47, 23 November 2024 (UTC)

@Feline Hymnic: - It's rarely used for the Siccar Point outcrop, Archer et al. (2018) is one of the few. Mostly when it is used, it is generally as "the great unconformity at Siccar Point" rather than it being known as the "Great Unconformity". I don't think that it worth a mention in the "Hutton's Unconformity" article. Given that, I think that we can just remove it from the Great Unconformity article and keep that as the title. Maybe just put Hutton's Unconformity in the "See also" section. Mikenorton (talk) 19:43, 23 November 2024 (UTC)
