A mudflow or mud flow is a form of mass wasting involving "very rapid to extremely rapid surging flow" of debris that has become partially or fully liquified by the addition of significant amounts of water to the source material.
Mudflows contain a significant proportion of clay, which makes them more fluid than debris flows; thus, they are able to travel farther and across lower slope angles. Both types are generally mixtures of various kinds of materials of different sizes, which are typically sorted by size upon deposition.
Mudflows are often called mudslides, a term applied indiscriminately by the mass media to a variety of mass wasting events. Mudflows often start as slides, becoming flows as water is entrained along the flow path; such events are often called flow slides.
Other types of mudflows include lahars (involving fine-grained pyroclastic deposits on the flanks of stratovolcanoes) and jökulhlaups (outbursts from under glaciers or icecaps).
A statutory definition of "flood-related mudslide" appears in the National Flood Insurance Act of 1968, as amended, codified at 42 USC Sections 4001 and following. The NAS [National Academy of Sciences] has reported several studies of 'mudslides'.
Mudslide is a colloquial term for mudflow, the most rapid and fluid type of earth movement.

Mudslide is an EP by English rock band The Bluetones, released in 2000. "Mudslide" was also included on the band's 2006 compilation A Rough Outline: The Singles & B-Sides 95–03.
Jonathan Gooch (born 22 August 1984 in Hertfordshire, England), more commonly known by his stage names Feed Me and Spor, is a drum and bass, dubstep and electro house producer and DJ. He is currently managed by Three Six Zero Group.
Jon Gooch obtained the name Spor after an authentication of particular IP identities. After a successful partnership with Renegade Hardware and Barcode Recordings, and releases with Teebee's Subtitles Recordings, in 2006, Spor and long-term friend Chris Renegade launched Lifted Music and signed music from producers such as Apex, Evol Intent, Ewun and Phace.
On 24 February 2010, Spor released his second double EP, Conquerors and Commoners, on the Lifted Music label. In an interview with K Magazine, he said the title was inspired by a quote by Harlan Ellison. The album was well received by drum and bass fans, with two of the tracks from the album ("Halogen" and "Kingdom") being played on Andy C's Nightlife 5 mix CD. Spor has since then been playing his music at clubs across the world under the Lifted Music guise. Gooch was also involved in a second side project called "Seventh Stitch", which produced alternative IDM. Under this alias, he worked with another artist named Andrew Aker on a track entitled "Oceans".
