In geology, a fault is a planar fracture or discontinuity in a volume of rock, across which there has been significant displacement as a result of rock mass movement. Large faults within the Earth's crust result from the action of plate tectonic forces, with the largest forming the boundaries between the plates, such as subduction zones or transform faults. Energy release associated with rapid movement on active faults is the cause of most earthquakes.
A fault plane is the plane that represents the fracture surface of a fault. A fault trace or fault line is the intersection of a fault plane with the ground surface. A fault trace is also the line commonly plotted on geologic maps to represent a fault.
Since faults do not usually consist of a single, clean fracture, geologists use the term fault zone when referring to the zone of complex deformation associated with the fault plane.
The two sides of a non-vertical fault are known as the hanging wall and footwall. By definition, the hanging wall occurs above the fault plane and the footwall occurs below the fault. This terminology comes from mining: when working a tabular ore body, the miner stood with the footwall under his feet and with the hanging wall hanging above him.
Faultline is the second album of the American Avant-rock band Birdsongs of the Mesozoic, released in 1989 through Cuneiform Records.
In geology, fault line or faultline refers to the surface trace of a fault.
I kind of like this game,
'cause I've always played it safe
let a bird out of it's cage
it's gonna fly away
but the thrill of the unknown,
has lead me far away from home,
i don't think i wanna go,
back to where i used to be,
like it was before,
every time you look at me,
i want something more,
I'm starting to shake
this perfect mistake
could kill me any moment
but that's a chance i gotta take
I'm ready to fall,
break or loose it all
we're dancing on fault line,
and that's about to give away
but i think I'm gonna stay
i just wanna lie
under pretty skies
i have wished this moment
about a million times
but it's dangerous i know
why should i say no
i don't wanna have to go
back to where i used to be
and like it was before
every time you look at me
i want something more,
I'm starting to shake,
this perfect mistake,
could kill me any moment
but that's a chance i gotta take
I'm ready to fall
break or loose it all
we're dancing on fault line
and that's about to give away
but i think I'm gonna stay
and every breathe,
is just a breathe away from heartache,
and maybe i can wait
but i still wanna be you in
like a summer wind
I'm starting to shake,
this perfect mistake,
could kill me any moment
but that's a chance i gotta take
I'm ready to fall
break or loose it all
we're dancing on fault line
and that's about to give away
I'm starting to shake,
this perfect mistake,
could kill me any moment,
but that's a chance i gotta take,
I'm ready to fall
break or loose it all
we're dancing on fault line
and what's about to give away
