Fault
Faults are fractures or fracture zones in the Earth's crust along
which one side moves with respect to the other. A fault scarp
is a cliff or steep slope that sometimes forms along the fault at
the surface. There are many types of faults (for example, strike-slip,
normal, reverse, and thrust faults) ranging in size from a few
tens of meters to hundreds of kilometers in dimension.

fault system, south flank of Kilauea Volcano, Hawai`i.
In Hawai`i, these tall cliffs are called "pali's".
