Fault (geology)
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 movements. Large faults within Earth's crust) result from the action of plate tectonic forces, with the largest forming the boundaries between the plates, such as the megathrust faults of subduction zones or transform faults. Energy release associated with rapid movement on active faults is the cause of most earthquakes. Faults may also displace slowly, by aseismic creep.
Fault (geology)
A fault plane is the plane) that represents the fracture surface of a fault. A fault trace or fault line is a place where the fault can be seen or mapped on the surface. A fault trace is also the line commonly plotted on geological maps to represent a fault.
