In geology, a fault is a planar fracture or discontinuity in a volume of rock throughout which there was important displacement because of rock-mass movements. Large faults inside Earth's crust outcome from the action of plate tectonic forces, with the biggest forming the boundaries between the plates, such because the megathrust faults of subduction zones or remodel faults. Energy release associated with speedy movement on active faults is the reason for most earthquakes. Faults may displace slowly, by aseismic creep. A fault airplane is the aircraft that represents the fracture surface of a fault. A fault hint or fault line is a place the place the fault will be seen or mapped on the surface. A fault trace can also be the line generally plotted on geological maps to represent a fault. A fault zone is a cluster of parallel faults. However, the term can also be used for the zone of crushed rock along a single fault.
