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.
Example from peninsular plateau: We present observations of active faulting within peninsular India, far from the surrounding plate boundaries.
