fault In geology, a fracture in the Earth's crust along which movement occurs. The result of plate tectonics, faults are classified according to the type of movement. Vertical movements in the crust cause normal and reverse faults, while horizontal movements result in tear faults. Faults can occur in groups creating horsts, block mountains, grabens, or rift valleys.
