GEOLOGY

Detailed explanation-1: -The surface where they slip is called the fault or fault plane. The location below the earth’s surface where the earthquake starts is called the hypocenter, and the location directly above it on the surface of the earth is called the epicenter.

Detailed explanation-2: -Seismic Gap. Seismic Gap. Region along an active fault where stress is accumulating because no earthquakes have occurred there recently. Seismic gaps are often flanked by areas that have experienced earthquakes in the near past.

Detailed explanation-3: -seismic gap. an area along a fault where relatively few earthquakes have occurred. Moho. a place within the Earth where the speed of seismic waves increases sharply; marks the boundary between the Earth’s crust and mantle.

Detailed explanation-4: -A fault is a fracture or zone of fractures between two blocks of rock. Faults allow the blocks to move relative to each other. This movement may occur rapidly, in the form of an earthquake-or may occur slowly, in the form of creep. Faults may range in length from a few millimeters to thousands of kilometers.
