GEOLOGY

Detailed explanation-1: -The point within the earth along the rupturing geological fault where an earthquake originates is called the focus, or hypocenter. The point on the earth’s surface directly above the focus is called the epicenter.

Detailed explanation-2: -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. Sometimes an earthquake has foreshocks.

Detailed explanation-3: -The focus is point inside the earth where the earthquake started, sometimes called the hypocenter, and the point on the surface of the earth directly above the focus is called the epicenter.

Detailed explanation-4: -The spot underground where the rock first breaks is called the focus, or hypocenter of the earthquake. The place right above the focus (at the ground surface) is called the epicenter of the earthquake. Cutaway view of the reverse fault. The earthquake starts at the focus, with slip continuing along the fault.

Detailed explanation-5: -The place where a fault ruptures is called the focus or origin, and the point directly above on the earth’s surface is called the epicentre. The pulse of energy released by a fault movement radiates outwards as seismic waves, or shock waves.
