GEOLOGY

Detailed explanation-1: -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: -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-3: -Therefore, the focus of an earthquake is the epicenter.

Detailed explanation-4: -The point where the earthquake originates is called the seismic focus. The point on the Earth’s surface vertically above the focus is called its epicentre.

Detailed explanation-5: -The point at which the Earthquake happens below the Earth’s Surface is the Focus of the Earthquake. At the focus the waves generated and that waves moved in a large area to spread the damage of Earthquake.
