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: -The point inside the Earth where an earthquake originates is known as the focus (or hypocenter) of the earthquake. The point directly above the focus at the surface of the earth is called the epicenter of the earthquake.

Detailed explanation-4: -Epicenter is the location on the surface of the Earth directly above where the earthquake starts. Focus (aka Hypocenter) is the location in the Earth where the earthquake starts.

Detailed explanation-5: -The focus is the place inside Earth’s crust where an earthquake originates. The point on the Earth’s surface directly above the focus is the epicenter. When energy is released at the focus, seismic waves travel outward from that point in all directions.
