GEOLOGY

Detailed explanation-1: -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.

Detailed explanation-2: -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-3: -The epicenter, epicentre or epicentrum is the point on the Earth’s surface that is directly above the hypocenter or focus, the point where an earthquake or underground explosion originates.

Detailed explanation-4: -The epicentre is the worst affected area on the Earth’s surface when the earthquake occurs. The point inside the earth right under the epicentre is called the focus.

Detailed explanation-5: -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.
