GEOLOGY

Detailed explanation-1: -The focus is the place inside Earth’s crust where an earthquake originates.

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.

Detailed explanation-3: -The earthquakes originate in tectonic plate boundary. 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: -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: -Keypoints: The epicenter is a map location on the surface of the earth. The hypocenter is the point deep below the surface where the earthquake began.
