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 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.
