GEOLOGY

Detailed explanation-1: -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. At the epicenter, the most vigorous shaking is caused during an earthquake.

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: -epicentre, point on the surface of the Earth that is directly above the underground point (called the focus) where fault rupture commences, producing an earthquake.

Detailed explanation-4: -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-5: -The epicenter is located on the surface directly above the focus (hypocenter), which is located on the fault at depth.
