SOLAR SYSTEM

Detailed explanation-1: -The point where the earthquake originates is called the seismic focus. The point on the Earth’s surface vertically above the focus is called its epicentre.

Detailed explanation-2: -The point within the earth along the rupturing geological fault where an earthquake originates is called the focus, or hypocenter. The point on the earth’s surface directly above the focus is called the epicenter. Earthquake waves begin to radiate out from the focus and subsequently form along the fault rupture.
