GEOLOGY

Detailed explanation-1: -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-2: -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-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. There are two ways by which we can measure the strength of an earthquake: magnitude and intensity.

Detailed explanation-4: -The focus of an earthquake is the point underground where rocks first begin to move. Seismic waves travel outward from the earthquake’s focus. The epicenter is the point on Earth’s surface directly above the focus.

Detailed explanation-5: -The place where a fault ruptures is called the focus or origin, and the point directly above on the earth’s surface is called the epicentre. The pulse of energy released by a fault movement radiates outwards as seismic waves, or shock waves.
