GEOLOGY

Detailed explanation-1: -An earthquake’s point of initial rupture is called its hypocenter or focus. The epicenter is the point at ground level directly above the hypocenter.

Detailed explanation-2: -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-3: -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-4: -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-5: -This shaking and trembling causes the movement of a series of shock waves on the earth’s surface. Earthquakes are caused by the sudden breaking and movement of the tectonic plates of the earth’s rocky outermost crust. Earthquakes typically occur on plate boundaries. Every earthquake has a focus and an epicentre.
