Q:

What is the Focus of an Earthquake?

Answer

A Focus of an earthquake is the location where the earthquake begins. The ground ruptures at this spot, then seismic waves radiate outward in all directions.

At this focus point, the release of energy due to faulting actually occurs during an earthquake. The point directly above the focus on the surface is called Epicenter.


The focus is also called as Hypocenter as it is the synonym of the focus.
