Question

What is the focus of an earthquake?

Answer 1

The focus of an earthquake.

1. The focus of an earthquake is a location at some depth in the earth where seismic wave radiation begins.
2. Earthquakes are created by stress in the earth's crust, which would be caused by a variety of sources.
3. Epicenter refers to the location immediately above the focus on the surface.
4. These waves are strongest at the core and weaken as they go away.
5. The most severe earthquake damage will occur close to the epicenter. Hence, the strongest trembling occurs during an earthquake at the epicenter.

Therefore, the focus of an earthquake is the epicenter.
