The epicenter is the location on the Earth’s surface where the tremors are felt first. Since it is the point directly above the focus, the seismic waves (specifically P-waves) have the shortest distance to travel to reach this spot. Consequently, ...
The Elastic Rebound Theory explains the mechanical origin of earthquakes. It suggests that rocks on opposite sides of a fault are subjected to force and accumulate energy by deforming elastically. When the internal strength of the rocks is exceeded, they ...
