Seismology, the study of seismic waves, is the most reliable source of information regarding the Earth’s interior. As P and S waves travel through the Earth, they change speed and direction (refract) when they encounter different densities and states of ...
The Earthquake focus, also known as the hypocenter, is the exact point within the Earth’s crust where the initial rupture of rocks occurs. This is the origin point from which energy is released in the form of seismic waves. Its ...
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 ...
