The document provides information about earthquakes, including:
1) It describes the elastic rebound theory which explains how energy is stored in rocks until a fault causes an earthquake, releasing the energy in seismic waves.
2) It defines the focus as the point where faulting begins underground, and the epicenter as the point directly above on the surface.
3) It identifies the four types of seismic waves - P and S waves which travel through solids, and Rayleigh and Love waves which travel along the surface.
