Usually from slipping (faults and faulting) of tectonic plates or movement of fault planes, or when tectonic plates collide together. Oscillation by mechanical (man-made) means, explosions, landslides, rockfalls, and volcanic eruptions have been known to cause localized earthquakes. Underground (subsurface or near subsurface) detonations are a suspected additional cause of earthquakes.
Built up tension beneath the surface of the earth releases, like a rubber band contracting, and everything above surface is shaken.
