How do earthquakes start?
Earthquakes are usually caused when underground rock suddenly breaks and there is rapid motion along a fault. This sudden release of energy causes the seismic waves that make the ground shake.
Where do earthquakes start?
hypocenter
The spot underground where the rock first breaks is called the focus, or hypocenter of the earthquake. The place right above the focus (at the ground surface) is called the epicenter of the earthquake. Cutaway view of the reverse fault. The earthquake starts at the focus, with slip continuing along the fault.
