Shaking causes aftershocks
What is an earthquake?
- cause great damage ... collapse of buildings and other man-made structures, broken power and gas lines (and the consequent fire), landslides, snow avalanches, tsunamis (giant sea waves) and volcanic eruptions.
Hypocenter = the location below the earth’s surface where the earthquake starts
Epicenter = the location on the surface of the earth directly above the hypocenter
