Ground Shaking
Main hazard created by earthquakes. Severity at any one point depends on range of factors: strength of earthquake, distance from epicenter, distance from epicenter, local geological conditions. Longer the shaking, more damage will be caused.
1 of 6
Landslides, rock and snow avalanches
Occur in mountainous areas when slopes are weakened by strong shaking and eventually give way (crack open).
2 of 6
Tsunamis
Seismic waves that result when earthquakes occur beneath the sea. Can travel with enormous speed and cause devastation along the coast.
3 of 6
Liquefaction
The shock waves cause ground water to rise to the surface, turning soft ground to mud. Any buildings built on clay, for example, sink into the mud and collapse.
4 of 6
Fault
A fracture in the Earth's crust that shows signs of movement.
5 of 6
Richter Scale
Measures earthquakes (goes up to 9.9).
