1. Summarize earthquake hazards and the damage they can cause.
2. Explain how safe building practices and earthquake prediction can prevent earthquake damage.

For people living in earthquake hazard zones, earthquakes can be both frightening and potentially life threatening. Although in the United States we have made tremendous strides in the fields of earthquake preparedness and building safety, the potential for damage and loss of life still exists. Earthquake risk maps are used by geologist and building planners to better design communities while reducing the risk to its members.
During the ground shaking some of the dirt takes on the properties of a liquid.
Large underwater or costal earth quakes can create immense tidal surges (tidal waves). The resulting wave travels very quickly across the ocean.
Damage to structures and individuals have been greatly reduced by the adoption and implementation of building codes designed to relieve the stress of buildings and foundations following an earthquake.
The prediction of earthquakes relies on three factors.
Assumptions used in the prediction of earthquakes.
