All Natural Hazard Risks
The bar chart below shows the degree of exposure to
natural hazards and the percentage of area affected.
Tsunamis and storm surges are a threat to coastal
regions, particularly gulfs, bays, and estuaries. Flood
hazard results from river floods and torrential rain.
Drought is caused by major deviations from the normal
amounts of precipitation. Frost hazard depends on
elevation and latitude.

Earthquake intensity zones indicate where there is a 20% probability that degrees of
intensity shown on the map will be exceeded in 50 years.
Tropical storm intensity zones indicate where there is a 10% probability of a storm of this
intensity striking in the next 10 years.
