The Insurance Information Institute reports that updated maps from the U.S. Geological Survey show that 42 states are at risk for earthquakes, with 16 states at high risk, however a recent study by the I.I.I. reveals that only 7 percent of homeowners nationwide report having earthquake coverage, down from 10 percent last year.
Earthquake insurance provides protection from the shaking and cracking that can destroy buildings and personal possessions and is available from private insurance companies. In California, coverage also is available from the California Earthquake Authority (CEA). The cost of earthquake coverage varies, depending on the location of the property, how it was built and the terms of the insurance policy. The CEA website offers a premium calculator to help California residents estimate the cost of a policy for particular home.
