Frequently Asked Questions"

How much earthquake insurance should I buy?

Earthquake insurance costs are based on the value of your home. You should insure your home based on its replacement cost, which should be listed on your homeowners insurance policy.

What is the deductible on an earthquake insurance policy?

The deductible on an earthquake insurance policy varies by company, but is usually between 10% and 20%.

What is the California Earthquake Authority (CEA)?

The California Earthquake Authority (CEA) is one of the largest providers of residential earthquake insurance in the world. The CEA is a publicly managed nonprofit that partners with some of California's top insurers to help residents manage their earthquake-related risks and losses.

Does car insurance cover earthquake damage?

Your auto insurance covers earthquake damage if you have comprehensive coverage, which covers damage to your car that isn't a result of a collision.

Is there earthquake insurance for renters?

There are earthquake policies available for renters. Since renters insurance does not cover earthquake damage, it's recommended that renters purchase a separate policy to protect their personal property and help reimburse costs if their home becomes uninhabitable due to earthquake damage.

Does earthquake insurance cover tsunamis?

Whether the damage from a tsunami is covered by your earthquake insurance depends on the direct cause of the damage. If the tsunami triggers mudslides that damage your home and belongings, your earthquake insurance may cover the damage. However, any damage done by flood waters would require a separate flood insurance policy.


We analyzed sample earthquake premiums submitted by insurance companies to the California Department of Insurance. The sample included 57 companies, and actual rate samples were submitted by 35 carriers. Twenty-two carriers were excluded because they did not provide actual rates and referenced the California Earthquake Authority for rates calculations, or their earthquake insurance was underwritten by another company included in our list. Rates that were substantially higher than the majority of the quotes provided were excluded.

All rates are listed per thousand dollars of coverage. To determine your rate estimate, take the amount of coverage you need, divide it by a thousand and multiply it by the estimated rate. For example, if you need $800,000 of coverage, calculate: $800,000 / $1,000 for $800, multiplied by the study average coverage rate of $3.54, for an estimated $2,832 annual premium. The actual quote and premium you'll pay may differ and depend on where your house is located and what kind of house it is.

Earthquake statistics were gathered from FEMA, the U.S. Geological Survey and the California Earthquake Authority.
