What is an earthquake insurance?

Is a form of property insurance that pays the policyholder in the event of an earthquake that causes damage to the property. Most ordinary homeowners insurance policies do not cover earthquake damage. Most earthquake insurance policies feature a high deductible, which makes this type of insurance useful if the entire home is destroyed,

but not useful if the home is merely damaged. Rates depend on location and the probability of an earthquake. Rates may be cheaper for homes made of wood, which withstand earthquakes better than homes made of brick.

As with flood insurance or insurance on damage from a hurricane or other large-scale disaster, insurance companies must be careful when assigning this type of insurance, because an earthquake strong enough to destroy one home will probably destroy dozens of homes in the same area. If one company has written insurance policies on a large number of homes in a particular city, then a devastating earthquake will quickly drain all the company's resources. Insurance companies devote much study and effort toward risk management to avoid such cases.

Should you buy earthquake insurance?
To consider our own circumstances and needs when deciding if earthquake insurance is a good buy. There isn't one answer for everyone, but for most people their home is their major asset. Protecting it just makes good sense.

An earthquake endorsement generally excludes damages or losses from floods and tidal waves – even when caused or compounded by an earthquake. However, loss caused by landslide, settlement, mudflow and the rising, sinking and contracting of earth may be covered if the damage resulted from an earthquake.

Earthquake insurance in California
Earthquake insurance has become a political issue in California, whose residents purchase more earthquake insurance than residents of any other state in the U.S. After the 1994 Northridge earthquake, nearly all insurance companies completely stopped writing homeowners' insurance policies altogether in the state, because under California law (The "mandatory offer law"), companies offering homeowners' insurance must also offer earthquake insurance. Eventually the legislature created a "mini policy" that could be sold by any insurer to comply with the mandatory offer law: only structural damage need be covered, with a 15% deductible. Claims on personal property looses and "loss of  use" are limited. The legislature also created a quasi-public (privately funded, public managed) agency called CEA California Earthquake Authority. Membership in the CEA by insurers is voluntary and member companies satisfy the mandatory offer law by selling the CEA mini policy. Premiums are paid to the insurer, and then pooled in the CEA to cover claims from homeowners with a CEA policy from member insurers. The state of California specifically states that it does not back up CEA earthquake insurance, in the event that claims from a major earthquake were to drain all CEA funds, nor will it cover claims from non-CEA insurers if they were to become insolvent due to earthquake losses.
