Earthquake Coverage Sits Outside The Homeowners Policy

Standard American homeowners policies exclude earth movement. Earthquake protection is bought separately, and the separate product is priced on a logic that makes it look strange next to ordinary home insurance.

Correlated risk breaks ordinary pooling

Home insurance works because house fires happen to one household at a time while everyone's premium sits in the pool.

An earthquake damages thousands of buildings in one moment. The losses are correlated, so the pool that funds them must be enormous relative to the number of policies.

That correlation drives high deductibles, reinsurance dependence and, in some states, dedicated public or quasi-public entities created to make the coverage available at all.

Deductibles are percentages and often apply separately

Earthquake deductibles are typically stated as a percentage of coverage and set well above what homeowners policies use for other perils.

Some policies apply separate deductibles to the dwelling, to contents and to loss of use, so one event can involve more than one deductible.

The design means the coverage is aimed at structural catastrophe rather than at cracked plaster, which surprises policyholders who expect a homeowners-style response.

The excluded cause matters more than the visible damage

The exclusion covers earth movement broadly, which can include landslide, mudflow, sinking and settling depending on the wording.

Policies commonly restore coverage for fire following an earthquake, treating the resulting fire as a separate covered peril.

Because several perils can operate in sequence, causation questions in these claims are genuinely complex and are resolved on facts and state law rather than intuition.

Retrofitting changes the risk and sometimes the price

Bolting a house to its foundation, bracing a cripple wall and securing water heaters reduce the damage a given shake produces.

Some programs offer premium credits or grants for documented retrofits, and availability varies by state and by year.

Mitigation reduces the physical exposure regardless of whether coverage is purchased, which is its own argument.

Availability is a state question

Earthquake coverage is sold by private insurers in some states, through state-created entities in others, and is priced very differently across seismic zones.

Nothing here indicates whether a particular loss would be covered, which turns on the policy wording, the cause and the state.

A licensed agent, the state insurance department or a structural engineer for the mitigation questions are the right next steps, and the terms available change over time.
