What Is Earthquake Insurance?

Updated July 9, 2026 6 min read

Cracked foundations and shifted framing rarely show up on the list of things a standard homeowners policy pays for, even though a home is more likely to sit in earthquake territory than most people assume.

The short answer

Earthquake insurance is a separate policy, or sometimes an add-on to an existing policy, that covers damage caused by seismic activity, which is typically excluded from standard homeowners and renters insurance. It generally covers structural damage to the home and, depending on the policy, personal belongings damaged in the event. Because it’s usually sold apart from a standard policy, coverage doesn’t exist automatically just because someone has homeowners insurance in general.

Why it’s excluded from standard policies

Like flooding, earthquakes can cause widespread, simultaneous damage across a large area, which makes them a different kind of risk than an isolated house fire or a single burst pipe. That regional concentration of risk is a major reason insurers generally carve earthquake coverage out of standard homeowners policies and price it separately, similar to how flood damage is also typically excluded and sold on its own. Pricing it separately allows insurers to account for a region’s specific seismic risk rather than spreading that cost evenly across all policyholders everywhere.

What it typically covers

Earthquake policies commonly address the structure of the home, other structures on the property, and personal belongings, though coverage details and limits vary by insurer and policy. Many earthquake policies come with a notably higher deductible than a standard homeowners policy, sometimes calculated as a percentage of the home’s insured value rather than a flat dollar figure. Understanding how deductibles generally work is useful background here, since an earthquake policy’s deductible structure can look quite different from what a policyholder is used to on other coverages.

Who tends to need it

Earthquake risk isn’t limited to one part of the country, though it’s more concentrated in certain regions with known fault activity. Homeowners in areas with elevated seismic risk are the most obvious candidates for this coverage, but risk assessments and building codes vary widely by location, so it’s worth evaluating the actual risk for a specific property rather than assuming coverage is or isn’t necessary based on general geography alone. Renters can generally purchase a version of this coverage too, focused on personal belongings rather than the structure, since the building itself is typically the landlord’s responsibility to insure.

What it costs

Premiums for earthquake coverage depend heavily on location, the age and construction type of the home, and the deductible chosen. Older homes or those built before modern seismic building codes were adopted may cost more to insure, since they’re generally considered more vulnerable to damage. A home that’s been retrofitted with seismic reinforcements may qualify for a lower premium, since the underlying structural risk is reduced. As with any optional coverage, weighing the premium against the potential cost of rebuilding or repairing a home after significant seismic damage is part of the underlying decision.

A practical habit

Earthquake insurance is worth a second look any time a homeowner reviews their broader coverage, not just once at move-in. Revisiting it periodically, alongside a broader look at what a homeowners policy does and doesn’t include, helps make sure a gap this significant isn’t left unexamined simply because it wasn’t top of mind when the original policy was purchased. A move to a new home, a renovation, or simply a new insurance renewal cycle are all reasonable prompts to ask the question again rather than assuming last year’s decision still fits.
