Standard homeowners and renters insurance generally do not cover losses caused directly by earthquakes, which is why earthquake coverage is typically purchased separately or added through a separate endorsement where available.
The direct answer: earthquake is usually excluded
The U.S. Geological Survey states that homeowners and renters insurance policies generally do not cover losses related to earthquakes.
Separate earthquake insurance may be available through private insurers, state-related programs, or endorsements depending on the market.
This makes earthquake similar to flood in one important way: the physical hazard can exist even though standard homeowners coverage generally excludes the cause of loss.
It differs from flood in policy structure, market availability, deductibles, and the science used to describe the hazard.
Hazard Clarity does not recommend whether anyone should purchase earthquake insurance. It explains public seismic hazard data for the address.
Earthquake risk is not just a California issue
California has frequent and highly visible earthquake risk, but the United States has many seismic regions.
The USGS 2023 National Seismic Hazard Model covers all 50 states. When releasing the updated map in 2024, USGS said nearly 75 percent of the United States could experience damaging earthquake shaking over a 100-year period.
That statement does not mean 75 percent of U.S. homes are likely to be damaged or that all those locations have equal hazard.
The hazard varies enormously.
The New Madrid seismic zone in the central United States, the Pacific Northwest Cascadia subduction zone, Alaska, Hawaii, Utah, Nevada, and other regions all have meaningful seismic considerations.
A buyer should therefore check the address rather than relying on a state stereotype.
What does a seismic hazard map actually show?
USGS seismic hazard maps estimate the likelihood and intensity of earthquake ground shaking over specified time periods.
They are used in building codes, engineering, public policy, risk assessment, and insurance-related modeling.
The map does not predict the date of the next earthquake.
It also does not tell you whether a specific house will survive an event. Building age, foundation type, construction, retrofit history, soil conditions, and the characteristics of the earthquake all affect potential damage.
A seismic result describes ground-shaking hazard; it does not inspect the building.
Why earthquake damage can be expensive even when the house remains standing
Earthquake losses are not limited to total structural collapse.
Ground shaking can damage foundations, masonry, chimneys, walls, utility connections, contents, and building systems. Fire following an earthquake can create a separate cause-of-loss question under some policies.
The exact treatment of fire following earthquake depends on policy and state law.
This is a good example of why homeowners should not assume that every loss occurring during an earthquake is treated identically.
If you are reviewing an actual policy, ask how earthquake, earth movement, fire following earthquake, and additional living expenses are handled.
Earthquake insurance often uses percentage deductibles
Separate earthquake insurance frequently uses percentage-based deductibles rather than a standard flat-dollar homeowners deductible.
The percentage may apply to the dwelling limit or another specified amount depending on the policy.
A homeowner can therefore have a relatively small standard homeowners deductible and a much larger earthquake deductible.
Do not assume that one deductible applies to both policies.
Actual deductible options vary by state, insurer, and program.
What does earthquake insurance generally cover?
Coverage structures vary.
A separate earthquake policy may include dwelling damage, personal property, and additional living expense subject to separate limits and deductibles. Some policies can have exclusions or sublimits for specific property.
This article cannot describe one standard earthquake contract because the products are not uniform nationally.
If you are considering coverage, review the actual policy form and ask a licensed professional about limits, deductibles, exclusions, and available endorsements.
Hazard Clarity does not compare earthquake policies.
Does homeowners insurance cover a tsunami?
Tsunami damage creates another cause-of-loss distinction.
A tsunami is a series of ocean waves, often triggered by an undersea earthquake, that can inundate coastal land. The resulting inundation is a flood-type hazard rather than ordinary earthquake shaking damage.
Standard homeowners insurance generally excludes flood.
A single earthquake can therefore trigger separate seismic, fire, and flood-related insurance questions.
This is why hazard categories should remain separate even when the events are connected physically.
Does homeowners insurance cover landslides after an earthquake?
Earth movement exclusions can be broad.
Landslide, mudflow, subsidence, and other earth movement can be treated differently depending on policy language and cause.
Do not assume that buying earthquake insurance automatically covers every form of earth movement.
If slope failure or landslide is a concern for a property, that topic requires a separate policy and geologic review beyond a general earthquake article.
The earthquake screen does not assess landslide risk.
What if the home was built to modern seismic codes?
Modern building codes can improve seismic performance, but code compliance is not a guarantee against damage.
Building codes are minimum standards designed around life safety and performance objectives, and requirements vary by location and construction era.
An older home may have been retrofitted. A newer home may still contain nonstructural vulnerabilities.
For buyers in meaningful seismic zones, consider having qualified professionals evaluate foundation anchoring, cripple walls, masonry chimneys, soft-story conditions, and other locally relevant issues.
That is building advice, not insurance advice.
Earthquake hazard can affect insurance pricing and availability
USGS notes that national seismic hazard maps are used in insurance rate-setting and other risk decisions.
Insurers may combine seismic hazard with construction, soil, building value, concentration of insured properties, and private catastrophe models.
A public USGS map therefore has relevance to insurance without being an insurance quote.
The public seismic result does not reproduce an insurer’s model.
A high seismic-hazard result does not tell you what earthquake insurance will cost. A low result does not prove coverage is unnecessary.
Buyers should check earthquake exposure before closing
If you are moving to a new region, review seismic hazard at the address before relying on assumptions.
Then ask whether standard homeowners insurance excludes earthquake, what separate earthquake options exist, how the deductible is structured, and whether the property has known seismic retrofits.
Mortgage lenders generally require homeowners insurance, but they do not universally require earthquake insurance. Loan-program and property requirements can differ.
Whether to purchase separate earthquake coverage is an individual decision for the buyer and licensed insurance professional.
How Hazard Clarity uses USGS data
Hazard Clarity turns public USGS information into plain-language property context.
Use the seismic indicator and its source explanation to understand ground-shaking context for the address, including places outside the best-known earthquake regions.
The report does not calculate structural damage, predict the next earthquake, prescribe retrofits, or recommend insurance coverage.
Those limitations make the report more credible.
