Earthquake Insurance: What It Covers and Who Needs It

An earthquake policy is unusual because the question is rarely whether the potential loss could be large. A severe quake can damage the foundation, frame, walls, utilities and contents of a home at the same time.

The harder question is whether the probability and financial exposure justify paying a separate premium for a policy that can carry a five-figure deductible. That decision requires looking at the earthquake risk, the structure and your finances together.

Does Homeowners Insurance Cover Earthquakes?

Standard homeowners insurance generally excludes direct earthquake and earth-movement damage.

NAIC states that catastrophic earthquake damage is not covered by a standard homeowners policy. Coverage is typically available through a separate earthquake policy or an endorsement to another property policy.

That means an HO-3 or HO-5 policy can be broad in many other ways and still leave earthquake shaking outside the contract. “Open peril” does not mean every cause of loss is insured; exclusions still apply.

Our guide to homeowners insurance exclusions explains why flood, earthquake, wear and other gaps remain even under broad policy forms.

There is an important distinction between the earthquake itself and another covered peril that follows it.

Do not assume every chain of events will be divided the same way. The cause of damage and wording in both policies determine which insurer responds.

What Does Earthquake Insurance Cover?

Earthquake insurance is designed primarily for direct physical damage caused by earthquake shaking.

NAIC describes earthquake coverage as insurance for the home and other covered property damaged by an earthquake. Specific policies differ, but the main coverage categories commonly include:

Do not assume the earthquake policy simply duplicates homeowners Coverages A–F. Earthquake products can use different limits, deductibles and restrictions.

Dwelling Coverage

The dwelling section is the most important part for a homeowner because it provides funds to repair or rebuild covered earthquake damage to the house.

Check whether the dwelling limit tracks the reconstruction amount on your homeowners policy and whether extensions, foundations or other structural components receive the protection you expect.

Some earthquake policies place special limits or exclusions on items such as masonry veneer, chimneys, swimming pools, landscaping, retaining walls or other property. Those restrictions vary, so read the policy rather than relying on a generic coverage list.

Personal Property

Personal-property coverage can protect furniture, clothing, electronics and other covered belongings damaged by earthquake shaking.

Look at the actual limit rather than assuming it equals the contents limit on your homeowners policy. Valuable or fragile property can have special limits or exclusions.

Loss of Use

If covered earthquake damage makes the home uninhabitable, loss-of-use coverage can help with qualifying additional living expenses such as temporary housing.

This protection can be especially valuable after a severe quake because structural inspections, infrastructure disruptions and contractor shortages can extend the period before a home is safe to occupy.

However, loss-of-use limits and deductibles vary by policy.

What Earthquake Insurance May Not Cover

Earthquake insurance should not be treated as an all-disaster policy.

NAIC says it typically focuses on direct damage from earthquake shaking and generally does not replace coverage already provided by homeowners insurance.

Depending on the policy, exclusions or restrictions can apply to:

• Fire following an earthquake when the homeowners policy covers the fire
• Flooding or tsunami-related water damage
• Sewer or drain backup
• Vehicles
• Land, landscaping, trees and plants
• Swimming pools and spas
• Fences and certain detached structures
• Exterior masonry or veneer
• Some fragile or high-value personal property
• Pre-existing damage
• Wear and tear, deterioration or neglect

The distinction between earthquake and flood is particularly important.

If an earthquake contributes to a tsunami, lake overflow or another qualifying external flood, the earthquake policy generally does not become flood insurance. Separate flood coverage may be needed for the water damage.

Earthquake Deductibles Can Be Much Larger Than Home Deductibles

The deductible is one of the most important reasons an earthquake policy can look stronger on paper than it feels after a moderate claim.

Earthquake deductibles are commonly expressed as a percentage of the insured value rather than as a simple dollar amount.

NAIC’s current earthquake topic page says earthquake deductibles generally range from about 2% to 20% of total insured property value, although individual markets and policies can differ.

A 15% deductible does not mean you pay 15% of the repair bill. If the policy bases the deductible on a $500,000 dwelling limit, the deductible is $75,000 under that simplified example.

Policies can also handle dwelling, contents and other coverages differently. NAIC warns that separate deductibles may apply depending on the contract.

This makes earthquake coverage fundamentally different from choosing between a $1,000 and $2,500 ordinary homeowners deductible.

California CEA Deductibles: A Current Example

California Earthquake Authority provides a useful example of how much earthquake products can vary.

CEA’s current homeowners options offer dwelling deductibles of 5%, 10%, 15%, 20% or 25%, although some lower-deductible choices are unavailable for certain high-value or older unretrofitted homes. CEA also offers different structures under its Standard Homeowners and Homeowners Choice products.

CEA’s loss-of-use coverage is not subject to a deductible under its current homeowners policies.

These are California-specific CEA terms, not nationwide defaults.

Who Should Consider Earthquake Insurance?

There is no nationwide rule that everyone above a particular seismic-hazard score should buy earthquake insurance.

A more useful decision combines four questions.

1. How Much Earthquake Hazard Exists Where You Live?

The West Coast receives much of the attention, but earthquake hazard is not limited to California.

The latest USGS National Seismic Hazard Model found that nearly 75% of the United States could experience potentially damaging earthquake shaking. Thirty-seven states have experienced an earthquake above magnitude 5 during the last 200 years.

USGS updated its consumer guidance in July 2026 and recommends using its state-by-state earthquake information and national hazard maps rather than simply measuring distance from the nearest fault. Ground shaking can depend on faults, soil, geology and other regional factors.

Areas with significant hazard include parts of:

• California
• Alaska
• Washington and Oregon
• Nevada and Utah
• Hawaii
• The New Madrid region in the central U.S.
• Parts of the central and eastern United States with known seismic zones

The list is not a ranking and does not replace the USGS hazard information for a specific location.

2. How Vulnerable Is the House?

Two neighboring homes can experience the same shaking and suffer very different damage.

Construction characteristics can materially affect vulnerability. Factors worth investigating include:

• Age of the home
• Whether the house is adequately anchored to its foundation
• Raised or cripple-wall foundations
• Unreinforced masonry
• Living space above a garage or other soft-story configuration
• Hillside construction
• Heavy chimneys or masonry features
• Previous seismic retrofit work

A qualified structural professional can evaluate vulnerabilities that an insurance quote cannot.

3. Could You Absorb the Loss Yourself?

Earthquake insurance becomes more valuable when a severe uninsured loss would threaten the household’s finances.

Consider:

• How much it would cost to repair or rebuild the home
• How much home equity is at risk
• How much cash and liquid savings you could use after a disaster
• Whether you could carry both housing costs and major repair debt
• How much personal property you could afford to replace
• Whether temporary housing would strain the budget

A homeowner with substantial liquid assets may decide to self-insure more earthquake risk. A homeowner with limited savings and significant equity can reach the opposite conclusion even if the premium feels expensive.

4. Could You Afford the Deductible?

Buying earthquake insurance does not eliminate the need for earthquake savings.

If a $500,000 home has a $75,000 earthquake deductible, the household still needs a plan for that retained loss.

Compare the deductible with:

• Emergency savings
• Available credit
• Expected repair needs after a moderate quake
• The amount of damage required before the policy begins producing meaningful value

A policy with a deductible you could never fund may still protect against a catastrophic total loss, but it will behave very differently from ordinary first-dollar coverage.

Do Not Rely on Federal Disaster Aid Instead

Federal disaster assistance can help after a presidentially declared disaster, but it is not a replacement for property insurance.

FEMA states that its Individuals and Households Program provides help for eligible uninsured or underinsured necessary expenses and serious needs, and that the assistance cannot compensate for all disaster losses.

Homeowners may also be eligible for SBA disaster loans after qualifying declared disasters. As of 2026, SBA says eligible homeowners may apply for up to $500,000 to repair or replace a primary residence and renters or homeowners may be eligible for up to $100,000 for personal property.

A loan is debt, not an insurance settlement.

Government assistance also depends on the disaster declaration, eligibility and program rules. It should not be treated as a guaranteed source of full rebuilding funds when deciding whether to insure a six-figure earthquake exposure.

How to Compare Earthquake Insurance Policies

Earthquake quotes can be difficult to compare because the premium is only one moving part.

Line up the following before choosing a policy:

1. Dwelling limit: Does it reflect a credible rebuilding amount?
2. Dwelling deductible: Convert the percentage into dollars.
3. Personal-property limit: Is it enough for the belongings you want insured?
4. Personal-property deductible: Is it separate from the dwelling deductible?
5. Loss-of-use limit: How much temporary housing protection is available?
6. Other structures: Are detached garages, sheds or other structures covered?
7. Building-code coverage: How are required upgrades treated?
8. Masonry and fragile property: Look for exclusions or special limits.
9. Emergency repairs: Check whether immediate protective work receives coverage.
10. Seismic-event definition: Determine how the policy treats aftershocks and multiple earthquakes.

Then compare price. Our separate guide to earthquake insurance costs covers premiums, current California market data, rating factors and deductible economics in more detail.

Do not compare a 5% deductible quote with a 20% deductible quote as though the cheaper premium is the only difference.

Retrofitting Can Reduce the Risk Even if You Buy Insurance

Insurance transfers financial risk. A seismic retrofit tries to reduce the physical damage in the first place.

USGS and earthquake-resilience programs recommend measures based on the building’s vulnerabilities. Depending on the home, work can involve foundation anchoring, bracing cripple walls, strengthening soft-story configurations or securing components that can fail during shaking.

California Earthquake Authority currently offers qualifying older wood-frame homeowners premium discounts of up to 25% when eligible seismic retrofit requirements are met.

CEA’s eligibility rules are specific to California and particular construction types, but the broader lesson applies nationally: ask whether your insurer recognizes verified mitigation and whether a structural professional recommends retrofitting the house.

Insurance and mitigation are complements, not substitutes. A stronger house can reduce the size of a loss; insurance can protect the household when the remaining loss is still too large to absorb.
