Almost half of all Americans are at risk for damage from an earthquake, according to the most recent report from the United States Geological Survey. The report says about 143 million Americans live and work in areas with at least some potential for shaking that could lead to damage in structures. About 57 million people are in areas with a moderate chance of shaking and 28 million people are in areas that have a high potential of damaging shaking.

Unfortunately, damage caused by an earthquake is a common exclusion for homeowners, condo and renters insurance policies. If you want coverage for problems related to earthquakes, you can purchase an earthquake insurance policy.

But before you take out a policy, make sure you read it closely. There are typically a lot of exclusions and limits on coverage, which should give you pause.

What Is Earthquake Insurance?

Earthquake insurance offers coverage for your home and belongings if they are damaged or destroyed in an earthquake.

A standard homeowner's insurance or renters' insurance policy doesn’t cover earthquake damage, as earthquakes aren’t covered by hazard insurance. If your house gets damaged in an earthquake, you will have to pay for the repairs yourself if you don’t have earthquake insurance. One exception is if an earthquake sparks a fire that burns your house. In that case, your home insurance policy should cover the fire-related damage since the policy covers fires. That usually also includes additional living expenses coverage that will reimburse you for living elsewhere while your house is being repaired. A July 2020 Insurance Information Institute survey found that 23% of homeowners with home coverage also have earthquake insurance. That was an increase from 15% only two years earlier. Not surprisingly, homeowners in the West hold the largest percentage of earthquake policies.

What Does Earthquake Insurance Cover?

Earthquake insurance typically covers the following:

Dwelling. This includes your house and structures attached to it. This might include concrete slab floors inside the dwelling, the foundation and other structures attached to the dwelling.
Other structures. This covers structures that are not attached to the dwelling. This might include garages, carports, storage buildings, pump houses and other structures.
Personal property. This includes furniture, clothes, appliances, dishes, pots and pans, jewelry, musical instruments, rugs and other personal items. Some items have “special limits,” meaning the policy will only pay up to a specific amount. For example, we reviewed a policy that had a $500 special limit on computers and another $500 on tools.
Additional living expenses. Also known as “loss of use,” this coverage helps pay for expenses like lodging, meals and laundry if you cannot live in your house because of earthquake damage covered by the policy.

What’s Not Covered by Earthquake Insurance?

The following items are commonly excluded on earthquake insurance policies:

Water supply systems, such as wells, irrigation systems, sprinkler systems and water reclamation systems
Underground structures or equipment outside the foundation wall of the dwelling, such as underground pipes, cables, flues and drains
Bulkheads, piers, wharves and retaining walls
Exterior masonry veneer, walls and fences
Satellite dishes and antennas
Personal property located outside of the dwelling
Awnings or other patio coverings
Landscaping, trees, shrubs, lawns or plants
Data (stored electronically or on physical records, like paper or accounting books)
Trailers designed for use with a motor vehicle
Animals, birds or fish
Decorative items or works of art, such as murals, sculptures, fountains, aquariums, stained or leaded glass, mirrors, and chandeliers
Swimming pools, spas and hot tubs
Motor vehicles
Aircraft
Watercraft
Property of tenants, roomers or boarders not related to you
Any business property or property rented to others
Personal property in any other dwelling owned, rented or occupied by you

In addition, a California Earthquake Authority policy will cover structures such as bulkheads, piers, retaining walls and masonry fences. However, these types of structures are only covered when they are integral to the stability of your dwelling.

Keep in mind, you may be able to purchase a policy that covers commonly excluded items. For example, we reviewed an American Modern Home Insurance earthquake insurance policy that included awnings, plaster, masonry chimneys, exterior water supply systems and underground structures outside the dwelling foundation.

If these types of items are important to you, it’s a good idea to compare a few different policies to get the coverage you want.

Problems Not Covered by Earthquake Insurance

Some earthquake insurance policies will not cover certain types of problems that occur right before, during or after an earthquake. This might include:

Fire (however, fire damage may be covered by your homeowners insurance)
Earth movement from a non-seismic event, such as sinking, rising, expanding or contracting of earth because of the increase or decrease in the moisture content of the soil
Water damage such as flood water, tidal water or an overflow of a body of water
Water damage which backs up through sewers or drains
Water below the surface of the ground, including seepage or flows from any part of a building or other structure, sidewalk, driveway or swimming pool
Neglect (meaning you didn’t take reasonable steps to protect your property)
Nuclear action, including radiation or discharge of a nuclear weapon, even if accidental
War (declared or undeclared), civil war, insurrection, rebellion or revolution
Wear and tear
Smog, rust, corrosion, mold, wet or dry rot, settling and animals
Defect, weakness, inadequacy, fault or unsoundness, including planning, zoning, development, design, workmanship, construction, materials and maintenance
Enforcement to repair or demolish a building or structure to comply with local building codes
Intentional acts
Explosion
Discharge, release or escape of pollutants
Theft, burglary, looting, vandalism and malicious mischief
Damage caused by motorized vehicles
Falling objects

California Earthquake Insurance

If you live in California, state law requires insurance companies to offer earthquake insurance when you purchase homeowners insurance. Your insurance company must offer you earthquake insurance every other year.

The offer must be in writing and it must tell you the policy limits, deductible and premium. You have 30 days to accept the offer. You are not required to take the policy. If you do not reply, you are rejecting the offer.

The California Earthquake Authority (CEA) provides most residential earthquake insurance policies in California (about 65%). You can’t buy a policy directly from the CEA, but you can buy it from insurance companies that are members of the CEA.

You must have a residential property insurance policy in order to buy a CEA policy. Also, you must purchase your CEA policy from the same insurance company that has your home insurance policy.

Even if you don’t purchase an earthquake policy in California, homeowners and renters insurance is required by law to cover fire damage that follows an earthquake.

Here is a California Earthquake Authority insurance premium calculator.

How Much Does Earthquake Insurance Cost?

The average cost of earthquake insurance is about $850 per year, according to AAA. Insurer Lemonade estimates a slightly lower average cost at $800 per year.

Rates for earthquake insurance depend on several factors, including:

The home’s location. If your home is an earthquake-prone area, you can expect to pay more. Homeowners in a low-risk area might pay $300 per year, while those with an older home in a high-risk area may pay as much as $2,000 per year, according to the insurer Hippo.
Age of the home. Older homes can result in higher earthquake insurance costs.
Cost to rebuild the home. This includes the replacement cost to rebuild the house using materials of similar kind and quality.
Your deductible. A deductible is what you’ll pay out-of-pocket if you file a claim. Earthquake insurance deductibles can range from 10% to 25% of the dwelling policy limit. If you choose a higher deductible, you’ll pay less premium. But keep in mind, 25% of a $100,000 policy limit means you’ll be paying the first $25,000 if you file a claim.

How much is earthquake insurance in California?

The average earthquake insurance cost in California is $738 annually, according to the California Department of Insurance. The exact cost depends on the amount of coverage, deductible, home’s risk and other factors.

The California Earthquake Authority (CEA), which provides most of the earthquake policies in the Golden State, offers earthquake insurance discounts for homes retrofitted for earthquakes. The discounts range from 10% to 25% based on the age of the home and type of foundation.

A seismic retrofit is a way to strengthen your home against earthquakes even if you don’t have an earthquake insurance policy. The CEA added that retrofitting a home can take a few weeks and makes homes safer. A retrofit doesn’t guarantee your home won’t get damaged in an earthquake, but makes it more resilient, according to the CEA.

The CEA also has an earthquake insurance premium calculator that you can use to get a residential earthquake insurance estimate.

Do I Need Earthquake Insurance?

Damage caused by an earthquake isn’t covered by a standard homeowners, renters or condo insurance policy. While earthquake insurance typically isn’t required by a mortgage lender or HOA association, it’s worth considering if you live in an earthquake-prone area.

The Modified Mercalli Intensity Scale is used to determine the severity of an earthquake. These 10 states have the “strongest shaking potential,” according to the United States Geological Survey:

California
Washington
Utah
Tennessee
Oregon
South Carolina
Nevada
Arkansas
Missouri
Illinois

Even if you don’t live in one of these states, you shouldn’t write off the possibility of an earthquake. They can happen in all 50 states.

Here are some helpful tips on how to prepare for an earthquake from the California Earthquake Authority.

How Much Earthquake Insurance Do I Need?

You need enough earthquake insurance coverage to rebuild your house if it’s destroyed, similar to needing enough homeowners insurance if your home is lost in a fire or another problem.

Your earthquake insurance company will set limits on your dwelling (house) coverage, similar to what you have on a homeowners insurance policy.

The dwelling portion provides funding to repair or rebuild your house if it’s damaged or destroyed, so you want to make sure you have enough coverage. Your insurance company will help you figure out how much dwelling coverage you need.

You also want to make sure your earthquake insurance policy has enough personal property coverage and additional living expenses coverage.

Questions To Ask Before Buying Earthquake Insurance

What are the earthquake insurance policy limits?

The maximum amount of coverage you can buy will depend on your insurance company, but keep an eye on the coverage limits. For example, if you buy an earthquake policy with only $100,000 of dwelling coverage, that might not be enough to rebuild your home if it were destroyed.

How much is an earthquake insurance deductible?

Earthquake insurance policies can have high deductibles (the amount of money you’ll pay out-of-pocket toward repairs if you make a claim). The deductible could range from 10% to 25% of the dwelling’s policy limit. If you have a $100,000 dwelling policy limit, you could be responsible for paying $10,000 to $25,000 if you file a claim.

What are the “special limits” of earthquake insurance?

Earthquake insurance policies are often filled with special limits for how much the insurer will pay to replace certain items or repair structures. For example, we found a policy that only allowed for $500 to replace a computer and another policy that pays only up to $1,000 for felled tree removal (and no more than $500 to remove any one tree) regardless of how many trees fell. Some policies won’t cover damage to a swimming pool or the deck surrounding it.

What Should I Do After an Earthquake?

If there’s been an earthquake in your area, here are several steps you can take:

Get emergency instructions from a trusted source (radio, television, internet).
Expect aftershocks, which can happen in the hours, weeks, days and even months following an earthquake.
Check utility lines and appliances for damages. If you smell gas, open the windows and turn off the main gas valve. If your electric power goes on and off, turn off your home’s circuit breaker to prevent a power surge.
Check your chimney for cracks or other damage.
If your home was damaged, take steps to prevent further damage (such as boarding windows to prevent theft).
Call your insurance agent to ask about coverage and file a claim.
Find your home inventory (if you have one).
If you need to live elsewhere because of damage, keep receipts for living expenses such as lodging and restaurant meals.
Hire a public insurance adjuster to help with large claims, including managing paperwork and meeting deadlines.
