What Does Earthquake Insurance Cover?
Earthquake insurance fills a major gap that your standard homeowners policy leaves wide open. Most homeowners don't realize that earthquakes are explicitly excluded from standard home insurance until it's too late. To understand the full list of what your basic policy ignores, see our guide on common home insurance exclusions. A separate earthquake policy, or an endorsement added to your existing policy, typically covers three core areas:
Dwelling Coverage
This is the backbone of any earthquake policy. It pays to repair or rebuild the physical structure of your home after damage from ground shaking, surface ruptures, soil liquefaction, landslides, or slope failure. This includes your foundation, walls, roof, built-in appliances, attached garages, and decks. Coverage limits should reflect your home's replacement cost, not its market value (those two numbers can be very different). Some policies also include optional riders for building code upgrades (now up to $30,000 under the CEA) or emergency repairs needed immediately after a quake. Earthquake-related foundation damage is one of the most expensive losses a homeowner can face, often exceeding $25,000 even without total collapse.
Personal Property Coverage
This covers your household belongings (furniture, electronics, clothing, and appliances) that are damaged in a quake event. Under a CEA homeowners policy, personal property coverage starts at $5,000 and can be increased up to $25,000. High-value or fragile items like artwork, ceramics, or dishes may need additional riders, and separate deductibles frequently apply to this portion of your policy.
Additional Living Expenses (ALE)
Also called "loss of use" coverage, ALE pays for the increased costs of daily living while your home is being repaired or is uninhabitable. This can include hotel stays, meals, laundry, storage, furniture rental, and temporary housing. Depending on the insurer, ALE benefits can range from $1,500 to over $100,000 (CEA's standard ALE limit is now $200,000 on its Homeowners Choice policy). For policies similar to flood insurance, which also requires separate coverage, this kind of protection can mean the difference between financial survival and disaster.

Understanding Earthquake Insurance Deductibles
This is where most homeowners get a serious surprise. Earthquake insurance deductibles are almost always percentage-based, not a flat dollar amount like the $1,000 or $2,000 deductible you may have on your homeowners policy.
Typical earthquake deductibles range from 5% to 25% of your dwelling's insured value, with 10% to 20% being most common. The California Earthquake Authority offers deductibles of 5%, 10%, 15%, 20%, and 25% (in 5% increments). What does that actually look like?
| Home Insured Value | 5% Deductible | 10% Deductible | 15% Deductible | 20% Deductible |
|---|---|---|---|---|
| $200,000 | $10,000 | $20,000 | $30,000 | $40,000 |
| $400,000 | $20,000 | $40,000 | $60,000 | $80,000 |
| $600,000 | $30,000 | $60,000 | $90,000 | $120,000 |
| $800,000 | $40,000 | $80,000 | $120,000 | $160,000 |
This means earthquake insurance is designed primarily to protect you from catastrophic losses, not minor cracks or cosmetic damage. If your $500,000 home suffers $35,000 in quake damage and your deductible is 10% ($50,000), you receive nothing from your insurer.
Lower deductibles (like 5%) come with higher annual premiums but significantly reduce your out-of-pocket exposure after a major event. Higher deductibles reduce your premiums but shift enormous financial risk back to you.

Who Needs Earthquake Insurance? Risk Zones Explained
Standard homeowners policies from any insurer exclude earthquake damage. So the question isn't really "should I add earthquake insurance?" but rather "how high is my risk, and can I afford not to have it?"
Highest-Risk States and Regions
The USGS 2023 National Seismic Hazard Model estimates that roughly 75% of the U.S. faces the potential for damaging earthquake shaking over the next 100 years. However, risk is far from evenly distributed:
| State/Region | Hazard Level | Key Risk Factor |
|---|---|---|
| California | 🔴 Very High | San Andreas, Hayward, San Jacinto faults; >99% chance of M6.7+ in 30 yrs |
| Alaska | 🔴 Very High | Alaskan-Aleutian Megathrust; ~12,000 M3+ quakes yearly |
| Hawaii | 🔴 High | Volcanic activity and frequent seismic events |
| Pacific Northwest (WA/OR) | 🟠 High | Cascadia Subduction Zone, potential M9+ megathrust |
| Nevada | 🟠 Medium-High | Active Basin and Range faulting |
| New Madrid Zone (MO, AR, TN, IL) | 🟠 Medium | Memphis area is among USGS's highest-risk inland populations |
| Charleston, SC area | 🟡 Moderate | Historical M7+ event in 1886; risk often underestimated |
| Oklahoma/Texas | 🟡 Moderate | Induced seismicity from wastewater injection |
| East Coast (general) | 🟢 Low | Rare events; lower premiums reflect lower risk |
If you live in Washington state, Oregon, California, or the New Madrid Seismic Zone, earthquake insurance deserves serious consideration. Even in "moderate" zones, a single major event can cause total losses that no emergency fund can cover alone.
How Much Does Earthquake Insurance Cost in 2026?
Annual premiums vary widely based on your state, proximity to fault lines, home age, construction type, and the deductible you choose. Here's a 2026 breakdown based on current market data:
| State/Region | Risk Level | Avg. Annual Premium (2026) |
|---|---|---|
| California (Bay Area, high-risk zones) | Very High | $2,500 – $5,000+ |
| California (statewide average) | Very High | $1,300 – $2,750 |
| Alaska | Very High | $700 – $1,500+ |
| Pacific Northwest (WA/OR) | High | $300 – $800 |
| Nevada | Medium-High | $400 – $900 |
| Missouri / New Madrid Zone | Medium | $300 – $600 |
| Texas | Moderate | $500 – $800 |
| East Coast | Low | Under $300 |
In California, recent data shows earthquake insurance averages roughly $3.54 per $1,000 of coverage, translating to about $2,478 per year for a $700,000 home. Premiums can climb dramatically in high-risk Bay Area ZIP codes, where coastal areas like Alameda average closer to $6.50 per $1,000 of coverage (about $4,550/year on a $700,000 home). On the East Coast, the same coverage often costs less than $0.50 per $1,000.
The California Earthquake Authority (CEA): How It Works
The California Earthquake Authority is a publicly managed, privately funded nonprofit that sells residential earthquake insurance to Californians through participating private insurance agents. It is the largest provider of residential earthquake insurance in the United States, providing roughly two-thirds of all residential earthquake policies in California. Only about 13% of California homeowners currently carry earthquake coverage, leaving the vast majority financially exposed.
Here's how the CEA functions in 2026:
- You purchase through your insurance agent, not directly from the CEA
- Premiums are set actuarially and adjusted annually based on updated seismic models and reinsurance costs
- Claims are paid from reserves built from premiums, reinsurance, and state-backed bonds if reserves are depleted
- Dwelling coverage equals your underlying homeowners Coverage A limit
- Personal property limits start at $5,000 and go up to $25,000
- Loss of Use (ALE) covers up to $200,000 with no deductible
- Building code upgrade coverage is available up to $30,000
CEA vs. Private Earthquake Insurance
For California homeowners, the CEA is often the primary (and sometimes only) practical option in high-hazard zones, since many private insurers won't take on significant seismic risk. Outside California, private earthquake insurance policies (often added as an endorsement) are the norm. If you rent rather than own, you can still protect your belongings through a renters insurance policy with an earthquake endorsement.
Is Earthquake Insurance Worth It?
There's no universal answer, but here's a clear framework for making the decision based on your personal situation:
Use This 3-Factor Test to Decide
1. Location Risk Look up your home's seismic hazard rating on the USGS 2023 National Seismic Hazard Model. If you're near an active fault or in a known seismic zone (California, Pacific Northwest, New Madrid), earthquake insurance is a strong candidate. If you're in a low-hazard zone with little seismic history, the math may not favor it.
2. Home Value and Replacement Cost The higher your home's replacement cost, the higher your premium and your deductible exposure. For a $600,000 home with a 10% deductible, you'd need $60,000 on hand before insurance kicks in. If you couldn't cover that from savings, insurance becomes more essential, not less. This is especially important for homes with complex structural damage exposure where rebuild costs can climb fast.
3. Your Financial Situation Ask yourself: "If an earthquake destroyed 60% of my home, could I rebuild without insurance?" For most homeowners, the answer is no. Earthquake insurance is most valuable when the cost of a policy is modest relative to the financial devastation it prevents. If you're also a landlord, consider how earthquake damage could impact rental income, something landlord insurance also addresses. As of 2025, the EBB program also expanded to include rental and non-owner-occupied properties.
Frequently Asked Questions
Does homeowners insurance cover earthquakes? No. Standard homeowners insurance policies explicitly exclude earthquake damage. Whether you have a basic HO-3 policy or a premium comprehensive HO-5 policy, earthquake-caused damage to your dwelling, personal property, and additional living expenses requires a separate earthquake insurance policy or specific endorsement. However, if an earthquake causes a fire, your standard homeowners policy typically does cover the fire damage.
What is a typical earthquake insurance deductible? Earthquake deductibles are almost always percentage-based, typically ranging from 5% to 25% of your home's insured dwelling value. A 10% deductible on a $400,000 home means you pay the first $40,000 out of pocket before your insurer pays anything. In California, the CEA offers deductibles in 5% increments, though homes valued over $1 million or older raised-foundation homes without verified retrofits are limited to a 15% minimum.
How does the California Earthquake Authority (CEA) work? The CEA is a state-created nonprofit, privately funded entity that sells earthquake insurance to California homeowners through participating insurance agents. It writes about two-thirds of California's residential earthquake policies and covers dwelling limits equal to your underlying homeowners Coverage A, up to $25,000 in personal property, and up to $200,000 in loss-of-use coverage. Retrofitted homes can qualify for premium discounts of up to 25%.
Is earthquake insurance worth buying in a low-risk state? In most low-risk states, earthquake insurance is inexpensive (often under $300/year) and the likelihood of a major quake is slim. Whether it's worth it depends on your risk tolerance and financial situation. Even in moderate-risk zones like the New Madrid Seismic Zone, premiums have been rising as seismic risk awareness grows, but coverage often remains affordable enough to be worth considering.
Can renters get earthquake insurance? Yes. Renters can purchase earthquake insurance to protect their personal belongings and cover additional living expenses if their rental unit becomes uninhabitable after a quake. Since renters don't need dwelling coverage (that's the landlord's responsibility), earthquake coverage for renters is typically much less expensive than for homeowners, making it an easy add-on worth considering in high-risk areas.
