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. 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 or emergency repairs needed immediately after a quake.
Personal Property Coverage
This covers your household belongings — furniture, electronics, clothing, and appliances — that are damaged in a quake event. Personal property coverage is often set as a percentage of your dwelling limit (typically 50–75%), though high-value or fragile items like artwork, ceramics, or dishes may need additional riders. 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 anywhere from $1,500 to over $100,000 and typically last for a reasonable repair period. For policies similar to flood insurance, which also requires separate coverage, this kind of protection can make 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%–20% being the most common. 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 & Regions
The USGS estimates that roughly 75% of the U.S. faces the potential for damaging earthquake shaking over a 100-year period. However, risk is far from evenly distributed:
| State/Region | Hazard Level | Key Risk Factor |
|---|---|---|
| California | 🔴 Very High | San Andreas Fault; 300+ faults capable of M6+ |
| Alaska | 🔴 Very High | Alaskan-Aleutian Megathrust; most frequent quakes nationwide |
| Hawaii | 🔴 High | Volcanic activity and frequent seismic events |
| Pacific Northwest (WA/OR) | 🟠 High | Cascadia Subduction Zone — potential M9+ megathrust |
| Nevada | 🟠 Medium-High | Proximity to California fault systems |
| New Madrid Zone (MO, AR, TN, IL) | 🟠 Medium | Major intraplate fault; long overdue for a major event |
| Charleston, SC area | 🟡 Moderate | Historical M7+ event in 1886; risk often underestimated |
| East Coast (general) | 🟢 Low | Rare events; lower premiums reflect lower risk |
If you live near a known fault line, the Pacific coast, or in 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?
Annual premiums vary widely based on your state, proximity to fault lines, home age, construction type, and the deductible you choose. Here's a general breakdown:
| State/Region | Risk Level | Avg. Annual Premium |
|---|---|---|
| California (high-risk zones, e.g., Los Angeles) | Very High | $800 – $1,300+ |
| Alaska | Very High | $700 – $1,500+ |
| Pacific Northwest (WA/OR) | High | $300 – $800 |
| Nevada | Medium-High | $400 – $900 |
| Missouri / New Madrid Zone | Medium | $200 – $600 |
| Texas | Moderate | $500 – $800 |
| East Coast | Low | Under $300 |
As a general rule of thumb, earthquake insurance runs approximately $0.50 to $15 per $1,000 of dwelling coverage, with the rate driven heavily by your risk zone. For a $300,000 home, that translates to anywhere from $150 to $4,500 per year.
The California Earthquake Authority (CEA): How It Works
The California Earthquake Authority is a publicly managed, state-created entity that sells residential earthquake insurance to Californians through participating private insurance agents. It's the largest provider of residential earthquake insurance in the United States, backing approximately 1.5 million policies.
Here's how the CEA functions:
- You purchase through your insurance agent, not directly from the CEA
- Premiums are set actuarially and adjusted annually based on current seismic science
- Claims are paid from reserves built from premiums, reinsurance, and state-backed bonds if reserves are depleted after a major event
- Dwelling coverage is available up to $3 million
- In 2025, the CEA implemented a 6.8% rate increase across all policies to maintain financial solvency
CEA vs. Private Earthquake Insurance
For California homeowners, the CEA is often the primary option — and sometimes the only practical one — due to the reluctance of private insurers to take on significant seismic risk in high-hazard zones. Outside of California, private earthquake insurance policies (often added as an endorsement to a standard home policy) are the norm.

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 national map. 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 & 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.
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.

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 package, earthquake-caused damage to your dwelling, personal property, and additional living expenses requires a separate earthquake insurance policy or a 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. This is why earthquake insurance is best thought of as protection against catastrophic loss rather than minor damage.
How does the California Earthquake Authority (CEA) work? The CEA is a state-managed nonprofit entity that sells earthquake insurance to California homeowners through private insurance agents. It sets rates based on seismic science, backs claims through premium reserves, reinsurance, and state bonds if necessary, and covers up to $3 million in dwelling damage. In 2025, the CEA raised rates by 6.8% to maintain long-term solvency.
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 in the Midwest, premiums have been rising sharply — from roughly $57/year in 2000 to over $569/year by 2023 — reflecting growing awareness of seismic risk in non-coastal states.
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. Renters don't need dwelling coverage (that's the landlord's responsibility), so earthquake coverage for renters is typically much less expensive than for homeowners — making it an easy add-on worth considering in high-risk areas.
