Earthquake Insurance: Do You Need It Outside California?

When you hear "earthquake insurance," you probably think of California. And it's true—California experiences the most frequent and damaging earthquakes in the U.S. But earthquakes don't respect state lines. If you live in a seismically active area outside California, you could still face significant risk—and potentially devastating financial loss. This article will help you understand earthquake risk nationwide and decide if earthquake insurance is worth considering.

Where Do Earthquakes Occur in the United States?

According to the U.S. Geological Survey (USGS), damaging earthquakes can happen in nearly every state. While the West Coast is most active, other regions have moderate to high seismic risk:

• Alaska experiences the most earthquakes of any state. The 1964 Good Friday earthquake (magnitude 9.2) remains the largest recorded in North America.
• Oregon and Washington are part of the Cascadia subduction zone, capable of producing magnitude 9.0 earthquakes and tsunamis.
• Nevada, Utah, Idaho, Montana, and Wyoming have active fault zones, such as the Wasatch Fault in Utah.
• Central U.S. (New Madrid Seismic Zone)—including parts of Missouri, Arkansas, Tennessee, Kentucky, and Illinois—experienced massive quakes in 1811–1812. Scientists estimate a 7–10% chance of a magnitude 7.5+ earthquake in this zone in the next 50 years (USGS, New Madrid Seismic Zone).
• South Carolina (Charleston) and the East Coast have moderate risk. The 1886 Charleston earthquake (magnitude 7.0) caused widespread damage.
• Hawaii experiences frequent volcanic and tectonic earthquakes.
• Oklahoma and parts of the Midwest have seen increased seismicity from induced earthquakes (wastewater injection), though many are small (USGS).

How Earthquake Insurance Works (and Why It's Different)

Standard homeowners insurance does not cover earthquake damage. You must purchase a separate earthquake policy or an endorsement. These policies are available through private insurers or, in California, through the California Earthquake Authority (CEA). In other states, coverage is offered by private companies.

Earthquake insurance typically covers:

• Structural damage to your home (dwelling coverage)
• Personal property
• Additional living expenses if your home is uninhabitable

But it often comes with high deductibles—typically 10% to 20% of the dwelling coverage amount. For a $300,000 home, that means a deductible of $30,000–$60,000. This is much higher than standard homeowners deductible ($500–$2,000).

FEMA’s Earthquake Program emphasizes that earthquake insurance is designed to help you recover from a catastrophic event, not minor damage. It's not for covering cosmetic cracks but for major structural repairs.

Should You Buy Earthquake Insurance Outside California?

The decision depends on your specific risk, financial situation, and tolerance for uncertainty. Consider these factors:

1. Your Home's Seismic Risk Zone

Check the USGS Seismic Hazard Maps. If you're in a high-risk area (like the Wasatch Front in Utah, the New Madrid zone, or coastal Oregon/Washington), the probability of a damaging quake within your mortgage period may be significant.

2. Your House's Construction Type

Homes built before modern seismic codes (typically pre-1980) are more vulnerable. Unreinforced masonry, brick, or homes without proper foundation bolting are at higher risk. If your house is newer and built to code, it may withstand shaking better.

3. Your Financial Ability to Self-Insure

If you have substantial savings and could pay for major repairs out of pocket (say, $50,000+), you might choose to self-insure. However, after a large earthquake, federal disaster assistance is often limited to low-interest loans (from the Small Business Administration) and not grants for homeowners. FEMA's Individuals and Households Program can provide temporary housing and limited repair funds, but not enough to rebuild a home.

4. The Cost of Insurance vs. Potential Loss

Earthquake insurance premiums vary widely. In high-risk areas outside California, annual premiums might range from $500 to $3,000+ for a single-family home. Deductibles are high, so the insurance essentially covers catastrophic losses above that threshold. Compare the premium cost to your home's replacement cost and your deductible.

Real-World Scenarios: When Insurance Makes Sense

• Homeowner in Seattle, WA: Living in the Cascadia subduction zone, your home could face a magnitude 9.0 earthquake. The cost of rebuilding could be $300,000+. Insurance may be pricey but could save you from financial ruin.
• Homeowner in Memphis, TN: In the New Madrid Seismic Zone, the risk of a major quake is moderate but real. If you have an older brick home, insurance could be wise.
• Homeowner in Salt Lake City, UT: The Wasatch Fault is active. The estimated return period for a major quake is about 1,300 years, but the potential damage is severe—especially for unreinforced masonry homes.

Steps to Make an Informed Decision

1. Visit USGS Earthquake Hazards to see the risk map for your area.
2. Get quotes from a few licensed insurance agents who offer earthquake coverage in your state. Ask about deductibles and limits.
3. Assess your home's vulnerability—consider a seismic retrofit if you have an older home. Retrofitting can reduce damage and may lower your insurance premium.
4. Review your emergency savings and other resources. Could you afford a $40,000 deductible after losing your home?
5. Consider the Ready.gov Earthquake Safety guidance for preparedness steps to take regardless of insurance.

Conclusion

Earthquake insurance is not just a California concern. If you live in a moderate- to high-risk zone outside California, it's worth serious consideration. The decision boils down to your risk tolerance and financial ability to recover. While premiums and deductibles can be high, a major earthquake can leave you with a destroyed home and limited federal aid. Weigh the costs carefully, but don't dismiss coverage just because you don't live on the San Andreas Fault.
