Earthquake Insurance — Is It Worth It?

If you live in a seismic risk zone and are weighing earthquake insurance, the honest answer is: standard homeowners policies exclude earthquake damage entirely. Earthquake coverage costs $800-$3,500 per year with 10-25% deductibles — meaning on a $500K rebuild, you'd owe $50K-$125K before insurance pays anything. Worth it in California, Pacific Northwest, and the New Madrid Seismic Zone; typically overkill elsewhere.

Okoniq Property Hub stores insurance policies + rebuild cost estimates so seismic coverage decisions are data-driven.

Why is it separate?

Standard homeowners insurance excludes earthquake damage because:

• Catastrophic and concentrated (many claims at once)
• Difficult to price accurately
• Small pool of buyers
• Historical carrier losses in past quakes

Separate earthquake policy or rider required.

Where is earthquake risk high?

Per USGS Seismic Hazard Maps:

Very High Risk:

• California — most of state
• Alaska — south and southeast
• Pacific Northwest (Cascadia subduction zone) — Oregon and Washington coast

High Risk:

• Pacific Northwest inland (Portland, Seattle)
• Utah (Wasatch Front)
• Nevada (western)
• New Madrid Seismic Zone (Missouri, Arkansas, Tennessee, Kentucky, Illinois)
• Puerto Rico and US Virgin Islands
• Hawaii

Moderate Risk:

• South Carolina (Charleston area)
• Northeast (Boston, NYC)
• Yellowstone region

Low Risk:

• Most of central, southern, and eastern US

Check your specific location with USGS.

Cost

Wildly variable by location, home age, and construction:

• California high-risk: $1,500-$3,500/year for $200K coverage
• California moderate: $800-$1,500/year
• Pacific Northwest: $500-$1,500/year
• Utah/Nevada: $400-$1,000/year
• Moderate-risk East Coast: $200-$600/year
• Low-risk anywhere: $100-$300/year

The deductible problem

Earthquake policies have LARGE deductibles:

• California Earthquake Authority (CEA): 5-25% deductible
• Private carriers: 10-25% deductible

On a $500K home with a 15% deductible: you owe $75K before insurance pays anything.

For total loss scenarios, this still leaves you far better off than uninsured. For partial damage, you may pay full repair costs without insurance help.

What's covered

Typical policy covers:

• Structural damage from earthquake
• Content damage (often lower limit, $100K typical)
• Additional living expenses (temp housing)
• Emergency repairs

Not covered:

• Fire from earthquake (covered by homeowners)
• Tsunami damage (flood coverage territory)
• Landslide from earthquake (varies)
• Cracked foundation from settling (not quake-related)

When earthquake insurance makes sense

• California, Pacific Northwest — high probability of significant damage in a career-length timeframe
• New Madrid Zone — long-cycle risk but consequences catastrophic
• Older home — pre-1980 construction more vulnerable
• Un-retrofitted foundation — vulnerable regardless of location
• High-value home — larger loss to protect

When it's probably not

• Low-risk zones with modern construction
• Rental property where landlord policy already excludes it
• If total earthquake premium exceeds 1% of home value per year AND risk is moderate

The California Earthquake Authority

CEA is a public entity providing earthquake insurance in California:

• Standardized policies
• ~1M policies in force
• 60%+ of CA earthquake insurance market
• Retrofitting can qualify for premium discounts

Non-CA states have private carriers and state-specific programs.

Frequently asked questions

Can I get earthquake insurance if my house is on a hill?

Depends on carrier. Some exclude hillside properties; others charge premium. Landslide risk overlaps.

What about renter's earthquake insurance?

CEA and private carriers offer renter-specific earthquake coverage — protects contents, not the building.

Does retrofitting reduce premiums?

Yes — bolt-and-brace foundation retrofits qualify for premium discounts, often 20%+. CEA maintains list of approved retrofits.

Not insurance advice. Earthquake coverage depends on location and property specifics — consult a licensed insurance agent. Okoniq Property Hub keeps policies organized. Get started free.
