Here's what most homeowners don't realize: your standard homeowners policy specifically excludes earthquake damage. If a quake cracks your foundation, collapses a wall, or makes your home uninhabitable, you're paying for everything out of pocket — unless you have a separate earthquake policy.
What Earthquake Insurance Covers
- Dwelling coverage: Repairs or rebuilds your home's structure after earthquake damage
- Personal property: Replaces belongings damaged by the earthquake
- Additional living expenses (ALE): Pays for temporary housing, meals, and other costs if your home is uninhabitable
- Other structures: Detached garages, sheds, fences (varies by policy)
What It Does NOT Cover
- Fire after an earthquake: Actually, this IS covered by your standard homeowners policy (fire is fire, regardless of cause)
- Flooding caused by an earthquake: Requires separate flood insurance (e.g., tsunami, broken water mains, dam failure)
- Vehicle damage: Covered under your auto insurance comprehensive coverage
- Land damage: Sinkholes, landslides, and ground settling are typically excluded
- Pre-existing damage: Cracks or settling that existed before the earthquake
How Earthquake Deductibles Work (Percentage-Based)
This is the biggest surprise for most people. Earthquake insurance uses percentage deductibles, not flat dollar amounts:
- Home insured for $400,000 with a 10% deductible = you pay the first $40,000
- Home insured for $400,000 with a 15% deductible = you pay the first $60,000
- Home insured for $400,000 with a 25% deductible = you pay the first $100,000
This means earthquake insurance is designed for catastrophic events — a total or near-total loss. Minor cosmetic damage and small cracks will almost always fall below the deductible. A lower percentage deductible means a higher premium, but much less out-of-pocket in a major quake.
Who Needs Earthquake Insurance?
Highest Risk (Strongly Recommended)
- California: The San Andreas Fault makes earthquake coverage nearly essential. The California Earthquake Authority (CEA) is the primary provider
- Pacific Northwest: Washington and Oregon sit on the Cascadia Subduction Zone — the "Big One" risk
- Alaska: The most seismically active state in the U.S.
Moderate Risk (Worth Considering)
- New Madrid Seismic Zone: Missouri, Arkansas, Tennessee, Kentucky, southern Illinois, Indiana, Mississippi
- Utah: Wasatch Fault runs through Salt Lake City metro area
- South Carolina: Charleston experienced a devastating earthquake in 1886
- Oklahoma: Increased seismic activity from induced seismicity (injection wells)
Lower Risk (Case-by-Case)
Even "low-risk" areas can experience earthquakes. The 2011 Virginia earthquake was felt across the entire East Coast. If your home is your primary financial asset and you can afford the premium, earthquake coverage is worth discussing with your agent.
Construction Type Matters
Your home's construction affects both your risk and your premium:
- Wood frame: Most flexible, best at absorbing seismic movement. Lower premiums
- Steel frame: Good flexibility, moderate premiums
- Masonry/brick: Rigid, prone to cracking and collapse. Higher premiums
- Unreinforced masonry: Highest risk. Many older buildings in this category
Retrofitting your home (bolting it to the foundation, bracing cripple walls, strapping the water heater) can reduce your premium by 5-25% and dramatically improve survivability.
California Earthquake Authority (CEA)
If you live in California, the CEA is the primary earthquake insurer. It's a publicly managed, privately funded organization — not a government bailout program. Key facts:
- Available through most California homeowners insurance carriers
- Three deductible options: 5%, 10%, 15%, or 25%
- Optional contents coverage and ALE
- Premiums vary by ZIP code, construction type, age of home, and soil type
- Only about 13% of California homeowners have earthquake insurance — a concerning statistic given the risk
How to Lower Earthquake Insurance Costs
- Choose a higher deductible: 20-25% deductible costs significantly less than 5-10%
- Retrofit your home: Foundation bolting and cripple wall bracing earn premium discounts
- Reduce coverage options: Skip contents coverage if your personal property value is low relative to the deductible
- Compare carriers: Not all earthquake policies are the same — an independent agent can compare multiple options
- Consider your financial situation: If you have significant savings and low mortgage balance, a high-deductible policy may be all you need
The Bottom Line
Earthquake insurance is expensive and has high deductibles — but so is rebuilding a destroyed home with no insurance. If you live in a seismically active area, the question isn't whether an earthquake will happen, but when. Talk to an independent agent about your specific risk level and coverage options.
