Earthquake Insurance in Tennessee: Do You Actually Need It? (New Madrid, the Real Math)
Updated 2026-07-04 · by a licensed Lumenbo agent
Ask most Tennessee homeowners if their insurance covers an earthquake and they'll assume it does. It doesn't. Earthquakes are excluded from standard homeowners policies — and almost no one in the state buys the coverage that fills the gap. Here's the honest math on whether you should.
Yes, Tennessee has earthquake risk
Tennessee sits on two seismic zones: the New Madrid fault in West Tennessee — one of the most significant seismic areas in the central U.S. — and the East Tennessee Seismic Zone. Scientists estimate roughly a 25–40% chance of a magnitude 6.0 or greater earthquake in the central U.S. within a 50-year window.
In any given year that's a low probability. But a major New Madrid event would cause catastrophic, widespread damage — the kind that rebuilds a house from the foundation up.
Your homeowners policy won't cover it
Standard homeowners policies exclude earth movement, which lumps earthquakes together with sinkholes and landslides. So an earthquake that cracks your foundation or collapses a wall is on you — unless you've specifically added earthquake coverage by endorsement or bought a standalone policy.
This is the same "earth movement" exclusion that leaves sinkholes uncovered by default in Tennessee (a separate coverage carriers are required to offer) — which is why so many homeowners are surprised twice.
The real math: cheap premium, big deductible
Here's the honest picture:
- Premium: because Tennessee is comparatively low-risk, coverage is often inexpensive — sometimes around $200 a year.
- Deductible: earthquake deductibles are percentage-based and high — commonly 10% to 25% of your coverage. On a $300,000 dwelling limit, a 10% deductible is $30,000.
That combination tells you what earthquake insurance is for: it's catastrophe protection. It won't pay for a hairline crack, but if a major quake makes your home a total loss, a modest annual premium stands between you and a six-figure rebuild you'd otherwise pay entirely out of pocket.
So is it worth it?
For many Tennessee homeowners, the low premium makes it a reasonable endorsement to carry — especially in West Tennessee, closer to New Madrid, and for anyone whose home is their largest asset and who couldn't self-fund a total rebuild. It's a personal call about risk tolerance, but it's one most homeowners have never actually been offered the chance to make.
If your carrier doesn't offer earthquake coverage, that's not the end of the conversation — some carriers add it by endorsement, and there are standalone options when they don't.

Frequently asked
Does my homeowners insurance cover earthquakes?
No. Standard homeowners policies exclude earth movement — which includes earthquakes, along with sinkholes and landslides. Earthquake coverage has to be added by endorsement or bought as a separate policy. Many Tennessee homeowners assume they're covered and aren't.
Is Tennessee really at risk for earthquakes?
Yes. Tennessee sits on two seismic zones: the New Madrid fault in West Tennessee and the East Tennessee Seismic Zone. Estimates put the chance of a magnitude 6.0 or greater quake in the central U.S. at roughly 25–40% within a 50-year window. It's low-probability in any given year, but the potential damage is catastrophic.
How much does earthquake insurance cost in Tennessee?
Because Tennessee is comparatively low-risk, premiums are often modest — sometimes around $200 a year, depending on the home, location, and construction. That's part of what makes it worth at least considering.
What's the catch with the deductible?
Earthquake deductibles are percentage-based and high — commonly 10% to 25% of your coverage amount. On a $300,000 dwelling limit, a 10% deductible is $30,000. So earthquake coverage is really catastrophe protection: it's there for the big, home-destroying event, not minor cracks.
Can I get earthquake coverage even if my carrier doesn't offer it?
Usually yes. Some carriers add it by endorsement; when they don't, there are standalone options. If your current company doesn't offer it, that doesn't mean you can't get it — it means you need an agent who can source it.
