Standard Tennessee home insurance does not cover earthquake damage. A homeowners, renters, or condo policy excludes it, so a cracked foundation or collapsed wall from a quake is paid only if you carry separate earthquake coverage. That gap matters most in West Tennessee and the Memphis metro, which sit inside the New Madrid Seismic Zone, the most active seismic zone in the country east of the Rocky Mountains, according to the U.S. Geological Survey (USGS). To cover earthquake shaking, a home needs either a stand-alone earthquake policy or an earthquake endorsement added to an existing policy.
Does home insurance cover earthquakes in Tennessee?
No. Earthquake is a named exclusion on standard property policies. A peril is simply a cause of loss, such as fire, wind, or theft. Standard homeowners insurance covers many perils, but earthquake and earth movement are carved out of the base policy.
The same exclusion runs through the other standard forms. Renters insurance does not cover quake damage to your belongings, and condo insurance does not cover quake damage to the parts of the unit you own.
Picture a Memphis homeowner whose house shifts during a New Madrid quake. The foundation cracks and a chimney topples. Under a standard policy, the claim for that shaking is denied, because earthquake was never part of the base coverage. The homeowner pays for repairs out of pocket unless a separate earthquake policy or endorsement was in place before the quake.
This is different from flood, which is also excluded from standard home policies and needs its own flood insurance. Earthquake and flood are separate gaps, each closed by its own coverage.
Where is Tennessee's earthquake risk, and why Memphis?
Tennessee's earthquake risk is concentrated in the west of the state. It comes from the New Madrid Seismic Zone (NMSZ), a system of faults that the USGS identifies as the most active seismic zone in the United States east of the Rocky Mountains. A seismic zone is an area where earthquakes are more likely because of stress along underground faults.
The NMSZ runs through West Tennessee and includes the Memphis metropolitan area. Cities and counties across that corner of the state sit closest to the faults, which is why earthquake insurance shows up as a real consumer topic there rather than a distant possibility.
The state treats it that way too. The Tennessee Department of Commerce and Insurance (TDCI), the agency that regulates insurance in Tennessee, publishes a Consumer Guide for Earthquake Insurance. A state insurance regulator producing a guide on the topic signals that earthquake coverage is a genuine Tennessee question, not a niche add-on.
What are the odds of a New Madrid earthquake?
The USGS estimates a 25 to 40 percent chance of a magnitude 6 or larger earthquake in the New Madrid Seismic Zone within the next 50 years. A magnitude 6 quake is strong enough to damage buildings that were not built or retrofitted to handle shaking.
Put that range next to a mortgage. A 30-year loan on a Memphis-area home falls well inside that 50-year window, so a buyer today is financing a house through part of the period the USGS is describing. The risk is not a certainty, and it is not remote either.
Numbers like these come from the USGS hazard models, not from any single carrier or from Olive Cover. The figure is what a homeowner can point to when deciding whether the earthquake gap in a standard policy is one they want to leave open.
Why does Memphis shaking travel farther than a western quake?
The ground under the central United States carries seismic energy differently than the ground out west. Geologists call this attenuation. In plain terms, attenuation is how quickly shaking fades as it moves away from the quake. Where attenuation is low, the shaking fades slowly and reaches farther.
The New Madrid region has low attenuation, according to the USGS. So a given earthquake damages a wider area than a quake of the same size would in California, where the shaking dies out faster over distance.
For a homeowner, that changes the map of who feels a quake. A single New Madrid event can rattle homes across a broad stretch of West Tennessee, not only the blocks nearest the fault. A house that sits some distance from the epicenter can still take structural damage, because the energy did not weaken as much on the way there.
How does earthquake coverage work in Tennessee?
Earthquake coverage is bought either as a stand-alone earthquake policy, a separate contract that covers quake damage, or as an earthquake endorsement, an add-on attached to an existing home policy. An endorsement is a written change that adds or adjusts coverage on a policy you already hold.
Both routes exist because earthquake was removed from the base policy in the first place. Adding it back takes a deliberate step, whether that step is a new policy or a rider on the current one.
The coverage generally follows the structure of the home policy it sits beside. It can respond to damage to the dwelling, which is the structure of the house itself, and often to personal belongings and additional living costs if the home is unlivable after a quake. What the coverage will and will not pay is spelled out in the policy language, which is why reading the specific contract matters more than any general summary.
What is the earthquake deductible, and why is it higher?
Earthquake coverage usually carries a percentage deductible. A deductible is the amount you pay before coverage starts. Most home policies use a flat dollar deductible, such as $1,000. Earthquake coverage instead sets the deductible as a percentage of the dwelling limit, and that percentage is typically higher than a standard all-perils deductible.
The median owner-occupied home in Tennessee is valued at $286,700, according to U.S. Census Bureau QuickFacts (ACS 2020-2024). On a home insured near that value, a 10 percent earthquake deductible works out to about $28,670. The homeowner would absorb roughly that amount of quake damage before the earthquake coverage paid a dollar.
The size of that deductible is the reason earthquake coverage is usually built for large, structural losses rather than small cracks. A minor repair can fall entirely under the deductible. A partial collapse is where the coverage does its work. The exact percentage and dollar figure vary by policy, so the number on any given contract is the one that counts.
What does earthquake insurance cover, and what does it exclude?
Earthquake coverage responds to loss caused by earthquake shaking, subject to the percentage deductible and the policy limits. It commonly extends to the dwelling, to personal property, and to added living expenses when a quake makes the home uninhabitable.
Some losses that follow a quake fall to other policies. Fire that starts after an earthquake is often handled by the standard home policy, because fire is a covered peril on the base form. A quake that leads to flooding involves separate flood insurance, since flood is its own exclusion. The lines between these coverages live in the policy documents, so the wording is where the answers are.
The table below lays out the split between a standard home policy and earthquake coverage after a quake.
Standard home policy vs earthquake coverage: what each pays after a quake
| Loss after a New Madrid quake | Standard home policy | Earthquake policy or endorsement |
|---|---|---|
| Cracked foundation or shifted structure from shaking | Not covered (excluded) | Covered, after the percentage deductible |
| Belongings broken by the shaking | Not covered | Often covered, after the deductible |
| Extra living costs if the home is unlivable | Not covered for quake cause | Often covered |
| Fire that ignites after the quake | Often covered (fire is a base peril) | Not the primary payer |
| Flooding that follows the quake | Not covered (needs flood insurance) | Not covered (needs flood insurance) |
| Deductible structure | Flat dollar amount | Percentage of the dwelling limit |
Every cell above describes how these coverages generally work. The controlling detail is always the specific policy, and a licensed advisor can walk through whether earthquake coverage fits your situation.
What should you verify before a quake?
A homeowner looking at the earthquake gap can check a short list of facts against the actual policy. Confirm whether any earthquake endorsement is already attached, since most standard policies have none by default. Read the deductible as a percentage and translate it into a dollar figure on your own home value, the way the $28,670 example did above.
Check what the coverage includes beyond the structure, such as belongings and living expenses, and note the exclusions that send certain losses to other policies. If the home carries a mortgage, the loan runs for years, which is the same window the USGS uses when it describes New Madrid odds.
When a claim does happen, the process runs through the carrier that wrote the coverage. General information on how home claims proceed lives on the claims resource, and the carriers page explains how an independent agency works with different insurers. These decisions are personal, and a licensed advisor can walk through whether earthquake coverage fits a specific home and budget.
