Home / Guides / Wildfire vs flood vs earthquake
These are the three hazards that a standard homeowners policy handles differently from everything else. Flood and earthquake are both excluded from standard coverage and need separate policies. Wildfire is a covered peril, but severe exposure can decide whether you can get or keep a policy at all. They also concentrate in different parts of the country: flood almost everywhere, wildfire across the dry West, damaging quakes along active faults. FEMA's National Risk Index rates all three for your address as expected annual loss, so you can see which one actually matters where you are.
People tend to lump "natural disaster risk" into one worry, but for a homeowner the three headline hazards behave very differently. The gap that costs the most money is insurance: two of the three are not in your policy at all, and the third can quietly become uninsurable. Here is how likelihood, coverage, and geography line up for each.
Likelihood is local, not national. Flooding is the most common and widespread natural disaster in the United States, and it is not confined to coastlines or mapped floodplains; a large share of flood claims come from properties outside high-risk flood zones. Wildfire risk clusters where dry vegetation meets development, the wildland-urban interface, and has grown across much of the West. Earthquake risk is the most geographically concentrated: it is driven by proximity to active faults, so a home can sit in a high-quake state and still be far from the hazard, or the reverse.
One caution about the National Risk Index: its rating is not a raw probability. It measures expected annual loss, which blends how often a hazard occurs with how much is exposed and how vulnerable the area is. A rural home can rate low even where a hazard is genuinely present, because there is simply less dollar value in harm's way. Read the per-hazard rating, not just the headline.
This is where the three split hardest, and it is the part worth getting right before you buy or move.
| Hazard | Standard homeowners policy | What you need separately | The catch |
|---|---|---|---|
| Wildfire | Covered. Fire is a named peril, so wildfire damage is generally included. | Usually nothing extra for the peril itself. | Availability, not coverage. In high-risk areas insurers may non-renew, decline new policies, or price premiums up sharply, pushing owners to state FAIR plans. |
| Flood | Excluded. Flood damage is not covered. | A separate flood policy, commonly through the NFIP or a private flood insurer. | Many owners assume they are covered and are not. Coverage typically has a waiting period, so buying after a forecast is too late. |
| Earthquake | Excluded. Shake damage is not covered. | A standalone earthquake policy or endorsement (e.g. the CEA in California). | Deductibles are percentage-based and can be large, so the policy mainly protects against a total or major loss. |
The practical takeaway: if your report flags flood or earthquake, coverage is a separate purchase you have to make on purpose. If it flags wildfire, the question is less "am I covered" and more "can I keep affordable coverage here." Our guide to disaster risk and home insurance goes deeper on each.
Broadly: flood touches nearly every state, with the heaviest exposure along coasts, major rivers, and low-lying urban areas. Wildfire concentrates across the interior and coastal West, the Southwest, and increasingly the Southeast, wherever development meets dry, burnable land. Earthquake is dominated by the West Coast fault systems, with additional seismic zones such as the New Madrid area in the central US. Because these patterns overlap unevenly, two homes in the same state can have very different profiles. Our natural disaster risk by state guide shows the state-level picture; the address report shows yours.
The one-line version: flood and earthquake are on you to insure separately, wildfire is covered until it makes you hard to insure, and all three depend far more on your exact location than on your state's reputation. Check the individual hazard ratings before you assume.
Your Disaster Risk Report rates all three (and 15 other hazards) for the census tract your address sits in, on FEMA's five-tier scale from Very Low to Very High. The hazards that rate highest for your location are pulled to the top so the signal is easy to read. To interpret the tiers, see understanding your hazard ratings, and for how the underlying score is built, see the methodology.
