HazardMap
Federally declared disasters and earthquake history for every US state, from FEMA and USGS open data.
HazardMap tracks 5,192 federally declared disasters (69,936 declaration-county records) across the 51 US states and DC, from 1953 to 2026, using FEMA open data. For any state you can look up its total disaster declarations, its most common hazard, a breakdown by incident type and decade, and its most recent declarations. We also list the 200 largest US earthquakes (magnitude 6.0+) from USGS, plus reference tables for hurricane categories and FEMA flood zones.

2026-06-18 Understanding FEMA disaster declarationsWhat a FEMA disaster declaration is, the difference between Major Disaster (DR), Emergency (EM) and Fire Management (FM) declarations, and how the process works — explained with real US data.
2026-06-17 FEMA flood zones explained: A, AE, X, V and VEWhat FEMA flood-zone codes mean for your home and insurance. Zones A and AE are high-risk; V and VE are high-risk coastal; X is low-risk. Clear table plus what each means for mandatory flood insurance.
2026-06-16 Earthquake risk by region in the US (USGS data)Where the strongest US earthquakes happen. Alaska dominates the record — including the M9.2 1964 quake — followed by California and Hawaii. A region-by-region look at seismic risk using USGS data.
2026-06-15 What a disaster declaration means for homeowners and insuranceA FEMA disaster declaration can unlock grants and low-interest loans — but it does not replace insurance, and federal aid rarely covers full rebuilding. What a declaration does and doesn't do for homeowners.
2026-06-14 Hurricane categories explained (the Saffir-Simpson scale)What the 5 hurricane categories mean, from Category 1 (74 mph) to Category 5 (157+ mph). Why 'major' starts at Category 3, and why category alone understates the danger from water.

HazardMap publishes fast, free, answer-first reference data in the US natural-hazard and disaster reference data space. Disaster counts come from the OpenFEMA Disaster Declarations Summaries, and earthquake history from the USGS earthquake catalog — both US public domain. See our methodology for exactly how the figures are aggregated.
HazardMap presents factual public-data summaries for general information only. It is not safety, emergency, or insurance advice, and is not affiliated with or endorsed by FEMA or USGS. Verify risk and coverage with official sources.
