Natural-disaster risk in United States

In United States, the leading natural-disaster exposures are flooding, storms (hurricane/cyclone), wildfire. The safest city for disasters is Madison (safety 69/100). Risk is modelled from real USGS counts of magnitude-4.5+ earthquakes within 300 km since 1980 plus Köppen climate zones and cyclone/subduction geography.

What drives United States's disaster profile

Across the 38 United States cities in our data, the three highest average exposures are flooding (2.7/5), storms (hurricane/cyclone) (2.6/5) and wildfire (2.4/5). These reflect geography rather than chance: earthquake tiers come from real USGS records of magnitude-4.5+ events within 300 km, storm risk from position in a tropical-cyclone basin, flood from rainfall regime and low-lying terrain, and wildfire/heat from Köppen climate zone. The full modelled profile for United States is flooding 2.7/5; storms (hurricane/cyclone) 2.6/5; wildfire 2.4/5; extreme cold / winter 2.3/5; extreme heat 2.2/5; earthquake 2.0/5; drought 1.7/5; tsunami 1.1/5. Use it as a relative guide between cities — a high tier means plan for it (insurance, building codes, location within the city), not that disaster is certain. City pages break each hazard down individually.

United States disaster exposure by type

flooding: 2.7/5 — low — a minor consideration.
storms (hurricane/cyclone): 2.6/5 — low — a minor consideration.
wildfire: 2.4/5 — low — a minor consideration.
extreme cold / winter: 2.3/5 — low — a minor consideration.
extreme heat: 2.2/5 — low — a minor consideration.
earthquake: 2.0/5 — low — a minor consideration.
drought: 1.7/5 — negligible in our model.
tsunami: 1.1/5 — negligible in our model.

For relocators, the practical takeaway is to match the hazard profile to your housing choice: where flood or storm tiers are elevated, favour higher ground and modern drainage; where the earthquake tier is high, prioritise post-code seismic construction; and budget for the insurance lines that the leading hazards in United States will drive. The safest single city in our United States sample, Madison (safety 69/100), is the natural starting point if low disaster exposure is your top filter.
