FEMA models no building damage here
Coastal floodingAvalanchesTsunamisVolcanic activity
People, not buildings.Counting harm to people as well as buildings, FEMA’s model puts cold waves at 10% of Patterson’s expected losses. Cold waves do little damage to buildings (0.0%), so they aren’t part of the grade.

Shares are of FEMA’s expected building damage, the measure the grade uses; ranks compare each hazard’s building-damage rate with all 85,154 U.S. census tracts. In FEMA’s terms, river and rain flooding is FEMA’s “Inland Flooding” (rivers and streams overflowing their banks, or rain overwhelming drainage). FEMA defines coastal flooding as high or rising tides and storm surge, so surge damage is counted there. Drought isn’t listed: FEMA counts its losses in crops only.

Flood risk changes street by street. Check a specific address on FEMA’s flood map, and ask about flood insurance before you buy.
