About PlainHazard

PlainHazard keeps the natural hazards record of every U.S. county and state (storms, floods, fires and the disasters FEMA declared), from NOAA's and FEMA's own files, and works out what no single file shows: how a place ranks, when its hazards strike, and what they have cost. It is published by PlainHazard and owned by Kiznis Studio.

What PlainHazard publishes

A page for each of 3,266 counties and county equivalents and for every state, DC and territory, built from 2,004,972 storm events NOAA recorded from 1950 through June 30, 2026, 73,458 tornadoes in the Storm Prediction Center's database and FEMA's 5,269 disaster declarations since 1953, with FEMA's flood insurance claims and its National Risk Index beside them.

On top of the files, PlainHazard places zone-filed storm records on the counties they covered, converts damage to 2025 dollars, ranks every county and state against the others per square mile and per person, and publishes records and analyses of the whole record, each with its method and limits.

What it is not

  • It is not a warning service. For a storm happening now, follow your local National Weather Service office and local officials.
  • It is not an insurance, property or safety assessment. A county's record and FEMA's model rating describe the county, not a particular building or street.
  • It is not a government site. PlainHazard is independent and is not affiliated with NOAA, FEMA or any agency it cites.
  • It is not professional advice of any kind; the disclaimer sets out what to check before relying on a figure.

Who answers for it

The owner is Kiznis Studio, based in Lithuania. Kiznis Studio uses AI tools to write PlainHazard's code, its page templates and the wording of its guides and analyses. The tools do not generate figures: every count, rank and dollar amount is a query over the federal files, or is quoted from the agency's own pages (saved copies, credited), and each analysis prints how it was measured. PlainHazard Editorial, the desk at Kiznis Studio that publishes PlainHazard, answers for what it prints.
