Frequently Asked Questions
- Where does the disaster history come from?
- Federal records: OpenFEMA for disaster declarations and assistance, NOAA Storm Events, USGS for earthquakes, and NIFC for wildfires. FEMA's declaration record runs back to 1953.
- Does a long disaster history mean a place is unsafe to live in?
- No. This is a record of what has happened, not a prediction. We always phrase it as counts over a period — 'N declarations since 1980' — and never as a judgment about living there.
- Are the assistance figures the cost of the disaster?
- No. They're the federal money obligated under specific aid programs. Total economic loss is a different, usually much larger, figure measured separately and not shown here.
- Where should I check for current threats?
- The National Weather Service and FEMA. This site is about history and statistics, not live conditions, and it links out to the official sources for anything current.
- Is DisasterAtlasUSA affiliated with FEMA or NOAA?
- No. It is an independent reference site built on public U.S. government data, not endorsed by or affiliated with any agency.
