How common are Terrorist disasters in the U.S.?

With so few declarations on record, the year-by-year pattern is necessarily sparse. The peak year on record was 2001, with 1 terrorist declarations issued that single year, a clustering driven by major multi-state events and the federal government's declaration cadence. The most recent year on record is 2013, with 1 declarations. Trends over the 12+ year history reflect how infrequently this disaster type crosses the federal declaration threshold at all.

FEMA has issued 2 federal disaster declarations classified as terrorist between 2001 and 2013, affecting 2 states and territories. Each declaration represents a formal federal recognition that an event exceeded state and local response capacity, unlocking Public Assistance, Individual Assistance, or Hazard Mitigation Grant Program funding depending on the declaration class (DR, EM, or FM). Raw declaration counts therefore measure the federal response footprint, which is a lagging and thresholded indicator: smaller events handled entirely at the state level never appear, and declaration thresholds have been recalibrated over the dataset's multi-decade history.

This disaster type's footprint is thin and scattered across the map. The three states with the most terrorist declarations on record are MA (1 declarations), VA (1 declarations), consistent with how narrowly this hazard type is geographically concentrated.

What is actually in FEMA's terrorist file?

The complete OpenFEMA record is small enough to inspect title by title: 2 declaration rows resolve to 2 named records. A row is a federal administrative action, not necessarily a separate physical event.

  • EXPLOSIONS: Massachusetts; Emergency (EM); 2013-04-17.
  • FIRES AND EXPLOSIONS: Virginia; Major Disaster (DR); 2001-09-21.

Every title in this category appears once in the current extract, so its declaration-row count and named-record count happen to match.

Which federal declaration does terrorist actually get?

With only 2 declarations on record, this type is too thin to express as a reliable percentage split, so the raw breakdown is: 1 Emergency (EM), 1 Major Disaster (DR). Each federal instrument carries different assistance: a Major Disaster declaration can unlock Individual Assistance and Hazard Mitigation funding, an Emergency declaration is narrower and faster, and Fire Management Assistance covers firefighting costs during an active incident.

What this means for Terrorist declarations

Terrorist is rarer than 96% of the other declaration types FEMA tracks, with 2 FEMA declaration records; Massachusetts leads with 1.

A federal declaration is a legal assistance trigger, not a count of every storm event or a forecast. For current threats follow the National Weather Service and local officials; in an emergency call 911.
