Ranking reflects the count of Presidentially declared federal disasters per OpenFEMA, not event severity or economic loss; a rare declaration type can still be individually catastrophic.

OpenFEMA mud/landslide declaration counts by year. Focus a year mark for its exact count.

Peak year in this series: 2014 (2 declarations). A declaration is a federal assistance trigger, not a raw event count.

How common are Mud/Landslide disasters in the U.S.?

FEMA has issued 13 federal disaster declarations classified as mud/landslide between 1973 and 2025, affecting 7 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.

With so few declarations on record, the year-by-year pattern is necessarily sparse. The peak year on record was 2014, with 2 mud/landslide 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 2025, with 1 declarations. Trends over the 52+ year history reflect how infrequently this disaster type crosses the federal declaration threshold at all.

This disaster type's footprint is thin and scattered across the map. The three states with the most mud/landslide declarations on record are AK (5 declarations), WA (3 declarations), HI (1 declarations), consistent with how narrowly this hazard type is geographically concentrated. States with the fewest declarations, including OH (1), OR (1), WV (1), unsurprising given how rare a federal declaration of this type is anywhere in the country.

Which federal declaration does mud/landslide actually get?

This is a conventional Major Disaster type: 92% of its 13 declarations are DRs, with 8% filed as Emergencies. A DR is the instrument that opens the widest set of programs -- Public Assistance for damaged infrastructure, Individual Assistance for households, and Hazard Mitigation funding intended to reduce the next event's cost. The concentration means these events are typically declared after damage has been assessed, not while they are still developing.

What this means for Mud/Landslide declarations

Mud/Landslide is rarer than 62% of the other declaration types FEMA tracks, with 13 FEMA declaration records; Alaska leads with 5.

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.
