SHELDUS™ is a county-level hazard data set for the U.S. and covers natural hazards such thunderstorms, hurricanes, floods, wildfires, and tornados as well as perils such as flash floods, heavy rainfall, etc. The database contains information on the date of an event, affected location (county and state) and the direct losses caused by the event (property and crop losses, injuries, and fatalities) as well as insured crop losses (indemnity payments by the U.S. Department of Agriculture). The data contained in SHELDUS™ draw heavily on multiple hazard databases housed under the umbrella of the National Centers for Environmental Information (NCEI) and the U.S. Department of Agriculture. All data are georeferenced at the county level and adjusted for county population as well as inflation.
The database covers the period from January 1960 to present and is updated annually. The database is searchable by location and time, presidentially declared disasters (PDD) , Billion Dollar Events (named events) , and Global Identifier Number (GLIDE) . For more information see the SHELDUS™ Metadata .

Since 2018, the ASU Center for Emergency Management and Homeland Security supports and maintains SHELDUS™.
