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) from 1960 to present.
The most recent update of the data occurred on November 20, 2020 with the release of Version 19.0. This latest version includes data for 2019, substantially uploaded loss information for the 2000s, and expanded temporal coverage for the US territories (2000 through 2019). For more information see the SHELDUS Metadata.
Since the release of Version 15.2, the database includes insured crop losses (indemnity payments). Insured crop losses cover the period from January 1989 to present. Since the relase of Version 18.1, the database now contains loss information for Puerto Rico, Guam, and other U.S. territories.
SHELDUS™ was developed by the Hazards and Vulnerability Research Institute at the University of South Carolina and originally supported by grants from the National Science Foundation (Grant No. 99053252 and 0220712) and the University of South Carolina's Office of the Vice President for Research. Since 2018, the ASU Center for Emergency Management and Homeland Security supports and maintains SHELDUS™.
