This polygon dataset shows severe storms/thunderstorms in the United States for 1995 to 2000.This data set is a subset of the Spatial Hazard Events and Losses Database for the United States (SHELDUS Version 2.0) that was compiled by the University of South Carolina. It portrays county-level hazard data for the United States, for the years 1995 to 2000. Included is information for 16 different natural hazard event types, as well as the total cost of damage due to natural hazards. The event types included are avalanches, coastal events, drought, flooding, fog, hail, heat, hurricanes/tropical storms, landslides, lightning, severe storms/thunderstorms, tornadoes, tsunamis/seiches, wildfires, wind, and winter weather. For each event type, information is reported on property losses, crop losses, injuries, and fatalities in each county.
The hazards information was derived from several existing national data sources such as the National Climatic Data Center's (NCDC) monthly Storm Data publications and the National Geophysical Data Center's Tsunami Event Database. Included are those events that generated more than $50,000 in damages, and events that are reported in NCDC's Storm Data with a specific damage amount.
This is an update of the August, 2004, data set. A field containing information on property damage per square mile has been added to the total damages file.
