Service Description: <p>The National Risk Index Counties - Natural Hazard Frequency (October 2020) map service contains county-level Natural Hazard Frequency data.</p><p>The National Risk Index (NRI) is an online tool to help illustrate the nation’s communities most at risk of natural hazards. It leverages authoritative nationwide datasets and multiplies values for exposure, hazard frequency, and historic loss ratios to derive Expected Annual Loss for 18 natural hazards; and it combines this metric with Social Vulnerability and Community Resilience data to generate a unitless, normalized Risk Index score for every census tract and county in the United States.</p><p>The NRI incorporates data for the following natural hazards: Avalanche, Coastal Flooding, Cold Wave, Drought, Earthquake, Hail, Heat Wave, Hurricane, Ice Storm, Landslide, Lightning, Riverine Flooding, Strong Wind, Tornado, Tsunami, Volcanic Activity, Wildfire, and Winter Weather.</p><p>Sources for Expected Annual Loss data include Arizona State University's Center for Emergency Management and Homeland Security, CoreLogic, Federal Emergency Management Agency (FEMA), Iowa State University, National Aeronautics and Space Administration (NASA), National Avalanche Center, National Oceanic and Atmospheric Administration (NOAA), NOAA National Hurricane Center (NHC), NOAA National Weather Service (NWS), NOAA Storm Prediction Center (SPC), NOAA / Vaisala National Lightning Detection Network (NLDN), Smithsonian Institution, State of Alaska, State of California, State of Hawaii, State of Oregon, State of Washington, United Nations Office for Disaster Risk Reduction, University of Nebraska-Lincoln, US Army Corps of Engineers (USACE), US Department of Agriculture (USDA), USDA Forest Service, and United States Geological Survey (USGS). Data for Social Vulnerability and Community Resilience is provided by University of South Carolina's Hazards & Vulnerability Research Institute (HVRI).</p><p><font size='4'>Get the intended user experience at <a href='https://tiny.cc/nri-data' target='_blank'>The National Risk Index application</a></font></p>
