<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> |

<p>The National Risk Index (NRI) and its associated data are meant for planning purposes only. This tool was created for broad nationwide comparisons and is not a substitute for localized risk assessment analysis. Nationwide datasets used as inputs for the NRI are, in many cases, not as accurate as available local data. Users with access to local data for each NRI risk factor should consider substituting the NRI data with local data to recalculate a more accurate risk index. If you decide to download the NRI data and substitute it with local data, you assume responsibility for the accuracy of the data and any resulting data index.</p><p>The methodology used by the NRI has been reviewed by subject matter experts in the fields of natural hazard risk research, risk analysis, mitigation planning, and emergency management. The processing methods used to create the NRI have produced results similar to those from other natural hazard risk analyses conducted on a smaller scale. The breadth and combination of Geographic Information Systems (GIS) and data processing techniques leveraged by the NRI enable it to incorporate multiple hazards and risk factors, manage its nationwide scope, and capture what might have been missed using other methods.</p><p>The NRI does not consider the intricate economic and physical interdependencies that exist across geographic regions. Keep in mind that hazard impacts in surrounding counties or census tracts can cause indirect losses in your location regardless of your location's risk profile.</p><p>Nationwide data available for some risk factors are rudimentary at this time. The NRI will be continuously updated as new data becomes available and improved methodologies are identified.</p><p>Email <a href='mailto:FEMA-NRI@fema.dhs.gov' target='_blank'>FEMA-NRI@fema.dhs.gov</a> to request a draft copy of the NRI Technical Document, which provides comprehensive details about how the NRI can help you and its limitations.</p> |
