  • National Risk Index
    The National Risk Index (NRI) is a new online resource from FEMA that analyzes risk factors for 18 natural hazards by defining risk as the product of expected annual loss (EAL), social vulnerability and community resilience.
  • Preliminary Flood Hazard Data
    Preliminary flood hazard data provide the public an early look at the projected risk to flood hazards. Preliminary data may include: new or revised Flood Insurance Rate Maps (FIRM), Flood Insurance Study (FIS) reports, and FIRM Databases.
  • National Flood Hazard Layer
    National Flood Hazard Layer is a geospatial database made from effective flood maps and Letters of Map Change (LOMC).
  • Hazus
    Hazus is a nationally available methodology that models potential losses from earthquakes/tsunamis, floods and hurricanes. Hazus uses GIS technology to estimate physical, economic and social impacts of these hazards.
