This page is about how communities at risk of natural hazards would be affected.

Relevant variables for this topic include expected annual loss, social vulnerability, and community resilience.


The National Risk Index
Designed and built by the Federal Emergency Management Agency (FEMA), the National Risk Index is a dataset and interactive online tool that identifies communities that are most at risk for 18 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. The index uses factors such social vulnerability, expected annual losses, and community resilience to demonstrate how communities at risk of natural hazards would be affected. Local, regional, state, and federal planners, emergency managers, and decision-makers can use the National Risk Index to develop prevention strategies and emergency response plans for communities most at risk. This tool informs decision-makers and the public on communities most affected by hazards and can help prioritize projects that can ease suffering and disaster cost. [url; FEMA]
