In order to help communities understand and prepare for the various hazards that could impact their people, infrastructure, and economies, FEMA has developed a risk assessment process to identify and determine their level of vulnerability to these risks. FEMA’s Threat and Hazard Identification and Risk Assessment (THIRA) is a three-step risk assessment process that helps states, tribes, territories, and local communities answer the following questions: What threats and hazards can affect our community? If they occurred, what impacts would those threats and hazards have on our community? Based on those impacts, what capabilities should our community have?
