The Threat and Hazard Identification and Risk Assessment (THIRA) is a comprehensive risk assessment process developed by FEMA to help communities understand and address their unique risks.
THIRA is a systematic process to identify potential threats and hazards that could impact a community, assess their potential consequences, and determine the necessary capabilities to respond and recover. By understanding these risks, communities can develop effective emergency plans and build resilience. It also includes the process of quantifying and characterizing the threats to humans, property, and the environment.
THIRA helps communities prioritize resources, make informed decisions, and strengthen preparedness efforts. Whether you are a community, county, regional authority, or a state, understanding risk, especially as it relates to natural and manmade hazards, is a critical element of any emergency management program.
