FEMA Threat and Hazard Identification Risk Assessment (THIRA)

The U.S. Federal Emergency Management Agency’s (FEMA’s) Threat and Hazard Identification and Risk Assessment (THIRA) is a 4 step common risk assessment process that supports a community in understanding its natural hazard risks, and estimating capability requirements. The THIRA process helps communities map their risks to the core capabilities, enabling them to determine desired outcomes, capability targets, and the resources required to achieve their capability targets. 

The 4 step THIRA process is:

1. Identify Threats and Hazards of Concern
2. Give the Threats and Hazards Context
3. Establish Capability Targets
4. Apply the Results

The results of the THIRA process can inform a variety of emergency management efforts, including: emergency operations planning, mutual aid agreements, and hazard mitigation planning.

FEMA’s Comprehensive Preparedness Guide 201(CPG) provides communities guidance for conducting a THIRA. The first edition of this guide, released in April 2012, presented the basic steps of the THIRA process, describing a standard process for identifying community-specific threats and hazards and setting capability targets for each core capability identified in the National Preparedness Goal as required in Presidential Policy Directive (PPD) 8: National Preparedness.

The Second Edition 2013 CPG 201 expands the THIRA process to include estimation of resources needed to meet the capability targets. This guide can be found at: http://www.fema.gov/media-library/assets/documents/26335
