About Threat and Hazard Identification and Risk Assessment

The Threat and Hazard Identification and Risk Assessment (THIRA) is a 4 step common risk assessment process that helps the whole community—including individuals, businesses, faith-based organizations, nonprofit groups, schools and academia and all levels of government—understand its risks and estimate capability requirements. The THIRA process helps communities map their risks to the core capabilities, enabling them to determine whole-community informed:

  • Desired outcomes,
  • Capability targets, and
  • Resources required to achieve their Capability targets

The outputs of this process inform a variety of emergency management efforts, including: emergency operations planning, mutual aid agreements, and hazard mitigation planning. Ultimately, the THIRA process helps communities answer the following questions:

  • What do we need to prepare for?
  • What shareable resources are required in order to be prepared?

What actions could be employed to avoid, divert, lessen, or eliminate a threat or hazard?

Comprehensive Preparedness Guide 201, Second Edition

Comprehensive Preparedness Guide (CPG) 201, Second Edition released August 2013, provides communities additional guidance for conducting a THIRA. The first edition of this guide, released in April 2012, presented the basic steps of the THIRA process. Specifically, the first edition described 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.

CPG 201, Second Edition expands the THIRA process to include estimation of resources needed to meet the capability targets. The second edition also reflects other changes to the THIRA process based on stakeholder feedback and supersedes the first edition of CPG 201.
