About Threat and Hazard Identification and Risk Assessment

The Threat and Hazard Identification and Risk Assessment (THIRA) is a three-step risk assessment process that helps 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?

The THIRA helps communities understand their risks and determine the level of capability they need in order to address those risks. The outputs form this process lay the foundation for determining a community’s capability gaps as part of the Stakeholder Preparedness Review.

Comprehensive Preparedness Guide 201, Third Edition

Comprehensive Preparedness Guide (CPG) 201, Third Edition provides guidance for conducting a Threat and Hazard Identification and Risk Assessment (THIRA) and Stakeholder Preparedness Review (SPR), formerly State Preparedness Report. The First Edition of CPG 201 (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 targets for each core capability identified in the National Preparedness Goal. The Second Edition expanded the THIRA process, streamlined the number of steps in the process, and provided additional examples of how to develop a THIRA assessment.

CPG 201, Third Edition expands to include both the THIRA and SPR because they are interconnected processes that, together, communities use to evaluate their preparedness. This Edition also introduces updates to both methodologies. The updated THIRA adopts standardized language to describe impacts and targets and allows communities to collect more specific, quantitative information while also providing important context.

Where appropriate, this Edition highlights key changes from previous editions of CPG 201. This Third Edition supersedes the Second Edition of CPG 201.


FEMA is updating its resources to help jurisdictions understand the THIRA process and will post them here when they are available.
