Threat and Hazard Identification and Risk Assessment (THIRA)

Minnesota is among the state’s leading in the national effort to identify and prioritize risk to hometowns and determine the resources that jurisdiction has to reduce that risk.
The Threat and Hazard Identification and Risk Assessment (THIRA) process helps communities understand the normal set of risks it faces.  By identifying and prioritizing those threats, a community can then make smarter decisions. Leaders need to  manage the risks through
  • Appropriate planning
  • Mitigation strategies
  • Developing needed capabilities
Risk is the potential for an unwanted outcome resulting from an incident, event, or occurrence, as determined by its likelihood and the associated consequences. By considering changes to these elements, a community can understand how to best manage and plan for its greatest risks across the full range of the threats and hazards it faces.

The THIRA Process:

  1. Identify Threats and Hazards of Concern: Based on a combination of experience, forecasting, subject matter expertise, and other available resources, identify a list of the threats and hazards of primary concern to the community.
  2. Give the Threats and Hazards Context: Describe the threats and hazards of concern, showing how they may affect the community.
  3. Establish Capability Targets: Assess each threat and hazard in context to develop a specific capability target for each core capability identified in the National Preparedness Goal. The capability target defines success for the capability.
  4. Apply the Results: For each core capability, estimate the resources required to achieve the capability targets through the use of community assets and mutual aid, while also considering preparedness activities, including mitigation opportunities.


Comprehensive Preparedness Guide 201: Threat and Hazard Identification and Risk Assessment, Second Edition

The Comprehensive Preparedness Guide (CPG) 201, Second Edition provides communities additional guidance for conducting a Threat and Hazard Identification and Risk Assessment (THIRA). The First Edition of this Guide (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.

Minnesota Specific Validation Criteria

Each of our 87 counties, four cities of the first class and six Homeland Security and Emergency Management (HSEM) regions are required to develop and annually update a jurisdictionally-specific THIRA. Our 11 federally recognized tribal communities within Minnesota are also encouraged to participate in the THIRA development process.
THIRAs are due to HSEM annually on December 31. The checklist linked below (TBD) will be used to review each THIRA submitted to HSEM for validation.
