Threat and Hazard Identification and Risk Assessment (THIRA)

The Threat and Hazard Identification and Risk Assessment (THIRA) is a risk assessment process that helps develop a shared understanding of risks, set regional performance outcomes and targets, and identify resource requirements aligned with the National Preparedness Goal’s 31 Core Capabilities. The annual THIRA update is one of many mechanisms by which the RDPO achieves its mission to build and maintain regional disaster preparedness capabilities in the Portland Urban Area (PUA) through strategic and coordinated planning, training and exercising, and investment.

Outputs of the THIRA process can inform a variety of disaster preparedness and emergency management efforts, including: strategic and program planning to better direct funding investments, emergency operations planning, mutual aid agreements, and hazard mitigation planning. Ultimately, the
THIRA process helps the RDPO and the associated whole community answer the following questions:

  • What do we need to prepare for at the regional level?
  • What capabilities should we build and can we maintain?
  • What regionally‐deployable resources are required to be prepared?
