The purpose of the Pacific Northwest Wildfire Hazard Assessment (PNRA) is to provide foundational information about wildfire hazard across the Pacific Northwest Region (which encompasses the states of Oregon and Washington). Such information supports both wildfire and vegetation management planning and provides a defensible, robust suite of analytics that are used by numerous partners across Oregon and Washington. The PNRA modeling provides spatially resolved information about wildfire likelihood and intensity across the Region. The results of this hazard assessment can be used to update the previously completed Quantitative Wildfire Risk Assessment (QWRA). A QWRA considers several different components, each resolved spatially across the region,
including:
• likelihood of a fire burning, • the intensity of a fire if one should occur,
• the exposure of assets and resources based on their locations, and • the susceptibility of those assets and resources
