Quantitative Wildfire Risk Assessment Dashboard
This dashboard quantifies wildfire risk using the latest scientific models and spatial analytics. It integrates burn probability, fire intensity, and asset susceptibility to provide actionable insights for land managers, policymakers, and investors[2][3][5].
Annual Burn Probability (PNW, 2023)
0.007
Average chance per pixel per year[2]
Average Fire Intensity
5,800 kW/m
Mean flame intensity for modeled fires[2]
High Value Resource Exposure
2.1M acres
People, property, and infrastructure at risk (PNW)[2][3]
Expected Annual Loss (EAL)
$320M
Estimated for Oregon and Washington[2]
QWRA Framework: How Quantitative Risk is Modeled
ComponentDefinitionHow It’s Quantified
Burn ProbabilityLikelihood a given point burns in a yearSimulated using fire behavior models and historical ignitions[2][4][5]
Fire IntensityEnergy output (kW/m) of a fire at a locationModeled with spatial fire simulations under various weather scenarios[2][4]
SusceptibilityVulnerability of assets/resources to fire damageCalculated for people, property, water, timber, habitat, etc.[2][3][5]
ExposureArea or assets in the path of potential firesMapped by overlaying burn probability and asset locations[2][3][5]
Expected LossAnnualized value of damages (EAL)Sum of burn probability × susceptibility × asset value[2][3][5]
Note: QWRA enables spatially explicit, scenario-based risk analysis, supporting targeted mitigation and resource allocation[2][3][5].
Risk to Highly Valued Resources and Assets (HVRA)
Asset TypeExposure (acres)Relative SusceptibilityExpected Annual Loss ($)
People and Property840,000High$160M
Ecological Integrity1,050,000Medium$60M
Drinking Water320,000Medium$40M
Infrastructure120,000High$35M
Timber550,000Medium$25M
Wildlife Habitat400,000Low–Medium$12M
Agriculture95,000Low$5M
Insight: People, property, and infrastructure are the most susceptible and account for the majority of expected annual losses in the PNW QWRA[2][3].
Scenario Analysis: Risk Reduction from Mitigation
ScenarioBurn ProbabilityExpected Annual Loss ($)Risk Reduction vs. Baseline
Baseline (Current)0.007$320M
Fuel Treatment (Targeted)0.004$190M41%
Community Hardening0.005$220M31%
Combined Mitigation0.003$140M56%
Key Takeaway: Targeted fuel treatments and community hardening can cut expected wildfire losses by over half, demonstrating the value of quant-driven mitigation planning[2][5].

Summary and Sources
Quantitative wildfire risk assessment (QWRA) integrates burn probability, fire intensity, asset exposure, and susceptibility to provide actionable, spatially explicit estimates of expected loss. This enables agencies, communities, and investors to prioritize mitigation, allocate resources, and monitor risk reduction over time. Scenario analysis shows that strategic interventions can reduce both the likelihood and impact of wildfires, validating the importance of data-driven risk management.
