The verdict

Two federal records point in the busier direction for Thurston County. Its 30 FEMA declarations are 21% above the Washington county mean and exceed the count for 86% of the 3,266 counties in this registry. Separately, FEMA's National Risk Index places it in the riskiest 6%, based on modeled expected annual loss, social vulnerability, and community resilience.

Which hazard drives modeled loss here?

FEMA's modeled annual dollar loss for Thurston County is led by Earthquake (about $133.7M Expected Annual Loss, Historical Loss Ratio Very High), while Landslide carries the highest National Risk Index rating (Relatively High). EAL and risk score use different inputs; they need not agree.

What does Thurston County's hazard record show?

Reading the federal records together

The NFIP claims register shows a middle-volume loss record here: 387 paid claims, totaling $6.5M. PlainHazard uses 50-499 claims for this descriptive band; FEMA does not publish it as a safety or coverage category. The $16.8K average describes payments on recorded claims only, leaving uninsured damage and properties without a claim outside the measure.

The declaration register points in the busier direction. Thurston County's 30 federal records stand 21% above the Washington county mean of 24.9. That comparison describes how often federal action was recorded, including any Major Disaster, Emergency, and Fire Management entries shown on this page; it does not convert the count into future probability.

FEMA National Risk Index

This county sits among the highest-risk counties nationally on FEMA's National Risk Index, a composite score of 94.5/100 (Relatively High). Expected Annual Loss is rated Relatively High (roughly $190.6M in annualized losses). Social vulnerability reads Very Low and community resilience Relatively High, both critical modifiers of realized harm here. Of the 18 hazards FEMA models, Landslide stands out as the sharpest exposure here, rated Relatively High. FEMA's modeled frequency puts that hazard at an average of 5.1 times per year here.

How often does each hazard strike Thurston County?

FEMA's National Risk Index models a historical event count and an annualized frequency for each hazard type. Most hazards are expressed as modeled occurrences per year; FEMA expresses drought and heat-wave frequency as event-days per year. These modeled frequencies are not forecasts.

Earthquake Relatively High roughly once every 33 years
Volcanic Activity Relatively Moderate roughly once every 88 years

What Flood declarations mean here

Flood is the most frequent declaration type on Thurston County's record, 47% of its declarations. Federal flood declarations cover two mechanisms that behave very differently: riverine flooding, which builds over days as a watershed drains and is usually forecast well in advance, and flash flooding, which can arrive in under an hour from rainfall that fell somewhere upstream.

Flood is also the one hazard class where a second federal dataset exists for the same events. The National Flood Insurance Program records what was actually paid on insured losses, so it measures a narrower thing than the declaration count: uninsured damage, and flooding outside mapped special flood hazard areas, never enters it. Reading the two together is more informative than either alone.

Declaration counts describe past federal action. They are a record of what was declared, not a forecast of future hazard probability.

The model's sharpest exposure here: Landslide

Landslide risk is a function of slope, soil and water, so it is usually a SECOND-ORDER hazard: it is triggered by the rainfall, snowmelt, wildfire burn scars or seismic shaking that came first. That is why a county can carry high landslide exposure whose realized damage is recorded under a flood or storm declaration instead.

Worth noting for Thurston County: the model and the federal record do NOT point at the same hazard. Landslide carries the highest modeled rating (Relatively High), while the county's declaration history is led by Flood. That is not a contradiction, the two measure genuinely different things. Declarations record federal ACTION, which requires damage costly enough to exceed state and local capacity; the Risk Index models EXPECTED annual loss across all 18 hazards whether or not any declaration ever followed. A hazard can be the county's largest modeled exposure and never once have driven a declaration.

National Risk Index ratings are modeled estimates of expected annual loss, not predictions of what will happen in any given year.

Data-matched county comparisons

Thurston County's closest FEMA peer: Essex County, VT

Comparisons use published FEMA declaration fields plus the National Risk Index composite for Thurston County. Record similarity, not a safety rating.

How these peers are chosen

Cohort: Published U.S. county equivalents outside the source state or territory. Each metric keeps six ETL candidates; three unique destinations are shown after de-duplicating across axes. Declaration-volume ranking combines count and Major-disaster share and prefers a different leading incident type; Major-share ranks the Major fraction adjusted for volume; NRI ranks the modeled composite score only.

The most active year for disaster declarations in Thurston County was 2020, with 4 declarations. The county has FEMA disaster data spanning 1965 to 2026.
What is the FEMA National Risk Index score for Thurston County?
According to the FEMA National Risk Index, Thurston County, Washington has an overall risk score of 94.5 out of 100 (Relatively High). Social vulnerability here rates Very Low, while community resilience comes in at Relatively High. The Expected Annual Loss (EAL) score is Relatively High, representing $190.6M in annualized losses.
Which natural hazard poses the greatest risk to Thurston County?
Based on FEMA NRI data, the highest-risk natural hazard in Thurston County is Landslide (risk rating: Relatively High). Other significant hazards include Earthquake (Relatively High) and Volcanic Activity (Relatively Moderate). FEMA's modeled event frequency puts landslide here at an average of 5.1 times per year.

Data Sources & Methodology

Disaster declaration data comes from the FEMA OpenFEMA Disaster Declarations Summaries v2 API, which includes all federally declared disasters, emergencies, and fire management assistance grants.
