Which hazard drives modeled loss here?

FEMA's modeled annual dollar loss for Sanders County is led by Riverine Flooding (about $5.8M Expected Annual Loss, Historical Loss Ratio Relatively High), while Landslide carries the highest National Risk Index rating (Relatively Moderate). EAL and risk score use different inputs; they need not agree.

What does Sanders County's hazard record show?

FEMA National Risk Index

FEMA's data shows an elevated National Risk Index composite of 47.4/100 for this county (Relatively Low rating). Expected Annual Loss comes in at Very Low (roughly $9.0M in annualized losses). Social vulnerability (Very High) and community resilience (Very Low) both factor into how that raw exposure plays out on the ground. Among the 18 modeled hazards, Landslide carries the county's highest rating, a mid-range Relatively Moderate. FEMA's modeled frequency puts that hazard at an average of 2.2 times per year here.

Reading the federal records together

This county has a small entry in FEMA's NFIP paid-claims table: 9 claims and $223.0K paid in total. PlainHazard calls 1-49 claims a light registry record, a label for this dataset rather than a finding that flood exposure is low. A short claims history can also reflect insurance take-up, the period covered, or losses that were never insured.

The declaration register points in the busier direction. Sanders County's 16 federal records stand 46% above the Montana county mean of 11.0. 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.

How often does each hazard strike Sanders 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.

Hazard NRI Risk Rating Recurrence
Landslide Relatively Moderate an average of 2.2 times per year
Wildfire Relatively Moderate roughly once every 591 years
Winter Weather Relatively High an average of 44 times per year
Ice Storm Relatively Moderate roughly once every 5 years
Earthquake Relatively Low roughly once every 49 years
Avalanche Relatively Low roughly once every 30 years
Cold Wave Relatively Moderate an average of 2.5 times per year
Riverine Flooding Relatively Low roughly once every 1 years
Heat Wave Very Low 2.1 modeled event-days per year

What Fire declarations mean here

Fire is the most frequent declaration type on Sanders County's record, 38% of its declarations. Wildfire is the one hazard here with its own dedicated federal instrument: the Fire Management Assistance Grant, which appears in this data as an FM record. An FMAG can be authorised while a fire is still burning, on a timescale of hours, because its purpose is to reimburse the cost of fighting a fire that threatens to become a major disaster.

That distinction matters when comparing counties. An FM declaration is not a presidential major disaster declaration and does not carry the same assistance programmes, so a fire-heavy county's total is not directly comparable with a hurricane-heavy county's total unless the declaration types are separated, which is why they are listed separately on this page.

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 Sanders County: the model and the federal record do NOT point at the same hazard. Landslide carries the highest modeled rating (Relatively Moderate), while the county's declaration history is led by Fire. 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

Sanders County's closest FEMA peer: Camp County, TX

Comparisons use published FEMA declaration fields plus the National Risk Index composite for Sanders 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.
