The verdict

Two federal records point in the busier direction for Sullivan County. Its 19 FEMA declarations are 11% above the Indiana county mean and exceed the count for 41% of the 3,266 counties in this registry. Separately, FEMA's National Risk Index places it safer than 21%, based on modeled expected annual loss, social vulnerability, and community resilience.

Which hazard drives modeled loss here?

FEMA's modeled annual dollar loss for Sullivan County is led by Riverine Flooding (about $2.9M Expected Annual Loss, Historical Loss Ratio Relatively High), while Earthquake carries the highest National Risk Index rating (Relatively Low). EAL and risk score use different inputs; they need not agree.

What does Sullivan County's hazard record show?

FEMA National Risk Index

This county's FEMA National Risk Index composite lands at 20.6/100 (Very Low), a modest reading against the rest of the country. Expected Annual Loss is rated Very Low (roughly $7.9M in annualized losses), tempered or compounded by a Relatively Low social-vulnerability score and Relatively High community-resilience score. Even the county's top-rated hazard, Earthquake, only reaches Relatively Low on FEMA's scale, none of the 18 modeled hazards stand out here. FEMA's modeled frequency puts that hazard at roughly once every 229 years here.

Reading the federal records together

This county has a small entry in FEMA's NFIP paid-claims table: 1 claim and $42.2K 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. Sullivan County's 19 federal records stand 11% above the Indiana county mean of 17.1. 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 Sullivan 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
Earthquake Relatively Low roughly once every 229 years
Drought Relatively Low 2.2 modeled event-days per year
Landslide Very Low roughly once every 4 years
Winter Weather Relatively Low an average of 7.6 times per year
Strong Wind Relatively Low an average of 4.3 times per year
Tornado Relatively Low roughly once every 3 years
Heat Wave Relatively Low 6.1 modeled event-days per year

What Severe Storm declarations mean here

Severe Storm is the most frequent declaration type on Sullivan County's record, 53% of its declarations. In FEMA's vocabulary this covers convective weather: thunderstorm straight-line winds, large hail, and the multi-day outbreaks that often carry embedded tornadoes. Activity is heaviest in spring and summer, though the season varies by region.

These events behave differently from a hurricane on paper. Damage tends to be distributed along a storm track rather than concentrated on a coastline, and a declaration typically follows an outbreak that crossed several counties over a few days, not a single point of impact. Because the qualifying threshold is the cost of uninsured public and individual losses rather than storm intensity, two similar storms can produce a declaration in one year and none in another.

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: Earthquake

Earthquake is the model's clearest example of a hazard with no season and no warning. Its expected loss is driven less by how often shaking occurs than by how much of the building stock predates modern seismic codes, so exposure can be high in places where nothing has happened for a long time.

Worth noting for Sullivan County: the model and the federal record do NOT point at the same hazard. Earthquake carries the highest modeled rating (Relatively Low), while the county's declaration history is led by Severe Storm. 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

Sullivan County's closest FEMA peer: Kings County, CA

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