The verdict
Two federal records point in the busier direction for Sullivan County. Its 33 FEMA declarations are 3% above the New Hampshire county mean and exceed the count for 91% of the 3,266 counties in this registry. Separately, FEMA's National Risk Index places it safer than 38%, based on modeled expected annual loss, social vulnerability, and community resilience.

FEMA National Risk Index composite score vs. the New Hampshire county average
Which hazard drives modeled loss here?
FEMA's modeled annual dollar loss for Sullivan County is led by Riverine Flooding (about $11.7M Expected Annual Loss, Historical Loss Ratio Relatively High), while Landslide 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?
Reading the federal records together
The NFIP claims register shows a middle-volume loss record here: 62 paid claims, totaling $1.3M. PlainHazard uses 50-499 claims for this descriptive band; FEMA does not publish it as a safety or coverage category. The $20.4K 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. Sullivan County's 33 federal records stand 3% above the New Hampshire county mean of 31.9. 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
FEMA's data shows an elevated National Risk Index composite of 37.6/100 for this county (Very Low rating). Expected Annual Loss comes in at Relatively Low (roughly $15.0M in annualized losses). Social vulnerability (Very Low) and community resilience (Relatively High) both factor into how that raw exposure plays out on the ground. Even the county's top-rated hazard, Landslide, 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 an average of 1.1 times per year here.
Declaration frequency
The FEMA register is busy by both local and national comparisons. It contains 33 entries for Sullivan County, including 22 Major Disaster records, 3% above the New Hampshire county mean. Across the 51-year span, that works out to 0.6 declarations a year. Severe Storm leads the file with 11 entries. Declaration type records the federal action taken, not every assistance program approved.

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 |
|---|---|---|
| Landslide | Relatively Low | an average of 1.1 times per year |
| Hurricane | Relatively Low | roughly once every 17 years |
| Ice Storm | Relatively Moderate | roughly once every 1 years |
| Riverine Flooding | Relatively Low | an average of 1.4 times per year |
| Lightning | Relatively Low | an average of 21 times per year |
| Winter Weather | Relatively Low | an average of 19 times per year |
| Heat Wave | Relatively Low | 2.1 modeled event-days per year |
| Earthquake | Very Low | roughly once every 804 years |
| Cold Wave | Relatively Low | an average of 2.1 times per year |

What Severe Storm declarations mean here
Severe Storm is the most frequent declaration type on Sullivan County's record, 33% 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.

Drought No Rating

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 Sullivan County: the model and the federal record do NOT point at the same hazard. Landslide 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 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.
Storm event data is sourced from the NOAA Storm Events Database (2015-2025), which tracks significant weather events including thunderstorms, tornadoes, floods, and winter storms.
Flood insurance data comes from the FEMA National Flood Insurance Program (NFIP) OpenFEMA claims dataset.
This data is provided for informational purposes only. FEMA disaster declarations represent federal response actions and may not capture all local emergencies or weather events.
What this means for Sullivan County
Sullivan County, NH has 33 federal declaration records, 3% more than the New Hampshire county mean of 32; its history sits in PlainHazard's high activity band.
- Within this above-state-average declaration file, major disaster leads with 22 of 33 records; the category describes past federal action, not the next likely hazard. New Hampshire overview
