The verdict
Greene County has a nationally busy FEMA history: 15 declarations, more than 23% of counties in this registry. But the state comparison tempers that reading: the total is 19% below the Pennsylvania county mean. FEMA's separate National Risk Index places the county in the riskiest 45%; that score models loss and vulnerability rather than counting declarations.

FEMA National Risk Index composite score vs. the Pennsylvania county average
Which hazard drives modeled loss here?
FEMA's modeled annual dollar loss for Greene County is led by Riverine Flooding (about $14.5M 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 Greene County's hazard record show?
Reading the federal records together
The NFIP claims register shows a middle-volume loss record here: 265 paid claims, totaling $3.5M. PlainHazard uses 50-499 claims for this descriptive band; FEMA does not publish it as a safety or coverage category. The $13.3K average describes payments on recorded claims only, leaving uninsured damage and properties without a claim outside the measure.
Start with the state benchmark: a Pennsylvania county averages 18.6 federal declaration records, while Greene County has 15. The gap is 19% below that mean. Fewer entries indicate a quieter history of recorded federal actions, not immunity from a hazard and not a prediction about what happens next.
FEMA National Risk Index
This county carries a high composite score on FEMA's National Risk Index, 55.1/100, rated Relatively Low. Its Expected Annual Loss rating is Relatively Low (roughly $17.0M in annualized losses), and a Relatively Moderate social-vulnerability profile combined with Relatively Moderate community resilience shapes how much of that raw exposure becomes realized harm. 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 1.4 times per year here.
Declaration frequency
Nationally, Greene County's 15 FEMA records form a high-volume history; within Pennsylvania, however, the count is 19% below the county mean. 10 entries carry the Major Disaster classification. The largest incident group is Flood, appearing 4 times. The full 48-year record averages 0.3 declarations annually. A DR label alone does not say whether Individual Assistance, Public Assistance, or both followed.

How often does each hazard strike Greene 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 1.4 times per year |
| Riverine Flooding | Relatively Moderate | an average of 1.9 times per year |
| Hurricane | Relatively Low | roughly once every 43 years |
| Hail | Relatively Low | an average of 2.9 times per year |
| Lightning | Relatively Low | an average of 43 times per year |
| Drought | Relatively Low | 1.5 modeled event-days per year |
| Earthquake | Very Low | roughly once every 2,105 years |
| Tornado | Relatively Low | roughly once every 7 years |
| Strong Wind | Relatively Low | an average of 2 times per year |
| Ice Storm | Relatively Low | roughly once every 3 years |
| Cold Wave | Relatively Low | an average of 2.6 times per year |

What Flood declarations mean here
Flood is the most frequent declaration type on Greene County's record, 27% 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 Greene 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 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.

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.

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 Greene County
Against a Pennsylvania county mean of 19 declarations, Greene County, PA records 15, or 19% fewer. PlainHazard classifies that historical total as high activity.
- Major Disaster is the largest group (10 of 15) in a declaration history that remains below its state benchmark; frequency here is not a forecast. Pennsylvania overview
