Which hazard drives modeled loss here?

FEMA's modeled annual dollar loss for Franklin County is led by Riverine Flooding (about $26.0M Expected Annual Loss, Historical Loss Ratio Relatively Moderate), while Hurricane carries the highest National Risk Index rating (Relatively Moderate). EAL and risk score use different inputs; they need not agree.

What does Franklin County's hazard record show?

Reading the federal records together

The NFIP claims register shows a middle-volume loss record here: 188 paid claims, totaling $1.1M. PlainHazard uses 50-499 claims for this descriptive band; FEMA does not publish it as a safety or coverage category. The $5.7K 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. Franklin County's 20 federal records stand 8% above the Pennsylvania county mean of 18.6. 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 76.4/100 (Relatively Low). Expected Annual Loss is rated Relatively Low (roughly $37.7M in annualized losses). Social vulnerability reads Relatively Low and community resilience Relatively High, both critical modifiers of realized harm here. Among the 18 modeled hazards, Hurricane carries the county's highest rating, a mid-range Relatively Moderate. FEMA's modeled frequency puts that hazard at roughly once every 14 years here, based on 22 historical events on record.

Declaration frequency

The FEMA register is busy by both local and national comparisons. It contains 20 entries for Franklin County, including 14 Major Disaster records, 8% above the Pennsylvania county mean. Across the 48-year span, that works out to 0.4 declarations a year. Flood leads the file with 6 entries. Declaration type records the federal action taken, not every assistance program approved.

How often does each hazard strike Franklin 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
Hurricane Relatively Moderate roughly once every 14 years
Riverine Flooding Relatively Moderate an average of 1.9 times per year
Strong Wind Relatively Moderate an average of 5.3 times per year
Winter Weather Relatively Moderate an average of 12 times per year
Drought Relatively Moderate 0.9 modeled event-days per year
Landslide Relatively Low roughly once every 2 years
Earthquake Relatively Low roughly once every 1,019 years
Heat Wave Relatively Low 4.3 modeled event-days per year
Lightning Relatively Moderate an average of 37 times per year
Hail Relatively Low an average of 2.7 times per year
Wildfire Very Low roughly once every 11,891 years

What Flood declarations mean here

Flood is the most frequent declaration type on Franklin County's record, 30% 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: Hurricane

Hurricane exposure in the model bundles the three ways a tropical system does harm, which arrive on different timescales and are insured differently: wind, storm surge on the coast, and rainfall flooding that can reach far inland well after landfall.

Worth noting for Franklin County: the model and the federal record do NOT point at the same hazard. Hurricane 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.

Data-matched county comparisons

Franklin County's closest FEMA peer: Barbour County, WV

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

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 Franklin County

Franklin County, PA has 20 federal declaration records, 8% more than the Pennsylvania county mean of 19; its history sits in PlainHazard's high activity band.

  • Within this above-state-average declaration file, major disaster leads with 14 of 20 records; the category describes past federal action, not the next likely hazard. Pennsylvania overview
  • The state benchmark and national rank point the same way: this count tops the Pennsylvania mean and the totals for 46% of 3,266 U.S. counties. Most-disaster rankings
  • Use the data guide to separate this mid-volume insurance-claims file from declaration counts and modeled NRI risk. Disaster-data guide

An above-average declaration count records past federal responses; it does not predict the next event. Current warnings come from the National Weather Service and local emergency officials.
