Which hazard drives modeled loss here?

FEMA's modeled annual dollar loss for Muskingum County is led by Riverine Flooding (about $23.6M 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 Muskingum County's hazard record show?

Reading the federal records together

The NFIP claims register shows a middle-volume loss record here: 174 paid claims, totaling $2.2M. PlainHazard uses 50-499 claims for this descriptive band; FEMA does not publish it as a safety or coverage category. The $12.5K 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. Muskingum County's 17 federal records stand 16% above the Ohio county mean of 14.6. 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 carries a high composite score on FEMA's National Risk Index, 70.9/100, rated Relatively Low. Its Expected Annual Loss rating is Relatively Low (roughly $29.4M in annualized losses), and a Relatively Moderate social-vulnerability profile combined with Relatively High community resilience shapes how much of that raw exposure becomes realized harm. 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 1.2 times per year here.

Declaration frequency

The FEMA register is busy by both local and national comparisons. It contains 17 entries for Muskingum County, including 12 Major Disaster records, 16% above the Ohio county mean. Across the 51-year span, that works out to 0.3 declarations a year. Severe Storm leads the file with 7 entries. Declaration type records the federal action taken, not every assistance program approved.

How often does each hazard strike Muskingum 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 1.2 times per year
Riverine Flooding Relatively Moderate an average of 2 times per year
Hail Relatively Moderate an average of 3.1 times per year
Ice Storm Relatively Moderate roughly once every 2 years
Lightning Relatively Moderate an average of 44 times per year
Drought Relatively Moderate 5.6 modeled event-days per year
Winter Weather Relatively Moderate an average of 9 times per year
Heat Wave Relatively Low 2.3 modeled event-days per year
Strong Wind Relatively Moderate an average of 1.6 times per year
Tornado Relatively Low roughly once every 4 years
Earthquake Very Low roughly once every 1,357 years
Hurricane Very Low roughly once every 145 years
Wildfire Very Low roughly once every 13,187 years

What Severe Storm declarations mean here

Severe Storm is the most frequent declaration type on Muskingum County's record, 41% 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: 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 Muskingum 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-matched county comparisons

Muskingum County's closest FEMA peer: Adams County, WI

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

Which natural hazard poses the greatest risk to Muskingum County?
Based on FEMA NRI data, the highest-risk natural hazard in Muskingum County as of the latest release is Landslide (risk rating: Relatively Low). Other significant hazards include Riverine Flooding (Relatively Moderate) and Hail (Relatively Moderate). FEMA's modeled event frequency puts landslide here at an average of 1.2 times per year. The underlying methodology weighs historical event frequency against exposed assets and community vulnerability.
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 Muskingum County

Muskingum County, OH has 17 federal declaration records, 16% more than the Ohio county mean of 15; its history sits in PlainHazard's high activity band.

  • Within this above-state-average declaration file, major disaster leads with 12 of 17 records; the category describes past federal action, not the next likely hazard. Ohio overview
  • The state benchmark and national rank point the same way: this count tops the Ohio mean and the totals for 32% 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.
