Hamilton County's FEMA Risk Index score
Which hazard drives modeled loss here?
FEMA's modeled annual dollar loss for Hamilton County is led by Riverine Flooding (about $72.8M Expected Annual Loss, Historical Loss Ratio Relatively High), while Tornado carries the highest National Risk Index rating (Relatively High). EAL and risk score use different inputs; they need not agree.

What does Hamilton County's hazard record show?
Reading the federal records together
The NFIP claims register shows a middle-volume loss record here: 418 paid claims, totaling $3.9M. PlainHazard uses 50-499 claims for this descriptive band; FEMA does not publish it as a safety or coverage category. The $9.3K 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. Hamilton 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.
FEMA National Risk Index
This county sits among the highest-risk counties nationally on FEMA's National Risk Index, a composite score of 88.8/100 (Relatively Moderate). Expected Annual Loss is rated Relatively Moderate (roughly $129.0M in annualized losses). Social vulnerability reads Very Low and community resilience Very High, both critical modifiers of realized harm here. Of the 18 hazards FEMA models, Tornado stands out as the sharpest exposure here, rated Relatively High. FEMA's modeled frequency puts that hazard at roughly once every 3 years here, based on 20 historical events on record.

How often does each hazard strike Hamilton 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 |
|---|---|---|
| Tornado | Relatively High | roughly once every 3 years |
| Hail | Relatively Moderate | an average of 4.4 times per year |
| Winter Weather | Relatively High | an average of 10 times per year |
| Riverine Flooding | Relatively Moderate | an average of 1.8 times per year |
| Cold Wave | Relatively Moderate | an average of 3.4 times per year |
| Heat Wave | Relatively Moderate | 4.3 modeled event-days per year |
| Earthquake | Relatively Low | roughly once every 541 years |
| Lightning | Relatively High | an average of 46 times per year |
| Strong Wind | Relatively Moderate | an average of 4.8 times per year |
| Ice Storm | Relatively Moderate | roughly once every 1 years |
| Drought | Relatively Low | 1.4 modeled event-days per year |
| Landslide | Very Low | roughly once every 11 years |
| Hurricane | Very Low | roughly once every 87 years |

What Severe Storm declarations mean here
Severe Storm is the most frequent declaration type on Hamilton County's record, 42% 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: Tornado
Tornado exposure is the most spatially concentrated in the model: total destruction along a narrow corridor with intact property either side. County-level averages therefore understate severity badly for anyone actually in the path, and overstate it for everyone else.
For Hamilton County the two measures on this page point the same way: Tornado is the county's highest-rated modeled hazard (Relatively High), and Severe Storm declarations also lead its federal record. Where the model and the declaration history agree, the reading is comparatively straightforward, the hazard is both expected and repeatedly realised.
National Risk Index ratings are modeled estimates of expected annual loss, not predictions of what will happen in any given year.

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.
