Anderson County's FEMA Risk Index score
Which hazard drives modeled loss here?
FEMA's modeled annual dollar loss for Anderson County is led by Riverine Flooding (about $16.3M 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 Anderson County's hazard record show?
Reading the federal records together
The NFIP claims register shows a middle-volume loss record here: 55 paid claims, totaling $262.0K. PlainHazard uses 50-499 claims for this descriptive band; FEMA does not publish it as a safety or coverage category. The $4.8K 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. Anderson County's 22 federal records stand 3% above the Tennessee county mean of 21.4. 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, 73.2/100, rated Relatively Low. Its Expected Annual Loss rating is Relatively Low (roughly $29.5M 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 1.3 times per year here.

How often does each hazard strike Anderson 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 1.3 times per year |
| Earthquake | Relatively Low | roughly once every 252 years |
| Cold Wave | Relatively Moderate | roughly once every 1 years |
| Tornado | Relatively Moderate | roughly once every 8 years |
| Lightning | Relatively Moderate | an average of 57 times per year |
| Riverine Flooding | Relatively Moderate | an average of 1.1 times per year |
| Winter Weather | Relatively Moderate | an average of 5.1 times per year |
| Strong Wind | Relatively Moderate | an average of 5.2 times per year |
| Ice Storm | Relatively Moderate | roughly once every 2 years |
| Hail | Relatively Low | an average of 3 times per year |
| Wildfire | Very Low | roughly once every 365 years |
| Hurricane | Very Low | roughly once every 58 years |
| Heat Wave | Very Low | 0.8 modeled event-days per year |

What Severe Storm declarations mean here
Severe Storm is the most frequent declaration type on Anderson County's record, 45% 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 Anderson 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 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.
