# Atlas Commons research objects — natural-hazard risk profile for Nebraska

Nebraska's natural-hazard risk from public federal sources, with each figure's epistemic status labeled: recorded facts (NOAA storm events, property damage, and deaths for the 2025 storm year) are observations of what occurred; the cross-state rank is derived (an in-house ranking over the recorded single-year totals); rating figures (FEMA expected annual loss, FEMA NRI composite score, social vulnerability and community resilience indices) are models that authorities compute — not direct measurements; the two-lens and boundary notes are interpretation — state-level aggregates, not a verdict on any specific property.

## Claims

### FEMA EXPECTED annual loss from natural hazards in Nebraska is $1,336,726,319 (a modeled expectation)

**MODELED.** The FEMA National Risk Index models an EXPECTED annual loss of $1,336,726,319 from all natural hazards for Nebraska (93 counties, 2026). An annualized expectation of future loss, not a record.

Source: FEMA National Risk Index — https://hazards.fema.gov/nri/
Falsifier: occurred=FALSE: a MODELED figure — an authority's computed quantity ESTIMATING an independent/latent value (an index or annualized expectation), REPRODUCIBLE from its disclosed inputs, NOT a record of an event. adjudged=TRUE because FEMA National Risk Index (an external authority) computes and publishes it. The grounding promises "reproduce this from the inputs" — so a categorical authority VERDICT that is NOT reproducible (a star rating, a risk class) is a 'determination', not 'modeled'. Superseded by the next release.

### FEMA NRI composite risk SCORE for Nebraska is 25.7976/100 (dominant hazard: Hail)

**MODELED.** The FEMA National Risk Index composite risk score (0-100, county average; ~50 is the national midpoint, so above 50 is above the typical U.S. county) for Nebraska is 25.7976. A modeled composite index, not a recorded quantity.

Falsifier: occurred=FALSE: a MODELED figure — an authority's computed quantity ESTIMATING an independent/latent value (an index or annualized expectation), REPRODUCIBLE from its disclosed inputs, NOT a record of an event. adjudged=TRUE because FEMA National Risk Index (an external authority) computes and publishes it. The grounding promises "reproduce this from the inputs" — so a categorical authority VERDICT that is NOT reproducible (a star rating, a risk class) is a 'determination', not 'modeled'. Superseded by the next release.

### FEMA NRI social vulnerability SCORE for Nebraska is 26.9279/100 (a modeled index of who bears the risk)

**MODELED.** The FEMA National Risk Index social vulnerability score (0–100, county average; built on the CDC/ATSDR Social Vulnerability Index) for Nebraska is 26.9279. A modeled composite of the social conditions that worsen a community's hazard outcomes — not a record of harm, and not a judgment of any person.

Falsifier: occurred=FALSE: a MODELED figure — an authority's computed quantity ESTIMATING an independent/latent value (an index or annualized expectation), REPRODUCIBLE from its disclosed inputs, NOT a record of an event. adjudged=TRUE because FEMA National Risk Index (CDC/ATSDR Social Vulnerability Index) (an external authority) computes and publishes it. The grounding promises "reproduce this from the inputs" — so a categorical authority VERDICT that is NOT reproducible (a star rating, a risk class) is a 'determination', not 'modeled'. Superseded by the next release.

### FEMA NRI community resilience SCORE for Nebraska is 45.5204/100 (a modeled index of the capacity to absorb and recover)

**MODELED.** The FEMA National Risk Index community resilience score (0–100, county average; built on the HVRI Baseline Resilience Indicators for Communities) for Nebraska is 45.5204. A modeled composite of a community's capacity to prepare for, absorb, and recover from hazards — not a measured outcome.

Falsifier: occurred=FALSE: a MODELED figure — an authority's computed quantity ESTIMATING an independent/latent value (an index or annualized expectation), REPRODUCIBLE from its disclosed inputs, NOT a record of an event. adjudged=TRUE because FEMA National Risk Index (HVRI Baseline Resilience Indicators for Communities) (an external authority) computes and publishes it. The grounding promises "reproduce this from the inputs" — so a categorical authority VERDICT that is NOT reproducible (a star rating, a risk class) is a 'determination', not 'modeled'. Superseded by the next release.

### NOAA recorded 1,428 storm events in Nebraska in 2025: $53,069,810 property damage, 3 direct deaths

**RECORDED.** The NOAA Storm Events Database records 1,428 storm events that occurred in Nebraska in 2025, with $53,069,810 in reported property damage, 3 direct deaths, and 8 direct injuries, across 20 distinct peril types. These are RECORDED occurrences (occurred=true) — the historical event log, NOT the modeled FEMA risk score above. Damage figures are NOAA's reported estimates and can undercount.

Source: NOAA NCEI Storm Events Database — https://www.ncei.noaa.gov/stormevents/
Falsifier: A RECORD of measured/reported events (occurred=true) from NOAA NCEI Storm Events Database; superseded when NOAA NCEI Storm Events Database publishes its next release.

### Thunderstorm Wind was the most consequential recorded peril in Nebraska in 2025 (1 deaths, $43,101,810)

**RECORDED.** Of all peril types NOAA recorded in Nebraska in 2025, Thunderstorm Wind caused the most direct deaths (1) across 276 events, with $43,101,810 in reported property damage. A recorded ranking within the actual event log (occurred=true), not a forecast of future perils.

Source: NOAA NCEI Storm Events Database — https://www.ncei.noaa.gov/stormevents/
Falsifier: A RECORD of measured/reported events (occurred=true) from NOAA NCEI Storm Events Database; superseded when NOAA NCEI Storm Events Database publishes its next release.

### Nebraska's 2025 storm deaths are 1.53 per million residents — 16th of 51 states population-normalized (raw count: 26th of 51)

**DERIVED.** Normalized for population, Nebraska's 3 direct storm deaths in 2025 are 1.53 per million residents — the 16th-highest of 51 states, against a typical state's 0.91. The raw count ranks 26th of 51, but per-capita de-confounds state size and is the truer cross-state comparison. In-house rankings over NOAA's recorded single-year counts (occurred=false as a ranking, adjudged=false); population is the Census resident total summed from counties.

Source: Property Atlas — population-normalized rank within the recorded single-year state death distribution — https://www.ncei.noaa.gov/stormevents/
Falsifier: occurred=FALSE (a calculation, not an event) and adjudged=FALSE (a transparent in-house formula, not an authority's verdict — no external adjudicator). Reproduce it from its named inputs; falsified if the formula or inputs are wrong. Lower warrant than the adjudged figures above.

### Model and record diverge in Nebraska: FEMA's dollar-weighted dominant hazard is Hail; the 2025 deadliest force was Thunderstorm Wind

**INTERPRETATION.** FEMA's National Risk Index, weighting expected-loss DOLLARS, names Hail Nebraska's dominant hazard. The 2025 NOAA record, weighting LIVES, shows Thunderstorm Wind as the deadliest force. Both are correct for the question they answer — dollars and lives are different lenses on the same place. This is the atlas's reading (occurred=false, adjudged=false), not a claim that either authority is wrong.

Source: Property Atlas framing (over the FEMA model and the NOAA record above) — https://property-atlas.ryanjhunter.workers.dev/
Falsifier: occurred=FALSE (a framing, not an event) and adjudged=FALSE (the atlas's reading, not a FEMA or NOAA verdict). The FEMA dominant hazard (modeled) and the deadliest recorded peril (recorded) above are each grounded; this two-lens contrast is the interpretation that joins them.

### What this risk profile is — and is NOT — for Nebraska (the epistemic boundary)

**INTERPRETATION.** Every figure above is an official state-level figure from a named public authority (measured or rating, as labeled). They do NOT advise on a specific property's insurability, value, or whether to buy or insure it. For a property-level answer, use the FEMA Map Service Center and a licensed insurance producer.

Source: Property Atlas framing (over the FEMA/NOAA figures above) — https://property-atlas.ryanjhunter.workers.dev/
Falsifier: occurred=FALSE (a framing, not an event) and adjudged=FALSE (the atlas's boundary, not an authority's verdict) — the LOWEST-warrant claim here. The measured figures (NOAA storm loss) and the rating figures (FEMA expected loss, NRI score) above are each grounded; this is the only context note, and the four-status says so.
