The verdict
The declaration register is comparatively quiet for Kusilvak Census Area. Its 2 federal records sit 72% below the Alaska county mean and above the count for 0% of counties nationally. That historical total does not set the National Risk Index: FEMA's separate loss-and-vulnerability model ranks the county in the riskiest 42%.

FEMA National Risk Index composite score vs. the Alaska county average
What does Kusilvak Census Area's hazard record show?
FEMA National Risk Index
This county carries a high composite score on FEMA's National Risk Index, 57.9/100, rated Relatively Low. Its Expected Annual Loss rating is Very Low (roughly $10.9M in annualized losses), and a Very High social-vulnerability profile combined with Very Low community resilience shapes how much of that raw exposure becomes realized harm. Of the 18 hazards FEMA models, Cold Wave stands out as the sharpest exposure here, rated Relatively High. FEMA's modeled frequency puts that hazard at an average of 3.8 times per year here, based on 65 historical events on record.
Declaration frequency
Kusilvak Census Area's federal file is quiet on both comparisons: 2 declarations, 72% below the Alaska county mean. Of those, 2 use the Major Disaster code. The register covers 3 years and averages 0.7 entries a year. Flood is the most frequent incident label at 1. A small federal count does not include undeclared local events and is not evidence of zero hazard exposure.
Reading the federal records together
No paid-claim row for this county appears in the NFIP county table used by PlainHazard. That absence is not evidence that flooding never occurred: the register observes claims under federal flood-insurance policies, not uninsured losses, emergency reports, or every flood outside the program. The FEMA declaration history below is therefore the available federal-action record on this page.
Start with the state benchmark: a Alaska county averages 7.2 federal declaration records, while Kusilvak Census Area has 2. The gap is 72% below that mean. Fewer entries indicate a quieter history of recorded federal actions, not immunity from a hazard and not a prediction about what happens next.

How often does each hazard strike Kusilvak Census Area?
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. These modeled frequencies are not forecasts.
| Hazard | NRI Risk Rating | Recurrence |
|---|---|---|
| Cold Wave | Relatively High | an average of 3.8 times per year |
| Winter Weather | Relatively Moderate | an average of 28 times per year |
| Landslide | Relatively Low | roughly once every 15 years |
| Wildfire | Very Low | roughly once every 1,080 years |
| Volcanic Activity | Very Low | roughly once every 5,000 years |
| Earthquake | Very Low | roughly once every 368 years |
| Avalanche | Very Low | roughly once every 100 years |
| Ice Storm | Very Low | roughly once every 67 years |
| Lightning | Very Low | an average of 15 times per year |
| Tornado | Very Low | roughly once every 106 years |
| Strong Wind | Very Low | roughly once every 17,520 years |
| Hail | Very Low | roughly once every 27,541 years |

What Flood declarations mean here
Flood is the most frequent declaration type on Kusilvak Census Area's record, 50% 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: Cold Wave
Cold Wave measures exposure to extreme cold rather than to snow. Its harm is concentrated in health effects, burst infrastructure and energy demand spikes, and it falls hardest where the building stock and the grid were not built with sustained cold in mind.
Worth noting for Kusilvak Census Area: the model and the federal record do NOT point at the same hazard. Cold Wave carries the highest modeled rating (Relatively High), 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 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.
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 Kusilvak Census Area
Against a Alaska county mean of 7 declarations, Kusilvak Census Area, AK records 2, or 72% fewer. PlainHazard classifies that historical total as low activity.
- Major Disaster is the largest group (2 of 2) in a declaration history that remains below its state benchmark; frequency here is not a forecast. Alaska overview
- Nationally the county exceeds 0% of recorded county totals, but its own Alaska benchmark is higher. The ranking keeps those two contexts separate. Most-disaster rankings
- With no NFIP county row, the declaration register and modeled NRI remain distinct evidence rather than substitutes for a claims history. Disaster-data guide
A below-average federal record is not a safety guarantee. Use National Weather Service alerts and local emergency-management notices for present conditions, not this historical comparison.
