What does Ailuk's hazard record show?
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.
The declaration register points in the busier direction. Ailuk's 2 federal records stand 0% above the Marshall Islands county mean of 2.0. 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.

What Typhoon declarations mean here
Typhoon is the most frequent declaration type on Ailuk's federal record, 50% of its declarations. Atlantic tropical systems run on a defined season, 1 June to 30 November, with most activity concentrated between August and October; Pacific and territorial basins run on their own calendars. A single named storm routinely produces one declaration number covering a long corridor of counties at once, well inland as well as on the coast, which is why an affected county's count can jump by several in one year without several separate events having occurred.
One practical distinction matters when reading these records: a tropical declaration usually bundles wind, storm surge and inland rainfall flooding under a single incident, but the insurance behind them is split. Wind damage falls to property insurers, while flood and surge damage is covered only under a separate National Flood Insurance Program policy. That is why a county can show heavy declaration activity and a comparatively small NFIP claims record, or the reverse.
Declaration counts describe past federal action. They are a record of what was declared, not a forecast of future hazard probability.

How these peers are chosen
Cohort: FEMA declaration county equivalents in the freely associated states. 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.
