What does Hawaii County's hazard record show?

Reading the federal records together

FEMA's NFIP table contains a substantial paid-claim history for this county: 800 claims and $23.0M in payments. PlainHazard labels 500 or more claims a heavy registry record; that is a reporting bucket, not an official FEMA risk grade. The average paid claim was $28.7K. NFIP totals exclude uninsured flood losses and do not measure how many properties currently carry a policy.

The declaration register points in the busier direction. Hawaii County's 31 federal records stand 50% above the Hawaii county mean of 20.6. 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 98.5/100 (Relatively High). Expected Annual Loss is rated Relatively High (roughly $365.0M in annualized losses). Social vulnerability reads Relatively Moderate and community resilience Relatively Moderate, both critical modifiers of realized harm here. Of the 18 hazards FEMA models, Volcanic Activity stands out as the sharpest exposure here, rated Very High. FEMA's modeled frequency puts that hazard at roughly once every 45 years here, based on 5 historical events on record.

Declaration frequency

The FEMA register is busy by both local and national comparisons. It contains 31 entries for Hawaii County, including 16 Major Disaster records, 50% above the Hawaii county mean. Across the 53-year span, that works out to 0.6 declarations a year. Fire leads the file with 12 entries. Declaration type records the federal action taken, not every assistance program approved.

Volcanic Activity Very High roughly once every 45 years
Earthquake Relatively High roughly once every 2 years
Riverine Flooding Relatively High an average of 5.6 times per year
Wildfire Relatively High roughly once every 125 years

What Fire declarations mean here

Fire is the most frequent declaration type on Hawaii County's record, 39% of its declarations. Wildfire is the one hazard here with its own dedicated federal instrument: the Fire Management Assistance Grant, which appears in this data as an FM record. An FMAG can be authorised while a fire is still burning, on a timescale of hours, because its purpose is to reimburse the cost of fighting a fire that threatens to become a major disaster.

That distinction matters when comparing counties. An FM declaration is not a presidential major disaster declaration and does not carry the same assistance programmes, so a fire-heavy county's total is not directly comparable with a hurricane-heavy county's total unless the declaration types are separated, which is why they are listed separately on this page.

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: Volcanic Activity

Volcanic Activity is the rarest hazard in the model and the most locally determined. Its modeled exposure follows proximity to specific known systems rather than any regional pattern.

Worth noting for Hawaii County: the model and the federal record do NOT point at the same hazard. Volcanic Activity carries the highest modeled rating (Very High), while the county's declaration history is led by Fire. 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.

Hawaii County's closest FEMA peer: Orangeburg County, SC

Comparisons use published FEMA declaration fields plus the National Risk Index composite for Hawaii County. Record similarity, not a safety rating.

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.
