Which hazard drives modeled loss here?
FEMA's modeled annual dollar loss for Rota Municipality is led by Tsunami (about $1.5M Expected Annual Loss, Historical Loss Ratio Relatively High), while Coastal Flooding carries the highest National Risk Index rating (null). EAL and risk score use different inputs; they need not agree.

What does Rota Municipality's hazard record show?
FEMA National Risk Index
Even the county's top-rated hazard, Coastal Flooding, only reaches on FEMA's scale, none of the 18 modeled hazards stand out here. FEMA's modeled frequency puts that hazard at roughly once every 83 years here.
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. Rota Municipality's 25 federal records stand 37% above the Northern Mariana Islands county mean of 18.2. 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.

How often does each hazard strike Rota Municipality?
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 |
|---|---|---|
| Coastal Flooding | roughly once every 83 years | |
| Earthquake | roughly once every 13 years | |
| Hurricane | roughly once every 7 years | |
| Riverine Flooding | roughly once every 100 years | |
| Tsunami | roughly once every 8 years | |
| Volcanic Activity | roughly once every 99 years |

What Typhoon declarations mean here
Typhoon is the most frequent declaration type on Rota Municipality's federal record, 68% 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.

The model's sharpest exposure here: Coastal Flooding
Coastal Flooding is modeled separately from riverine flooding because its driver is different: surge, tide and wave action rather than a watershed draining. It is also the hazard whose baseline is moving, since the same storm rides on a higher starting sea level than it used to.
For Rota Municipality the two measures on this page point the same way: Coastal Flooding is the county's highest-rated modeled hazard, and Typhoon declarations also lead its federal record. Where the model and the declaration history agree, the reading is comparatively straightforward, the hazard is both expected and repeatedly realised.
National Risk Index ratings are modeled estimates of expected annual loss, not predictions of what will happen in any given year.

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.

The most active year for disaster declarations in Rota Municipality was 2020, with 4 declarations. The county has FEMA disaster data spanning 1988 to 2026.
What is the FEMA National Risk Index score for Rota Municipality?
According to the FEMA National Risk Index, Rota Municipality, Northern Mariana Islands has an overall risk score of N/A out of 100 (null). The county's social vulnerability rating is Data Unavailable and community resilience is Data Unavailable. The Expected Annual Loss (EAL) score is Very Low, representing $2.8M in annualized losses.
Which natural hazard poses the greatest risk to Rota Municipality?
The top hazard flagged by FEMA's NRI for Rota Municipality as of the latest release is Coastal Flooding (risk rating: null). Other significant hazards include Earthquake (null) and Hurricane (null). FEMA's modeled event frequency puts coastal flooding here at roughly once every 83 years. FEMA derives these ratings from historical event frequency, the assets exposed, and the community's vulnerability profile.
