What does Las Marías Municipio's hazard record show?
Declaration frequency
Nationally, Las Marías Municipio's 25 FEMA records form a high-volume history; within Puerto Rico, however, the count is 8% below the county mean. 15 entries carry the Major Disaster classification. The largest incident group is Hurricane, appearing 12 times. The full 50-year record averages 0.5 declarations annually. A DR label alone does not say whether Individual Assistance, Public Assistance, or both followed.
FEMA National Risk Index
Even the county's top-rated hazard, Earthquake, 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 34 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.
Start with the state benchmark: a Puerto Rico county averages 27.1 federal declaration records, while Las Marías Municipio has 25. The gap is 8% 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 Las Marías Municipio?
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; FEMA expresses drought and heat-wave frequency as event-days per year. These modeled frequencies are not forecasts.
| Hazard | NRI Risk Rating | Recurrence |
|---|---|---|
| Earthquake | roughly once every 34 years | |
| Hail | roughly once every 38 years | |
| Hurricane | roughly once every 5 years | |
| Heat Wave | 0 modeled event-days per year | |
| Riverine Flooding | roughly once every 100 years | |
| Landslide | an average of 69 times per year | |
| Lightning | an average of 63 times per year | |
| Strong Wind | roughly once every 1,673 years | |
| Tornado | roughly once every 654 years |

What Hurricane declarations mean here
Hurricane is the most frequent declaration type on Las Marías Municipio's federal record, 48% 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: Earthquake
Earthquake is the model's clearest example of a hazard with no season and no warning. Its expected loss is driven less by how often shaking occurs than by how much of the building stock predates modern seismic codes, so exposure can be high in places where nothing has happened for a long time.
Worth noting for Las Marías Municipio: the model and the federal record do NOT point at the same hazard. Earthquake carries the highest modeled rating, while the county's declaration history is led by Hurricane. 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 Las Marías Municipio
Against a Puerto Rico county mean of 27 declarations, Las Marías Municipio, PR records 25, or 8% fewer. PlainHazard classifies that historical total as high activity.
- Major Disaster is the largest group (15 of 25) in a declaration history that remains below its state benchmark; frequency here is not a forecast. Puerto Rico overview
- Nationally the county exceeds 71% of recorded county totals, but its own Puerto Rico 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
