The verdict
Two federal records point in the busier direction for Oregon County. Its 25 FEMA declarations are 1% above the Missouri county mean and exceed the count for 71% of the 3,266 counties in this registry. Separately, FEMA's National Risk Index places it safer than 49%, based on modeled expected annual loss, social vulnerability, and community resilience.

Oregon County's FEMA Risk Index score
FEMA National Risk Index composite score vs. the Missouri county average
Which hazard drives modeled loss here?
FEMA's modeled annual dollar loss for Oregon County is led by Riverine Flooding (about $4.2M Expected Annual Loss, Historical Loss Ratio Very High), while Earthquake carries the highest National Risk Index rating (Relatively Low). EAL and risk score use different inputs; they need not agree.

What does Oregon County's hazard record show?
FEMA National Risk Index
FEMA's data shows an elevated National Risk Index composite of 48.7/100 for this county (Relatively Low rating). Expected Annual Loss comes in at Very Low (roughly $10.9M in annualized losses). Social vulnerability (Relatively High) and community resilience (Very Low) both factor into how that raw exposure plays out on the ground. Even the county's top-rated hazard, Earthquake, only reaches Relatively Low on FEMA's scale, none of the 18 modeled hazards stand out here. FEMA's modeled frequency puts that hazard at roughly once every 151 years here.
Declaration frequency
The FEMA register is busy by both local and national comparisons. It contains 25 entries for Oregon County, including 17 Major Disaster records, 1% above the Missouri county mean. Across the 52-year span, that works out to 0.5 declarations a year. Severe Storm leads the file with 17 entries. Declaration type records the federal action taken, not every assistance program approved.
Reading the federal records together
This county has a small entry in FEMA's NFIP paid-claims table: 39 claims and $489.6K paid in total. PlainHazard calls 1-49 claims a light registry record, a label for this dataset rather than a finding that flood exposure is low. A short claims history can also reflect insurance take-up, the period covered, or losses that were never insured.
The declaration register points in the busier direction. Oregon County's 25 federal records stand 1% above the Missouri county mean of 24.6. 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.

How often does each hazard strike Oregon County?
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 | Relatively Low | roughly once every 151 years |
| Cold Wave | Relatively Moderate | an average of 1.9 times per year |
| Ice Storm | Relatively Moderate | an average of 1.2 times per year |
| Heat Wave | Relatively Low | 12 modeled event-days per year |
| Landslide | Relatively Low | an average of 1.8 times per year |
| Tornado | Relatively Low | roughly once every 2 years |
| Wildfire | Very Low | roughly once every 487 years |
| Winter Weather | Relatively Low | an average of 9.6 times per year |
| Riverine Flooding | Relatively Low | an average of 1.8 times per year |
| Hurricane | Very Low | roughly once every 46 years |
| Strong Wind | Relatively Low | an average of 2.4 times per year |

What Severe Storm declarations mean here
Severe Storm is the most frequent declaration type on Oregon County's record, 68% of its declarations. In FEMA's vocabulary this covers convective weather: thunderstorm straight-line winds, large hail, and the multi-day outbreaks that often carry embedded tornadoes. Activity is heaviest in spring and summer, though the season varies by region.
These events behave differently from a hurricane on paper. Damage tends to be distributed along a storm track rather than concentrated on a coastline, and a declaration typically follows an outbreak that crossed several counties over a few days, not a single point of impact. Because the qualifying threshold is the cost of uninsured public and individual losses rather than storm intensity, two similar storms can produce a declaration in one year and none in another.
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 Oregon County: the model and the federal record do NOT point at the same hazard. Earthquake carries the highest modeled rating (Relatively Low), while the county's declaration history is led by Severe Storm. 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.
Flood insurance data comes from the FEMA National Flood Insurance Program (NFIP) OpenFEMA claims dataset.
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 Oregon County
Oregon County, MO has 25 federal declaration records, 1% more than the Missouri county mean of 25; its history sits in PlainHazard's high activity band.
- Within this above-state-average declaration file, major disaster leads with 17 of 25 records; the category describes past federal action, not the next likely hazard. Missouri overview
- The state benchmark and national rank point the same way: this count tops the Missouri mean and the totals for 71% of 3,266 U.S. counties. Most-disaster rankings
- A short NFIP claims file cannot establish low flood exposure; the data guide explains the limits of each federal measure. Disaster-data guide
An above-average declaration count records past federal responses; it does not predict the next event. Current warnings come from the National Weather Service and local emergency officials.
