Risk Overview

About Natural Disaster Risk in Park County, Montana

Park County faces elevated national risk

With a composite risk score of 66.28, Park County ranks as Relatively Low compared to the nation, but sits nearly double Montana's average risk level. The county faces more diverse and significant natural hazards than most U.S. communities.

Higher risk than most Montana counties

Park County's score of 66.28 significantly exceeds Montana's state average of 33.31, placing it among the higher-risk counties in the state. The county's elevated exposure stems from multiple overlapping hazard types rather than a single dominant threat.

Most exposed county in its region

Park County's risk score of 66.28 substantially exceeds neighboring Musselshell (17.05) and Powell (9.96) counties. Its earthquake risk (76.40) and wildfire risk (93.51) are among the highest in south-central Montana.

Earthquakes and wildfires dominate threats

Park County faces significant earthquake risk (76.40) and wildfire risk (93.51), with flood hazard (55.63) creating a triple threat. The county's mountainous terrain and proximity to seismic zones amplify exposure to multiple concurrent disasters.

Comprehensive coverage essential here

Residents should secure flood, earthquake, and wildfire coverage through standard homeowners policies or separate riders—comprehensive insurance is critical. Consider retrofitting for seismic safety and creating 100-foot defensible zones around structures to reduce compound risk exposure.

Risk Advisory: Park County

Risk Verdict

Park County ranks at the 66th percentile nationally for natural disaster risk — below the median for U.S. counties. Residents are encouraged to understand which hazards dominate locally and tailor their preparedness accordingly.

Hazard Breakdown

Wildfire risk is Park County's dominant natural hazard, ranked at the 94th percentile nationally under FEMA's National Risk Index. Earthquake ranks second at the 76th percentile nationally. Additional tracked hazards include flood (56th percentile), tornado (8th percentile).

Preparedness Context

Park County's dominant hazard is wildfire, ranked at the 94th percentile nationally. Maintaining at least 30 feet of lean, clean vegetation around structures in Park County and keeping gutters clear of debris significantly reduces ignition risk from wind-driven embers. The county's earthquake exposure at the 76th percentile nationally complements the wildfire risk — saturating rain after burn scarring often triggers secondary flood and debris flow events. Park County's households benefit from reviewing homeowners insurance before fire season, specifically whether the policy covers replacement cost rather than actual cash value, and whether it includes additional living expenses if displacement is required.

Regional Context

Compared to other Montana counties, Park County runs 33.0 composite risk points higher than the state mean — reflecting above-average hazard concentration in this area.

Frequently Asked Questions

What is the natural disaster risk in Park County, MT?
Park County has a FEMA National Risk Index rating of Relatively Low, placing it in the 66th percentile nationally out of 3,144 counties. This composite score reflects the county's overall exposure to natural hazards including floods, wildfires, tornadoes, earthquakes, and hurricanes, weighted by expected annual loss and social vulnerability.
What types of natural hazards affect Park County?
Park County is evaluated for five major natural hazard types: wildfire (94th percentile), earthquake (76th percentile), flooding (56th percentile), tornado (8th percentile). The highest-risk hazard is wildfire at the 94th percentile nationally. These scores are derived from FEMA's National Risk Index, which analyzes expected annual loss, social vulnerability, and community resilience for each hazard type.
How does Park County risk compare to the Montana average?
Park County's composite risk percentile is 66th, compared to the Montana state average of 33th percentile. The state's overall risk rating is Very Low. This means Park County faces higher natural disaster risk than the typical county in Montana.
Is Park County at risk for wildfire?
Yes, Park County's wildfire risk is at the 94th percentile nationally. This places it in the top quartile for this hazard type. For flooding specifically, Park County is at the 56th percentile.
How is natural disaster risk measured?
FEMA's National Risk Index (NRI) calculates risk scores for 18 natural hazard types across all U.S. counties and census tracts. The composite score combines Expected Annual Loss (estimated dollar losses from each hazard), Social Vulnerability (demographic factors affecting disaster impact), and Community Resilience (ability to recover). Percentile scores rank each county against all 3,144 U.S. counties, and risk ratings range from Very Low to Very High.
Why is Park County higher risk than average?
Park County's composite risk score of 66th percentile is above the Montana state average of 33th percentile. This elevated risk is driven by wildfire exposure (94th percentile), along with earthquake and flooding risk. Geographic location, terrain, climate patterns, and proximity to flood zones or fault lines all influence a county's risk profile.
