Risk Overview

About Natural Disaster Risk in Montgomery County, Virginia

Montgomery faces above-average national risk

With a composite risk score of 47.52, Montgomery County rates as Relatively Low nationally but sits above most U.S. counties in overall natural disaster exposure. Your community experiences moderate risk compared to American averages.

Higher than typical Virginia county

Montgomery's 47.52 score exceeds Virginia's average of 33.27 by 42 percent, placing it among the state's higher-risk counties. You face notably more natural disaster exposure than typical Virginia communities.

Regional risk stands notably elevated

At 47.52, Montgomery significantly outpaces nearby Nelson County (34.10) and Northumberland County (39.98), but remains lower than Northampton County (44.47) and well below Newport News (72.23). Your position reflects the Blue Ridge region's seismic and topographic exposure.

Earthquake and flood pose greatest threats

Earthquake risk reaches 73.41—Virginia's highest and among the nation's most notable inland seismic zones—while flood risk stands at 63.61. Tornado (23.70), hurricane (57.11), and wildfire (36.96) threats remain secondary but still merit attention.

Earthquake insurance is non-negotiable

Standard homeowners policies exclude earthquake damage, but Montgomery's 73.41 seismic score makes separate coverage critical for your county. Bundle flood insurance, secure heavy furniture and appliances, and check that your home's foundation meets modern seismic building standards.

Risk Advisory: Montgomery County

Risk Verdict

Montgomery County has a below-average natural disaster risk profile, scoring at the 48th percentile nationally under FEMA's National Risk Index. Montgomery County residents can take confidence from a 48th percentile ranking, but even lower-risk counties benefit from a practiced household communication plan and awareness of the specific hazards listed above.

Hazard Breakdown

Earthquake risk is Montgomery County's dominant natural hazard, ranked at the 73th percentile nationally under FEMA's National Risk Index. Flood ranks second at the 64th percentile nationally. Additional tracked hazards include hurricane (57th percentile), wildfire (37th percentile), tornado (24th percentile).

Preparedness Context

Earthquake risk is Montgomery County's leading natural hazard, ranked at the 73th percentile nationally. Securing tall furniture, water heaters, and bookcases to walls with anti-tip hardware is among the simplest and most effective life-safety measures households can take. The county's flood risk at the 64th percentile nationally is a seasonal consideration alongside the year-round earthquake threat, requiring awareness of both hazard types. Montgomery County residents should locate the main gas shutoff valve and keep an appropriate wrench nearby — gas leaks cause a significant share of earthquake-related injuries and fires, and the shutoff step is safe to take immediately after shaking stops.

Regional Context

Montgomery County's composite risk score sits 14.2 points above the Virginia county average, placing it among the more hazard-exposed counties in the state.

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 Montgomery County higher risk than average?
Montgomery County's composite risk score of 48th percentile is above the Virginia state average of 33th percentile. This elevated risk is driven by earthquake exposure (73th percentile), along with flooding and hurricane risk. Geographic location, terrain, climate patterns, and proximity to flood zones or fault lines all influence a county's risk profile.
