Risk Overview

About Natural Disaster Risk in Berkshire County, Massachusetts

Berkshire moderately exceeds national risk

Berkshire County's composite risk score of 84.00 sits comfortably above the national average, placing it in the relatively moderate risk tier. While not among the nation's highest-risk counties, Berkshire residents face measurably greater disaster exposure than Americans in lower-risk areas. The score reflects a mix of flood, earthquake, and storm hazards concentrated in the county's terrain and position.

Middle-of-the-pack risk for Massachusetts

Berkshire County ranks fifth among Massachusetts' eight counties with a composite score of 84.00, sitting above the state average of 78.84. Only Essex, Hampden, Bristol, and Barnstable counties face higher composite risk. This mid-tier position reflects Berkshire's inland, western location—protecting it from the most intense coastal hazards.

Safer than coastal counties, riskier inland

Berkshire's 84.00 score runs notably lower than coastal neighbors like Bristol (89.85) and Barnstable (89.09), yet remains materially higher than Franklin County (60.72) and Hampshire County (69.88) to the east. Berkshire's westernmost position in Massachusetts means fewer tropical storm impacts but continued earthquake and flood exposure. Geography here works in your favor compared to the coastline.

Floods and earthquakes lead the list

Berkshire residents face the most serious threat from flooding (90.65) and earthquakes (72.14), with hurricane risk (83.60) representing a secondary but real concern. Wildfire (25.19) and tornado (48.82) risks remain notably lower than in other counties. Rivers, groundwater, and underground geology drive Berkshire's top hazards.

Prioritize flood and earthquake protection

Given flood and earthquake risks both above 70, securing flood insurance and reviewing your homeowners policy for earthquake coverage should be immediate priorities. If you're in a mapped flood zone or near rivers, elevation and waterproofing improvements pay dividends over time. Earthquake safety—from securing heavy furniture to reinforcing foundations—matters more here than in many other regions.

Risk Advisory: Berkshire County

Risk Verdict

Natural hazard risk in Berkshire County is higher than the majority of U.S. counties, with a national composite rank of 84th. Berkshire County's elevated composite score reflects cumulative multi-hazard exposure; households should prepare for the county's two or three primary hazard types.

Hazard Breakdown

Flood risk is Berkshire County's dominant natural hazard, ranked at the 91th percentile nationally under FEMA's National Risk Index. Hurricane ranks second at the 84th percentile nationally. Additional tracked hazards include earthquake (72th percentile), tornado (49th percentile), wildfire (25th percentile).

Preparedness Context

With flood ranked as the primary hazard at the 91th percentile nationally, Berkshire County households should build a go-bag that includes important documents, medications, and supplies to sustain the family for at least three days if evacuation is needed. The county's second-ranked hazard, hurricane at the 84th percentile nationally, means Berkshire County residents face compounding risks from multiple natural hazard types during peak seasons. A waterproof container for documents (insurance policies, ID, prescriptions) and a clear household communication plan for when phone networks are congested are the two highest-value low-cost preparedness steps for Berkshire County households.

Regional Context

A composite score 5.2 points above the Massachusetts state average puts Berkshire County in a higher-risk category than most counties in the state.

What types of natural hazards affect Berkshire County?
Berkshire County is evaluated for five major natural hazard types: flooding (91th percentile), hurricane (84th percentile), earthquake (72th percentile), tornado (49th percentile), wildfire (25th percentile). The highest-risk hazard is flooding at the 91th 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 Berkshire County risk compare to the Massachusetts average?
Berkshire County's composite risk percentile is 84th, compared to the Massachusetts state average of 79th percentile. The state's overall risk rating is Relatively Low. This means Berkshire County faces higher natural disaster risk than the typical county in Massachusetts.
Is Berkshire County at risk for flooding?

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 Berkshire County higher risk than average?
Berkshire County's composite risk score of 84th percentile is above the Massachusetts state average of 79th percentile. This elevated risk is driven by flooding exposure (91th percentile), along with hurricane and earthquake risk. Geographic location, terrain, climate patterns, and proximity to flood zones or fault lines all influence a county's risk profile.
