Risk Overview
About Natural Disaster Risk in Hanover County, Virginia
Hanover's Risk Sits Above the National Average
With a composite risk score of 53.50, Hanover ranks as relatively low but exceeds the national baseline for natural disaster exposure. This means the county faces measurable hazard threats that warrant preparation, though at a more moderate level than high-risk areas across the country.
Above Average Risk for Virginia
Hanover's score of 53.50 significantly outpaces Virginia's state average of 33.27, placing it in the upper tier of risk among Virginia counties. The county's exposure is driven by multiple hazard types rather than a single dominant threat.
Riskier Than Most Nearby Counties
Hanover faces notably higher risk than Harrisonburg (26.59) and Hopewell (17.24) to the south and west, but carries less exposure than Henrico County (83.40) just to the east. Among central Virginia counties, Hanover occupies a middle-to-upper position in the risk spectrum.
Earthquakes and Hurricanes Top Your Threats
Earthquake risk dominates at 83.78—among the highest in the state—while hurricane exposure stands at 74.89, reflecting Hanover's position on the Atlantic seaboard. Flooding also poses significant concern at 61.55, particularly in low-lying areas near the James River and its tributaries.

Hazard Breakdown
Earthquake risk is Hanover County's dominant natural hazard, ranked at the 84th percentile nationally under FEMA's National Risk Index. Hurricane ranks second at the 75th percentile nationally. Additional tracked hazards include flood (62th percentile), tornado (51th percentile), wildfire (32th percentile).
Preparedness Context
At the 84th percentile nationally for earthquake risk, Hanover County is in a zone where a post-earthquake communications plan matters almost as much as pre-earthquake structural preparation — phone networks are typically congested for hours after a significant event. The county's hurricane risk at the 75th percentile nationally is a seasonal consideration alongside the year-round earthquake threat, requiring awareness of both hazard types. For Hanover County households, the three highest-impact earthquake preparedness actions are: (1) anchor heavy furniture and water heaters, (2) store three days of water at one gallon per person per day, and (3) identify a family reunification plan for the post-quake communication blackout period.
Regional Context
A composite score 20.2 points above the Virginia state average puts Hanover County in a higher-risk category than most counties in the state.
