Well below Virginia's average risk

Dinwiddie's score of 19.34 sits significantly below Virginia's state average of 33.27, making it one of the commonwealth's safer communities. This advantage extends across flood, wildfire, and tornado categories, where Dinwiddie consistently underperforms the state mean.

Dinwiddie's earthquake risk of 55.41 is the county's highest hazard exposure, though it remains moderate compared to other Virginia counties. Flood risk (22.11), tornado risk (28.05), and wildfire risk (21.88) all present minimal threats, while hurricane risk stands at 66.54.

Focus on earthquake preparedness

While Dinwiddie's overall risk is low, residents should secure heavy furniture and appliances to walls to reduce earthquake damage. Maintain standard homeowner's insurance and ensure your family has an emergency plan for sheltering in place during seismic events.

Earthquake at the 55th percentile nationally is Dinwiddie County's secondary hazard, often intensified by the same weather systems that produce hurricane conditions. For extended post-storm outages common in Dinwiddie County's hurricane zone, a portable generator (operated outdoors only) and a supply of non-perishable food for at least seven days provides meaningful household resilience.
