There are two main seismic zones in Virginia which are more susceptible to earthquakes and identified by the rivers along those faults. The James River follows the Central Virginia Seismic Zone from Charlottesville to Richmond, and the New River follows another zone, from Radford to the West Virginia border.
Based on historical earthquake maps from US Geological Survey, the main areas of seismic activity are west of Richmond (Cumberland, Goochland, Fluvanna, Buckingham counties and to lesser degree the neighboring areas) and in the western part of the state, especially in the Giles country and along the Tennessee border. Looking at USGS National Seismic Hazard Maps, these observations can be confirmed as there is a below-moderate risk area going across the western part of the state, narrowing down and then expanding in a wider circle around Richmond. The rest of the state (northern, eastern, and southeastern parts) has low hazard.
