Generalized geologic map of the central Virginia Piedmont with faults and earthquakes (M>2, 1973–2011). The earthquake's epicenter and most of the aftershocks lie between the surface traces of two structures, the Spotsylvania Fault, a southeast dipping zone of high ductile strain, and the Chopawamsic Fault, a thrust fault.

CENTRAL VIRGINIA — The solar eclipse wasn't the only excitement in Virginia yesterday. According to the U.S. Geological Survey [U.S.G.S.], a 2.1 magnitude earthquake with a depth of 5.0 km ...
Each of these maps covers an area bounded by two lines of latitude and two lines of longitude spaced 7.5 minutes apart. Nearly 57,000 individual maps in this series cover the 48 contiguous states, Hawaii, U.S. territories, and areas of Alaska near Anchorage, Fairbanks, and Prudhoe Bay. The area covered by each map varies with the latitude of ...
More than 70 people reported feeling the earthquake. A 2.6-magnitude earthquake struck near the North Carolina-Virginia border around 5 a.m. on Tuesday, Oct. 25, the U.S. Geological Survey reports.
Virginia has a low risk of earthquakes, [17] especially in the northern part of the state. The Virginia seismic zone has not had a history of regular earthquake activity. Earthquakes are rarely above 4.5 in magnitude because Virginia is located centrally on the North American Plate, far from plate boundaries. Locations near tectonic plates ...
Moderately damaging earthquakes strike between New York and Wilmington, Delaware, about twice a century, the USGS said, and smaller earthquakes are felt in the region roughly every two to three years.
