RICHMOND, Va. - Researchers are preparing to conduct a two-month study of earthquakes in central Virginia.
20 seismic stations are being installed for the study by researchers from Virginia Tech and the U.S. Geological Survey. The installations are expected to be completed by Monday.
Virginia Tech seismologist Martin Chapman said that researchers expect to learn a lot about earthquakes in eastern North America because of the region's history of seismic activity.
More than 450 aftershocks have been recorded since a magnitude 5.8 earthquake near Mineral in August 2011.
Chapman says the seismic stations will be located in Louisa, Powhatan, Goochland, Cumberland, Buckingham, Fluvanna and Albemarle counties.
