In an interview with NPR, seismologist John Vidale said that the Earth’s crust actually has ancient faults in many places, but that “most of them don’t move very much…the mystery is really what’s pushing the faults to make it move now — and there are a lot of theories.”
Vidale said one of these theories is that the plate is in the process recovering from the end of the last glacial period, relieving itself of pressure incurred while the region was still covered in ice by rising and putting stress on the Earth’s crust.
Chrisopher Bailey, chairman of the geology department at William and Mary, told NPR that another explanation could be that the current movements of the North Atlantic tectonic plate are putting pressure on the same ancient faults mentioned by Vidale.
According to David Spears, Virginia’s state geologist, there are three such faults in Virginia alone.
“An area of central Virginia, along a line that runs from Fredericksburg to Gereensboro, N.C., used to be a plate boundary,” Spears said. “Perhaps there’s some leftover stress in the crust.”
