Photographing Rock Fall Triggered by 2011 Virginia Earthquake

USGS geologist Ed Harp photographing a small rock fall from a road cut along the Blue Ridge Parkway north of Roanoke, Virginia. This is part of a study documenting landslides triggered from the 2011 magnitude 5.8 earthquake in Virginia. Green grass beneath the rock fragments indicates that the rock fall is fresh and probably was triggered by the earthquake.
