The 2011 Moment Magnitude 5.8 Mineral, Virginia earthquake was felt by tens of millions of people and caused significant damage in the eastern United States. As part of efforts to better understand the faults, mechanisms and geology associated with the earthquake, the U.S. Geological Survey commissioned airborne geophysical surveys over the epicentral area. Here we summarize research results based on those datasets.
Additional background information can be found in this article by Horton and Williams (2012) published in EOS.
Research results have been published in the Geological Society of America Special Paper The 2011 Mineral, Virginia, Earthquake, and Its Significance for Seismic Hazards in Eastern North America. In particular, Shah and others (2015) use gravity and magnetic data to consider buried structures, and Horton and others (2015) use radiometric data to better understand aftershock recurrence.
