Airborne Geophysical Surveys over the 2011 Mineral, Virginia, Earthquake Area

Metadata Updated: November 20, 2025

The 2011 moment magnitude (Mw) 5.8 central Virginia earthquake was felt by millions of people and caused significant damage in the eastern United States. As part of efforts to better understand the faults and geologic features associated with the earthquake, the U.S. Geological Survey commissioned airborne geophysical surveys over the epicentral area. The surveys were conducted from July 15, 2012 - July 25, 2012, by Sander Geophysics Limited. The area was flown along a draped surface with a nominal survey height above ground of 125 meters. The flight line spacing was 200 meters for traverse lines and 2000 meters for control lines. Here we present downloadable gravity, magnetic, and radiometric data from those surveys and summarize research results based on those datasets. The data are provided as image (GeoTiff or kmz), grid (gxf) or flight line (csv) data.
