USGS geologists document potential paleoliquefaction features from past seismicity at the southernmost edge of the Central Virginia Seismic Zone. Radiocarbon data suggest these features along Fountain Creek near Skippers, VA may be related to an earthquake that occurred near Petersburg, VA in the late 1700s.

Physical Scientist Molly Huber of the Florence Bascom Geoscience Center examines tree roots in a location where a root cookie was recently cut.
Molly was there as part of a stream habitat/riparian assessment at Orson Creek in south central Pennsylvania.

Map showing the location of the study area in Maryland and Virginia. Each dot represents an outcrop (red), core (black) or water well (orange) where Paleogene formation thicknesses were obtained. The circular feature in the southern portion of the map is the Chesapeake Bay Impact Crater. Paleogene sediments are not present in the crater.

Four close-up images of a longer sediment core (bottom). The light coloring indicates coarser sand that likely occurred from overwash flooding during a previous hurricane. This is one of a few cores collected in northwest Florida by the USGS and partners to help understand past hurricane activity in the Gulf of Mexico and northern Atlantic Ocean.
