An electron-microscope image of a microbe (Bacillus infernus) found 2,700 meters (8,860 feet) underground in Virginia. From Boone et al., 1995 (https://doi.org/10.1099/00207713-45-3-441).

Under natural conditions, water levels in wells completed in many confined aquifers rise above the land surface, resulting in artesian flow. The well shown in the photograph was drilled near Franklin, Virginia, in 1941 to a depth of about 600 feet in confined aquifers. The initial water level in the well was about 7 feet above land surface.

Damage to a house in Louisa County, Virginia, after a magnitude 5.8 earthquake on August 23, 2011.

USGS geophysicist Anjana Shah stands next to a Cessna Grand Caravan airplane that took measurements over Virginia's Louisa, Goochland and Fluvanna counties. The data collected will help USGS scientists locate buried geologic features associated with the August 23, 2011 earthquake and its aftershocks. Surveys were conducted from 7/15- 7/25.
