Due to a quirk of local geology, a well in Christiansburg, Virginia is sensitive to seismic waves generated by large earthquakes that occur around the world. This well can be thought of as a natural seismograph: when seismic waves travel past, the water levels in this well rise and fall rapidly. This well gives us a peek into the ways the Earth beneath our feet is constantly changing.

In 2005 and 2006, the International Continental Scientific Drilling Program and the U.S. Geological Survey drilled a 1,766-m-deep test hole near the center of the Chesapeake Bay impact structure. Below you can find publications relevant to the discovery and characterization of the Chesapeake Bay Impact Crater.
