The Virginia Tech Seismological Observatory (VTSO) operates a digital seismic network with stations throughout Virginia. Along with other southeastern regional seismic networks, VTSO contributes to earthquake monitoring, information dissemination, and seismic hazard assessment objectives in the southeastern United States.

VTSO is supported by contributions from Mr. Daniel Yancey and BP.

VTSO compiles a Southeastern U.S. Earthquake Catalog which can be browsed or downloaded. This catalog contains both historical and recent, instrumentally located, earthquakes in the southeastern U.S. region. Since 1977, the southeastern regional seismic network operators have contributed over 1500 instrumentally located hypocenters and magnitudes to the catalog. Complete phase data and other seismological information for those events are contained in a series of Bulletins compiled by VTSO. The Southeastern U.S. Seismic Networks Bulletins can be also be browsed and downloaded. The instrumentally-located earthquake hypocenters and magnitudes from the SEUSSN bulletins 1-38 (1977-2003) are also contained in the ANSS Composite Earthquake Catalog.
