Map of Earthquake Epicenters of West Virginia: 1824 through 2013

Updated 10/23/2013! Earthquake epicenter data were compiled from several regional "catalogs". These catalogs consist of seismic event information that have been reviewed by seismologists. Unless otherwise noted, earthquake catalogs do not contain readings from "blast" or other related mining activity. Earthquake records are divided into two types: "historic" ones which were felt or recorded without sophisticated seismic equipment and "instrumental" ones that have data derived from networks of sophisticated equipment. Download this map: ♦ An interactive, geo-enabled, layered with data (3.44 MB) here: PDF . (What's a geo-enabled, layered PDF?) ♦ Download a detailed Microsoft Excel workbook that was used to create the map of the earthquake epicenters here: XLSX.

Seismic Stations in West Virginia

WVGES has an official USGS seismic station with two seismometers on site. Like radio stations with call letters, ours is "MCWV" which is "Mont Chateau West Virginia". Information about the MCWV Station can be found here. In addition, since the summer of 2013, fourteen new seismic stations have been installed around West Virginia as part of the Transportable Array Program sponsored by IRIS (Incorporated Research Institutions for Seismology). These new seismic stations will be in the state for a two year period. At the end of that time, two to four of the stations will be left in place as the Transportable Array is relocated to the east.
