Description:
Abstract:
This cover contains the catalog of earthquake locations, within the project boundary, recorded by the Saint Louis University and Memphis State University seismic networks from July 1974 through December 1995.
Purpose:
The data were generated to help in understanding the seismotectonic hazards in the vicinity of the lower Wabash Valley. These data complement similar data collected in the vicinity of New Madrid, MO US Geological Survey Open-File Report 95-0574, available at http://pubs.usgs.gov/of/1995/0574/
