Title:
Seismotectonic maps in the vicinity of the lower Wabash Valley, Illinois, Indiana, and Kentucky - Digital Spatial Database: Wells with structural control
Abstract:
These wells assist in characterizing structures at hypocentral depths in the Wabash Valley. We show locations of 32 wells that provided information about depths to basement, the rifting history of the Rough Creek Graben and Reelfoot rift, coeval rifting elsewhere in the map area, or the modern stress field in which earthquakes occur.
