Seismotectonic maps in the vicinity of the lower Wabash Valley, Illinois, Indiana, and Kentucky - Digital Spatial Database: Locations of stress orientations

Metadata Updated: November 12, 2020

NOTE: Location of one point, near -88.65, 38.95, was incorrect when Sheet A was published. The location is .5 degree south, and is corrected in this dataset. This cover contains locations of places where greatest horizontal compressive stress (S(Hmax)) orientations have been determined either by observation of well-bore breakouts or where focal mechanism solutions have been determined from earthquakes. Well-bore breakouts are observed from 0 to 1.4 km, whereas earthquakes generally occur deeper. The earthquake focal mechanisms show both reverse and strike-slip faulting. Overall the stress indicators show easterly trending S(Hmax).
