Summary

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

Purpose

The data was generated to help in understanding the seismotectonic hazardsin the vicinity of the lower Wabash Valley. This data complements similardata collected in the vicinity of New Madrid, MO, see US Geological SurveyOpen-File Report 95-0574, available at http://pubs.usgs.gov/of/1995/ofr-95-0574
