Notes: For the U.S. Nuclear Regulatory Commission. Report. No. NUREG/CR-2908.

This is the final report of the multi-year program of geologic and geophysical investigations of faulting in southwestern Indiana. During the first 2 years of the investigation in Indiana, mapping and characterization of the Wabash Valley Fault System were accomplished using data mostly from numerous geophysical logs of closely drilled wells in Posey and Gibson counties. Both surface and subsurface investigations were conducted in a second area of known faulting in Perry and Spencer counties. Finally, test drilling and concentrated field mapping of the Mt. Carmel Fault in south-central Indiana completed the study. The report includes interpretation of the relationship of the faulting in southwestern Indiana to regional structure and tectonics, especially with regard to association with the New Madrid Fault Zone and its potential extension to the northeast.
