Description: | Technical Memorandum Introduction: The investigation reported herein was undertaken to determine the relationships, if any, existing between fault systems and crevasses in the Lower Mississippi River Alluvial Valley and the effects of faults on stream diversions and orientations of physiographic features. The area dealt with includes portions of the following states which lie within the Alluvial Valley; southeast Missouri; the southern tip of Illinois; western portions of Kentucky, Tennessee, and Mississippi; eastern Arkansas; and Louisiana. The initial step in this investigation was the assembly of information from borings and data on physiographic evidences of faulting within alluvial deposits of this region in order to develop criteria for the recognition of faulting in such geologically youthful sediments. The extent and influence of faulting were then reviewed in detail for certain specific areas such as Reelfoot Lake, Tennessee, Big Creek, Arkansas, and Catahoula Lake, Louisiana, and the overall pattern of faulting within the Lower-Mississippi Valley was mapped from aerial photograph mosiacs. In addition, all available information was gathered on earthquake activity affecting the Lower Mississippi Valley, with emphasis on data concerning soil disturbances within the flood plain. This information is included as an appendix to this report. Since it is indicated that earthquakes resulting from faulting are of fairly common occurrence in the Lower Mississippi Valley and that former fault traces manifest themselves in several ways through the recent alluvial blanket, criteria for the recognition of faulting in alluvial deposits are reviewed in this report.
