REMOTE SENSING OF ALLUVIAL TERRAIN IN A HUMID, TECTONICALLY ACTIVE SETTING: THE NEW MADRID SEISMIC ZONE

The first large-scale feature discovered in the New Madrid seismic zone that may be the surface expression of a seismogenic fault of the great New Madrid earthquakes of 1811-1812 is revealed by Landsat MSS imagery, SPOT XS digital data, and aerial photography. This feature, that the authors have named the Boot-heel lineament, trends at least 80 km in a north-northeast direction through northeastern Arkansas and southeastern Missouri. Other relatively short, northeast- and northwest-trending lineaments were located in Holocene alluvium in north-western Tennessee. Some of these lineaments may correlate with previously published reports of subsurface faults. A west-facing scarp identified on the SPOT image in the southern part of Reelfoot Lake may represent a normal fault scarp that forms a graben structure with the Reelfoot scarp. It was also revealed that, in addition to vegetative cover, soil moisture conditions strongly influence the contrast between differing soil types of the upper Mississippi embayment in the visible and near infrared spectral region.
