Abstract

A SPOT satellite image of the Charleston, South Carolina, area revealed a linear feature, the Woodstock lineament, that may be the surface expression of a seismogenic fault of the 1886 Charleston earthquake. An enhancement of the SPOT image reveals a linear, 5 km wide band on the east side of the lineament that extends at least 65 km in a north-northeast direction and coincides with a part of the axis of the highest intensity isoseismal contours of the Charleston earthquake. Corroborative geologic, geodetic, and geophysical data suggest that the lineament and associated band may be the result of ongoing tectonic activity on the Woodstock fault inferred from seismicity.
