River anomalies observed within this zone include river bends that are convex toward the north- northeast, incised channels, changes in river patterns, and convex-upward longitudinal profiles. Analyses of geologic and geophysical data further indicate that these surface features may be the result of ongoing tectonic uplift along a north-northeast-trending fault zone possibly associated with recent seismicity near Charleston.
