Stations of the "MPSSZ"
The Middleton Place/Summerville Seismic Zone is the most active area of tectonic seismicity in South Carolina. Annual totals average 12 to 15 events of magnitude 1.0Ml or greater with twice that number of quakes less than 1.0, many too small to be located accurately. Research continues on the mechanisms at work in the Charleston area. One active fault has already been established along the Ashley River(Ashley River Fault)and recent work supports the concept of another fault running near parallel to the coastline from SW of Charleston to the NE towards Lake Moultrie (Woodstock Fault).
