A series of small earthquakes northwest of Columbia, South Carolina, are caused by a man-made lake built more than 40 years ago, according to geologists.
The tiny temblors — magnitude 2.0 and less — are jangling nerves near South Carolina’s Lake Monticello, according to The State newspaper, but the tremors are not unprecedented. The reservoir set off a series of minor earthquakeswhen it was first filled in the late 1970s. Another small swarm occurred between 1996 and 1999. Since Oct. 25, there have been seven earthquakes detected near the lake, according to the South Carolina Department of Natural Resources.
