KERSHAW COUNTY, SC (WIS) – Seismologists reported that an earthquake did occur in Kershaw County Friday afternoon. They said it was a magnitude 2.3 earthquake on the Richter Scale.
The incident happened four miles northeast of Camden around 2:15 p.m.
Here are the distances from various areas where the quake was centered:
4 miles NNE of Camden, South Carolina 29 miles NNW of Sumter, South Carolina 33 miles NE of Columbia, South Carolina 45 miles S of Monroe, North Carolina
A number of residents in that area say they felt shaking or heard a loud explosion.
Some callers initially thought it may have been caused by military planes flying close-by. The North American Aerospace Defense Command - known as NORAD – was practicing flight interception and identification over the eastern part of the state. But NORAD said those drills were completed Thursday and did not extend over into Friday.
