Irmo, SC -- A minor earthquake hit South Carolina this morning, rumbling some nerves but causing no damage.
The earthquake registered 3.1 on the Richter scale hitting near Irmo, which is just west of Columbia.
The US Geological Survey confirms the minor earthquake occurred at 9:21am.
A geologist at the University of South Carolina, Pradeep Talwani says he's still reviewing information from his equipment.
Viewers for WLTX, the Gannett-owned TV station in Columbia, SC e-mailed the station saying they felt the quake. One person living in Fletcher, NC also e-mailed the station saying they felt a tremble.
People in downtown Columbia also felt the tremor. No damage has been reported.
The Columbia Fire Department first told people construction crews doing some blasting at a local dam caused the rumbles. However, no one was blasting in the area.
An earthquake of less than 3.5 on the Richter Scale is generally not felt and rarely causes damage.
