Fairfield County, SC (WLTX) - The U.S. Geological Survey says a minor earthquake happened here in the Midlands late Tuesday night.

The 1.6 magnitude quake, which happened just after 10 p.m., was centered 10.5 miles north of Chapin, according to experts. A map posted on the agency's website showed that location is in the Monticello Reservoir, just north of Jenkinsville.

The quake occurred about 3.2 miles below the surface.

It's unknown if anyone felt the quake, but it would have been very difficult: a 1.6 magnitude is very low on the scale, almost outside of the range that people would notice.
