Small earthquake reported in Summerville Monday night

SUMMERVILLE, SC (WCSC) - A minor earthquake struck the Summerville area Monday night, according to the Center for Earthquake Research and Information.

The magnitude 1.8 event, dubbed a "micro earthquake," occurred at 6:13 p.m. and was centered one mile northwest of Summerville, and 23 miles northwest of Charleston.

According to Michigan Tech, quakes measuring a 2.5 or less on the Richter scale are usually not felt but can be measured on a seismograph, a device that provides a graphic representation of ground motion.

Experts estimate approximately 900,000 quakes of that intensity occur annually.

A devastating earthquake struck Charleston on the evening of August 31, 1886, and experts have estimated that it would have measured as high as a 7.3 on the modern Richter scale. Sixty people died in that quake and damage was estimated at the equivalent of $200 billion in modern dollars.
