Early-morning earthquake reported near Summerville

SUMMERVILLE, SC (WCSC) - Scientists measured a small earthquake less than two miles north-northwest of Summerville Friday morning.

The magnitude 1.7 quake occurred at 1:02 a.m., according to the United States Geological Survey, the agency that studies the country's national resources and natural hazards like earthquakes.

A magnitude 1.7 earthquake is considered a "microearthquake" on the Richter scale and is rarely felt by most people, but is usually still recorded on seismographs.

According to Michigan State's UPSeis earth sciences education program, approximately 900,000 earthquakes of this magnitude are measured annually. A quake with a magnitude 3.0 or less is considered "minor."
