DORCHESTER, S.C. (WCIV) -- Two small earthquakes were recorded by The U.S. Geological Survey over the weekend.

The first was a magnitude-1.4 quake that hit just before 7 p.m. Sunday off Old Trolley Road. The epicenter was just northwest of the Summerville Soccer Club, south of the Church of Christ and was 6.8 miles underground.

For those who like to map these events, the coordinates are 32.973°N, 80.182°W.

The second quake happened just seven hours later, just after 2 a.m. Monday off Dorchester Road. The epicenter was southeast of the Kings Grant Golf Club, northwest of the Whitehall Amenity Center, and was 3.7 miles underground. It measured 1.5 on the Richter scale.

The coordinates of the second quake are 32.924°N, 80.142°W.

College of Charleston Associate Professor of Geology Dr. Erin Beutel stresses that the number of quakes experienced in the area vary year by year and that there is no reason to think the small rumbles are leading up to a larger event.

"Earthquakes of this magnitude are so small that they are very unlikely to be felt by people and never cause damage," Dr. Beutel said Tuesday. "Small earthquakes occur on a regular basis on active faults, (those that are still moving and can produce large earthquakes), and are one way that scientists know which faults might produce a large earthquake in the future.  The location of this earthquake in Summerville is consistent with it being part of the fault grouping that caused the magnitude 7.0 earthquake in 1886."
