A 1.5-magnitude earthquake and a 1.4-magnitude earthquake were recorded near the Ashley River on Sunday.
According to the United States Geological Survey, the first small earthquake was recorded just after 2 a.m. Records show the site of the earthquake to be four miles southwest of Ladson and six miles southeast of Summerville.
The next earthquake was recorded just before 7 p.m. two miles south of Summerville and two miles southwest on Lincolnville.
The last earthquake recorded in the area was a little over a month ago. On early Jan. 29, a 1.5-magnitude earthquake was recorded in the area of Dogwood and Ashley River roads.
It has been more than 100 years since Charleston suffered one of the most devastating earthquakes in U.S. history in 1886, but smaller earthquakes are not uncommon.
Officials say South Carolina has about a dozen small earthquakes a year.
