Small magnitude 3.3 quake hits 5 miles southeast of Summerville, South Carolina, United States early evening
3.3 quake 27 Sep 6:21 pm (GMT -4)
3.3 quake 27 Sep 6:21 pm (GMT -4)
A magnitude 3.3 earthquake near Summerville, Dorchester County, South Carolina, USA, was reported 32 minutes ago by the United States Geological Survey, considered the key international and national agency that monitors seismic activity in the US. The earthquake occurred at a very shallow depth of 4 miles beneath the epicenter early evening on Monday, September 27th, 2021, at 6:21 pm local time. Magnitude and other quake parameters can still change in the coming hours as the agency continues to process seismic data.
Our monitoring service identified a second report from the European-Mediterranean Seismological Centre (EMSC) which listed the quake at magnitude 3.3 as well.
Based on the preliminary seismic data, the quake should not have caused any significant damage, but was probably felt by many people as light vibration in the area of the epicenter.
Weak shaking might have been felt in Centerville (pop. 5,300) located 4 miles from the epicenter, Ladson (pop. 13,800) 4 miles away, and Summerville (pop. 48,800) 5 miles away.
Other towns or cities near the epicenter where the quake might have been felt as very weak shaking include Goose Creek (pop. 40,600) located 7 miles from the epicenter, Hanahan (pop. 18,000) 8 miles away, North Charleston (pop. 108,300) 12 miles away, and Mt. Pleasant (pop. 81,300) 20 miles away.
