earthquake summerville sc was reported by the US Geological Survey as a 2.9 magnitude event. USGS placed the epicenter about 3.7 miles south-southeast of Centerville in Dorchester County. WIS said the tremor occurred around 10:37 p.m. and had a depth near 5.2 kilometers.
WIS noted the USGS briefly listed a 3.2 magnitude before amending the reading to 2.9. That revision followed an initial WCSC report that described a 3.2 magnitude event about 4.7 miles from Ladson just before 10:40 p.m.
WCSC reported a depth of 10 kilometers for its initial measurement while WIS and USGS cited the shallower depth near 5.2 kilometers. The differing numbers reflect preliminary seismic data that outlets described as subject to amendment.
Residents reported hearing pops and feeling shaking in Goose Creek, Hanahan, Ladson, North Charleston and Summerville, according to WIS. WIS said people posted accounts of popping sounds and brief rattling across multiple Low Country communities.
Local Impact And Context
No injuries have been reported, WCSC said, and authorities called the episode a developing story. WCSC added that the event came days after a separate 2.3 magnitude quake in the Summerville area.
WIS cited USGS guidance that earthquakes near magnitude 2.5 can be felt by people. It added that people commonly notice quakes above about magnitude 3.0, which helps explain why residents across Dorchester and nearby towns reported feeling this tremor.
The reports from USGS, WIS and WCSC together show preliminary seismic measurements that differed on magnitude and depth. Local officials and news outlets continued to monitor the situation as details remained subject to official updates.
