Felt by 164 people across surrounding communities.
On January 27, 2022 at 23:47 UTC, a magnitude 2.1 shallow crustal earthquake struck 7 km SSW of Lugoff, South Carolina, at a depth of 1.0 km and coordinates 34.1653°, -80.7085°. This earthquake was detected by 16 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 137, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 2.1 releases seismic energy equivalent to roughly 23.6 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 18 m — a useful intuition for the size of the slip patch on the fault.
The epicenter is located in South Carolina, a region characterized by the Middleton Place-Summerville Seismic Zone near Charleston, site of the destructive 1886 M7.3 earthquake. View all earthquakes in South Carolina.
