Felt by 116 people across surrounding communities.
On September 15, 2024 at 22:01 UTC, a magnitude 2.5 shallow crustal earthquake struck 6 km E of Elgin, South Carolina, at a depth of 2.3 km and coordinates 34.1743°, -80.7247°. This earthquake was detected by 16 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 136, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 2.5 releases seismic energy equivalent to roughly 84.8 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 32 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.
