On June 27, 2020 at 22:13 UTC, a magnitude 2.7 shallow crustal earthquake struck 6 km WSW of Chickamauga, Georgia, at a depth of 12.0 km and coordinates 34.8593°, -85.3565°. This earthquake was detected by 28 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 114, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 2.7 releases seismic energy equivalent to roughly 153 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 42 m — a useful intuition for the size of the slip patch on the fault.
