M2.5 Earthquake near Tennessee — March 15, 2023
2023-03-15 22:46:04 UTC (2023-03-15) · approx. 4:46 PM UTC-6 local
On March 15, 2023 at 22:46 UTC, a magnitude 2.5 shallow crustal earthquake struck near Tennessee, at a depth of 22.2 km and coordinates 35.6637°, -84.0738°.
Physical scale: An earthquake of magnitude 2.5 releases seismic energy equivalent to roughly 76.5 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 31 m — a useful intuition for the size of the slip patch on the fault.
