On November 13, 2022 at 18:43 UTC, a magnitude 3.0 shallow crustal earthquake struck 4 km SSW of Mooringsport, Louisiana, at a depth of 5.0 km and coordinates 32.6524°, -93.9825°. This earthquake was detected by 26 seismic stations with good location accuracy and was assigned a USGS significance rating of 146, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 3.0 releases seismic energy equivalent to roughly 477 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 71 m — a useful intuition for the size of the slip patch on the fault.
