On January 27, 2024 at 20:39 UTC, a magnitude 3.6 shallow crustal earthquake struck 4 km SSW of Hall Summit, Louisiana, at a depth of 8.9 km and coordinates 32.1414°, -93.3221°. The earthquake was reported felt by 35 peopleacross nearby locations, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 4.2 (moderate). This earthquake was detected by 14 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 214, placing it among routine seismic activity.

Physical scale: An earthquake of magnitude 3.6 releases seismic energy equivalent to roughly 3.8 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 184 m — a useful intuition for the size of the slip patch on the fault.
