On February 8, 2023 at 18:58 UTC, a magnitude 4.1 shallow crustal earthquake struck 19 km ENE of Bcharré, Lebanon, at a depth of 10.0 km and coordinates 34.2985°, 36.2101°. This earthquake was detected by 59 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 269, placing it among routine seismic activity.

Physical scale: An earthquake of magnitude 4.1 releases seismic energy equivalent to roughly 21 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 406 m — a useful intuition for the size of the slip patch on the fault.
