On January 16, 2023 at 18:23 UTC, a magnitude 4.3 shallow crustal earthquake struck 4 km SSW of Klos, Albania, at a depth of 9.4 km and coordinates 41.4680°, 20.0656°.

Physical scale: An earthquake of magnitude 4.3 releases seismic energy equivalent to roughly 43 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 558 m — a useful intuition for the size of the slip patch on the fault.
