On January 18, 2023 at 15:54 UTC, a magnitude 5.1 shallow crustal earthquake struck 110 km S of ?urrieq, Malta, at a depth of 10.0 km and coordinates 34.8554°, 14.2579°. This earthquake was detected by 193 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 408, placing it among routine seismic activity.

Physical scale: An earthquake of magnitude 5.1 releases seismic energy equivalent to roughly 674 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.0 km — a useful intuition for the size of the slip patch on the fault.
