On September 15, 2025 at 09:55 UTC, a magnitude 5.1 shallow crustal earthquake struck 234 km SE of Birżebbuġa, Malta, at a depth of 10.0 km and coordinates 34.3393°, 16.3558°. This earthquake was detected by 123 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 403, 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.
