2025-04-17 21:57:36 UTC (2025-04-17) · approx. 10:57 PM UTC+1 local
On April 17, 2025 at 21:57 UTC, a magnitude 3.3 shallow crustal earthquake struck 13 km NE of Sliema, Malta, at a depth of 10.0 km and coordinates 36.0117°, 14.5875°.
Physical scale: An earthquake of magnitude 3.3 releases seismic energy equivalent to roughly 1.3 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 114 m — a useful intuition for the size of the slip patch on the fault.
