2023-05-10 22:42:24 UTC (2023-05-10) · approx. 11:42 PM UTC+1 local
On May 10, 2023 at 22:42 UTC, a magnitude 4.2 shallow crustal earthquake struck 117 km W of Palai?chora, Greece, at a depth of 44.2 km and coordinates 35.0580°, 22.4107°.
Physical scale: An earthquake of magnitude 4.2 releases seismic energy equivalent to roughly 30 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 476 m — a useful intuition for the size of the slip patch on the fault.
