On April 17, 2023 at 22:17 UTC, a magnitude 4.2 shallow crustal earthquake struck 82 km SSE of Karpathos, Greece, at a depth of 50.0 km and coordinates 34.8759°, 27.6968°.
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.
