2024-01-05 21:51:59 UTC (2024-01-05) · approx. 10:51 PM UTC+1 local
On January 5, 2024 at 21:51 UTC, a magnitude 4.2 shallow crustal earthquake struck 19 km SSW of Kalpáki, Greece, at a depth of 47.5 km and coordinates 39.7428°, 20.5036°.
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.
