2025-01-28 18:40:35 UTC (2025-01-28) · approx. 8:40 PM UTC+2 local
On January 28, 2025 at 18:40 UTC, a magnitude 4.0 shallow crustal earthquake struck 26 km SW of Agía Galíni, Greece, at a depth of 10.0 km and coordinates 34.9391°, 24.4723°.
Physical scale: An earthquake of magnitude 4.0 releases seismic energy equivalent to roughly 15 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 347 m — a useful intuition for the size of the slip patch on the fault.
