2025-02-03 23:07:32 UTC (2025-02-03) · approx. 12:07 AM UTC+1 local
On February 3, 2025 at 23:07 UTC, a magnitude 2.4 shallow crustal earthquake struck 2 km ESE of Siena, Italy, at a depth of 10.6 km and coordinates 43.3042°, 11.3608°.
Physical scale: An earthquake of magnitude 2.4 releases seismic energy equivalent to roughly 60.0 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 27 m — a useful intuition for the size of the slip patch on the fault.
