2025-10-19 22:59:18 UTC (2025-10-19) · approx. 2:59 AM UTC+4 local
On October 19, 2025 at 22:59 UTC, a magnitude 3.7 shallow crustal earthquake struck 28 km ENE of Tirlyanskiy, Russia, at a depth of 10.0 km and coordinates 54.3524°, 58.9495°.
Physical scale: An earthquake of magnitude 3.7 releases seismic energy equivalent to roughly 5.4 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 215 m — a useful intuition for the size of the slip patch on the fault.
