2025-04-27 20:23:35 UTC (2025-04-27) · approx. 8:23 AM UTC-12 local
On April 27, 2025 at 20:23 UTC, a magnitude 3.3 shallow crustal earthquake struck 140 km WNW of Lorino, Russia, at a depth of 7.0 km and coordinates 65.9441°, -174.5724°.
Physical scale: An earthquake of magnitude 3.3 releases seismic energy equivalent to roughly 1.3 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 114 m — a useful intuition for the size of the slip patch on the fault.
