2021-03-17 19:44:23 UTC (2021-03-17) · approx. 7:44 AM UTC-12 local
On March 17, 2021 at 19:44 UTC, a magnitude 3.0 shallow crustal earthquake struck 143 km W of Lorino, Russia, at a depth of 10.0 km and coordinates 65.6126°, -174.8077°.
Physical scale: An earthquake of magnitude 3.0 releases seismic energy equivalent to roughly 477 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 71 m — a useful intuition for the size of the slip patch on the fault.
