2021-05-27 16:13:44 UTC (2021-05-27) · approx. 1:13 AM UTC+9 local
On May 27, 2021 at 16:13 UTC, a magnitude 4.2 shallow crustal earthquake struck 65 km E of Vostok, Russia, at a depth of 10.0 km and coordinates 46.3706°, 136.6694°.
Physical scale: An earthquake of magnitude 4.2 releases seismic energy equivalent to roughly 30 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 476 m — a useful intuition for the size of the slip patch on the fault.
