2023-05-30 20:38:44 UTC (2023-05-30) · approx. 6:38 AM UTC+10 local
On May 30, 2023 at 20:38 UTC, a magnitude 4.1 shallow crustal earthquake struck 67 km E of Shikotan, Russia, at a depth of 57.2 km and coordinates 43.9180°, 147.5477°.
Physical scale: An earthquake of magnitude 4.1 releases seismic energy equivalent to roughly 21 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 406 m — a useful intuition for the size of the slip patch on the fault.
