2020-11-13 22:18:15 UTC (2020-11-13) · approx. 8:18 AM UTC+10 local
On November 13, 2020 at 22:18 UTC, a magnitude 4.3 shallow crustal earthquake struck 64 km E of Severo-Kuril’sk, Russia, at a depth of 69.3 km and coordinates 50.7149°, 157.0441°.
Physical scale: An earthquake of magnitude 4.3 releases seismic energy equivalent to roughly 43 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 558 m — a useful intuition for the size of the slip patch on the fault.
