2021-05-20 20:21:30 UTC (2021-05-20) · approx. 6:21 AM UTC+10 local
On May 20, 2021 at 20:21 UTC, a magnitude 4.5 shallow crustal earthquake struck near Kuril Islands, at a depth of 67.6 km and coordinates 47.4463°, 153.5462°.
Physical scale: An earthquake of magnitude 4.5 releases seismic energy equivalent to roughly 85 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 767 m — a useful intuition for the size of the slip patch on the fault.
