M4.0 Earthquake near Kuril Islands — June 10, 2021
2021-06-10 18:02:33 UTC (2021-06-10) · approx. 4:02 AM UTC+10 local
On June 10, 2021 at 18:02 UTC, a magnitude 4.0 shallow crustal earthquake struck near Kuril Islands, at a depth of 35.0 km and coordinates 46.6018°, 152.7015°.
Physical scale: An earthquake of magnitude 4.0 releases seismic energy equivalent to roughly 15 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 347 m — a useful intuition for the size of the slip patch on the fault.
