2023-04-15 22:35:28 UTC (2023-04-15) · approx. 8:35 AM UTC+10 local
On April 15, 2023 at 22:35 UTC, a magnitude 4.0 intermediate depth earthquake struck 59 km ENE of Kuril’sk, Russia, at a depth of 141.7 km and coordinates 45.5264°, 148.5138°.
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.
