2022-11-15 23:43:11 UTC (2022-11-15) · approx. 9:43 AM UTC+10 local
On November 15, 2022 at 23:43 UTC, a magnitude 4.2 intermediate depth earthquake struck in the Volcano Islands, Japan region, at a depth of 287.1 km and coordinates 22.0316°, 142.7216°.
Physical scale: An earthquake of magnitude 4.2 releases seismic energy equivalent to roughly 30 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 476 m — a useful intuition for the size of the slip patch on the fault.
