2024-05-31 23:20:56 UTC (2024-05-31) · approx. 9:20 AM UTC+10 local
On May 31, 2024 at 23:20 UTC, a magnitude 4.2 shallow crustal earthquake struck in the Volcano Islands, Japan region, at a depth of 10.0 km and coordinates 22.9161°, 143.8660°.
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.
