2024-03-27 20:30:45 UTC (2024-03-27) · approx. 5:30 AM UTC+9 local
On March 27, 2024 at 20:30 UTC, a magnitude 4.3 shallow crustal earthquake struck in the Volcano Islands, Japan region, at a depth of 34.0 km and coordinates 25.7810°, 142.2884°.
Physical scale: An earthquake of magnitude 4.3 releases seismic energy equivalent to roughly 43 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 558 m — a useful intuition for the size of the slip patch on the fault.
