2025-02-14 17:25:08 UTC (2025-02-14) · approx. 2:25 AM UTC+9 local
On February 14, 2025 at 17:25 UTC, a magnitude 4.0 shallow crustal earthquake struck in the Volcano Islands, Japan region, at a depth of 39.1 km and coordinates 23.9796°, 142.4651°.
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.
