2020-11-13 22:08:52 UTC (2020-11-13) · approx. 7:08 AM UTC+9 local
On November 13, 2020 at 22:08 UTC, a magnitude 4.4 shallow crustal earthquake struck in the Volcano Islands, Japan region, at a depth of 15.8 km and coordinates 25.3799°, 142.3377°.
Physical scale: An earthquake of magnitude 4.4 releases seismic energy equivalent to roughly 60 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 655 m — a useful intuition for the size of the slip patch on the fault.
