2020-06-04 19:59:04 UTC (2020-06-04) · approx. 5:59 AM UTC+10 local
On June 4, 2020 at 19:59 UTC, a magnitude 4.1 shallow crustal earthquake struck in the Bonin Islands, Japan region, at a depth of 2.3 km and coordinates 28.0700°, 142.8861°.
Physical scale: An earthquake of magnitude 4.1 releases seismic energy equivalent to roughly 21 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 406 m — a useful intuition for the size of the slip patch on the fault.
