2022-06-03 18:29:44 UTC (2022-06-03) · approx. 2:29 AM UTC+8 local
On June 3, 2022 at 18:29 UTC, a magnitude 4.0 shallow crustal earthquake struck 132 km WNW of Naha, Japan, at a depth of 7.3 km and coordinates 26.7534°, 126.4911°.
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.
