2023-06-19 23:47:14 UTC (2023-06-19) · approx. 8:47 AM UTC+9 local
On June 19, 2023 at 23:47 UTC, a magnitude 4.4 shallow crustal earthquake struck 16 km SSE of Kushima, Japan, at a depth of 63.3 km and coordinates 31.3435°, 131.3027°.
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.
