2022-04-07 22:57:25 UTC (2022-04-07) · approx. 8:57 AM UTC+10 local
On April 7, 2022 at 22:57 UTC, a magnitude 4.3 shallow crustal earthquake struck 84 km SSE of Kushiro, Japan, at a depth of 27.0 km and coordinates 42.2434°, 144.6543°.
Physical scale: An earthquake of magnitude 4.3 releases seismic energy equivalent to roughly 43 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 558 m — a useful intuition for the size of the slip patch on the fault.
