2024-10-15 18:49:07 UTC (2024-10-15) · approx. 2:49 AM UTC+8 local
On October 15, 2024 at 18:49 UTC, a magnitude 4.0 shallow crustal earthquake struck 62 km SSE of Miyakojima, Japan, at a depth of 42.8 km and coordinates 24.2931°, 125.6075°.
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.
