2023-05-31 23:22:55 UTC (2023-05-31) · approx. 7:22 AM UTC+8 local
On May 31, 2023 at 23:22 UTC, a magnitude 4.0 intermediate depth earthquake struck 4 km W of Gorontalo, Indonesia, at a depth of 258.9 km and coordinates 0.5389°, 123.0214°.
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.
