2025-05-11 22:23:47 UTC (2025-05-11) · approx. 6:23 AM UTC+8 local
On May 11, 2025 at 22:23 UTC, a magnitude 4.0 shallow crustal earthquake struck 117 km N of Sanana, Indonesia, at a depth of 54.9 km and coordinates -1.0068°, 125.8137°.
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.
