On May 26, 2026 at 01:35 UTC, a magnitude 4.1 deep-focus earthquake struck 239 km WSW of Ambon, Indonesia, at a depth of 394.1 km and coordinates -4.2400°, 126.0995°.

Physical scale: An earthquake of magnitude 4.1 releases seismic energy equivalent to roughly 21 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 406 m — a useful intuition for the size of the slip patch on the fault.
