On May 5, 2026 at 01:29 UTC, a magnitude 4.2 intermediate depth earthquake struck 266 km ENE of Lospalos, Timor Leste, at a depth of 84.6 km and coordinates -7.6079°, 129.2399°.

Physical scale: An earthquake of magnitude 4.2 releases seismic energy equivalent to roughly 30 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 476 m — a useful intuition for the size of the slip patch on the fault.
