On December 25, 2024 at 17:34 UTC, a magnitude 4.0 intermediate depth earthquake struck 246 km ENE of Lospalos, Timor Leste, at a depth of 144.6 km and coordinates -7.4216°, 128.9378°.

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.
