On April 22, 2025 at 19:10 UTC, a magnitude 4.4 intermediate depth earthquake struck 250 km ENE of Lospalos, Timor Leste, at a depth of 116.8 km and coordinates -7.3274°, 128.9301°.
Physical scale: An earthquake of magnitude 4.4 releases seismic energy equivalent to roughly 60 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 655 m — a useful intuition for the size of the slip patch on the fault.
