On December 30, 2020 at 20:29 UTC, a magnitude 4.5 deep-focus earthquake struck 208 km NNE of Lospalos, Timor Leste, at a depth of 393.4 km and coordinates -6.6907°, 127.4441°.

Physical scale: An earthquake of magnitude 4.5 releases seismic energy equivalent to roughly 85 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 767 m — a useful intuition for the size of the slip patch on the fault.
