On July 4, 2023 at 22:19 UTC, a magnitude 4.4 deep-focus earthquake struck 155 km N of Likisá, Timor Leste, at a depth of 472.2 km and coordinates -7.1919°, 125.2041°.

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.
