On March 29, 2023 at 22:12 UTC, a magnitude 4.1 intermediate depth earthquake struck 131 km NW of Maubara, Timor Leste, at a depth of 270.5 km and coordinates -7.7107°, 124.4296°.

Physical scale: An earthquake of magnitude 4.1 releases seismic energy equivalent to roughly 21 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 406 m — a useful intuition for the size of the slip patch on the fault.
