On January 19, 2021 at 05:01 UTC, a magnitude 5.4 deep-focus earthquake struck 137 km N of Likisá, Timor Leste, at a depth of 428.1 km and coordinates -7.3486°, 125.2798°. The USGS PAGER system issued a green alert level for this event, indicating no significant casualties or damage expected. The nearest populated place is Alemba (population 0).
Physical scale: An earthquake of magnitude 5.4 releases seismic energy equivalent to roughly 2 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 3.2 km — a useful intuition for the size of the slip patch on the fault.
