On May 25, 2026 at 10:23 UTC, a magnitude 4.9 intermediate depth earthquake struck 224 km NE of Lospalos, Timor Leste, at a depth of 139.2 km and coordinates -7.3309°, 128.6487°. This earthquake was detected by 89 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 369, placing it among routine seismic activity.

Physical scale: An earthquake of magnitude 4.9 releases seismic energy equivalent to roughly 338 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.4 km — a useful intuition for the size of the slip patch on the fault.
