On June 28, 2026 at 11:35 UTC, a magnitude 4.5 intermediate depth earthquake struck 225 km NE of Lospalos, Timor Leste, at a depth of 165.5 km and coordinates -7.3800°, 128.6950°. This earthquake was detected by 54 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 312, placing it among routine seismic activity.

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.
