On October 1, 2025 at 13:49 UTC, a magnitude 5.6 intermediate depth earthquake struck 199 km NE of Lospalos, Timor Leste, at a depth of 146.8 km and coordinates -7.3220°, 128.3436°. The earthquake was reported felt by 1 personacross nearby locations, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 3.4 (light). The USGS PAGER system issued a green alert level for this event, indicating no significant casualties or damage expected. This earthquake was detected by 144 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 483, placing it among routine seismic activity. The nearest populated place is Tiakur (population 0).

Physical scale: An earthquake of magnitude 5.6 releases seismic energy equivalent to roughly 4 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 4.4 km — a useful intuition for the size of the slip patch on the fault.
