On July 25, 2024 at 20:32 UTC, a magnitude 5.5 intermediate depth earthquake struck 225 km NE of Lospalos, Timor Leste, at a depth of 144.0 km and coordinates -7.3691°, 128.6810°. The earthquake was reported felt by 3 peopleacross nearby locations, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 4.0 (moderate). The USGS PAGER system issued a green alert level for this event, indicating no significant casualties or damage expected. This earthquake was detected by 121 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 466, placing it among routine seismic activity. The nearest populated place is Tiakur (population 0).

Physical scale: An earthquake of magnitude 5.5 releases seismic energy equivalent to roughly 3 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 3.8 km — a useful intuition for the size of the slip patch on the fault.
