On June 12, 2025 at 17:29 UTC, a magnitude 4.5 intermediate depth earthquake struck 242 km ENE of Lospalos, Timor Leste, at a depth of 138.2 km and coordinates -7.3780°, 128.8768°. This earthquake was detected by 38 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.
