On April 17, 2025 at 07:26 UTC, a magnitude 4.8 shallow crustal earthquake struck 28 km SW of Lospalos, Timor Leste, at a depth of 22.4 km and coordinates -8.7277°, 126.8377°. This earthquake was detected by 67 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 354, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.8 releases seismic energy equivalent to roughly 239 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.2 km — a useful intuition for the size of the slip patch on the fault.
