On August 18, 2025 at 20:38 UTC, a magnitude 4.7 deep-focus earthquake struck 130 km NNE of Baukau, Timor Leste, at a depth of 398.1 km and coordinates -7.3281°, 126.7221°. This earthquake was detected by 86 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 341, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.7 releases seismic energy equivalent to roughly 169 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.1 km — a useful intuition for the size of the slip patch on the fault.
