On September 10, 2023 at 21:46 UTC, a magnitude 4.5 shallow crustal earthquake struck 215 km N of Likisá, Timor Leste, at a depth of 10.6 km and coordinates -6.6601°, 125.0518°. This earthquake was detected by 25 seismic stations with good 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.
