On March 23, 2023 at 07:56 UTC, a magnitude 4.7 intermediate depth earthquake struck 134 km NE of Lospalos, Timor Leste, at a depth of 136.6 km and coordinates -7.6686°, 127.8664°. This earthquake was detected by 41 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 340, 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.
