On March 4, 2026 at 09:31 UTC, a magnitude 4.7 intermediate depth earthquake struck 239 km ENE of Lospalos, Timor Leste, at a depth of 135.5 km and coordinates -7.4023°, 128.8582°. This earthquake was detected by 72 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.
