On April 23, 2026 at 22:13 UTC, a magnitude 4.6 intermediate depth earthquake struck 280 km ENE of Lospalos, Timor Leste, at a depth of 145.3 km and coordinates -7.1997°, 129.1713°. This earthquake was detected by 41 seismic stations with good location accuracy and was assigned a USGS significance rating of 326, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.6 releases seismic energy equivalent to roughly 120 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 899 m — a useful intuition for the size of the slip patch on the fault.
