On January 27, 2025 at 10:50 UTC, a magnitude 4.9 intermediate depth earthquake struck 270 km ENE of Lospalos, Timor Leste, at a depth of 125.0 km and coordinates -7.2631°, 129.1024°. This earthquake was detected by 79 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 369, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.9 releases seismic energy equivalent to roughly 338 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.4 km — a useful intuition for the size of the slip patch on the fault.
