2023-04-03 20:50:32 UTC (2023-04-03) · approx. 4:50 AM UTC+8 local
On April 3, 2023 at 20:50 UTC, a magnitude 5.0 intermediate depth earthquake struck 122 km NNW of Pante Makasar, Timor Leste, at a depth of 181.5 km and coordinates -8.2205°, 123.8573°. This earthquake was detected by 90 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 385, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.0 releases seismic energy equivalent to roughly 477 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.7 km — a useful intuition for the size of the slip patch on the fault.
