2022-08-03 20:03:18 UTC (2022-08-03) · approx. 5:03 AM UTC+9 local
On August 3, 2022 at 20:03 UTC, a magnitude 4.0 shallow crustal earthquake struck 281 km ENE of Lospalos, Timor Leste, at a depth of 50.9 km and coordinates -7.7524°, 129.4369°.
Physical scale: An earthquake of magnitude 4.0 releases seismic energy equivalent to roughly 15 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 347 m — a useful intuition for the size of the slip patch on the fault.
