2020-09-19 23:38:33 UTC (2020-09-19) · approx. 7:38 AM UTC+8 local
On September 19, 2020 at 23:38 UTC, a magnitude 4.0 shallow crustal earthquake struck 34 km NNW of Pante Makasar, Timor Leste, at a depth of 68.5 km and coordinates -8.9215°, 124.2454°.
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.
