On September 12, 2022 at 21:37 UTC, a magnitude 4.1 shallow crustal earthquake struck 147 km S of Dompu, Indonesia, at a depth of 67.9 km and coordinates -9.8593°, 118.6419°.

Physical scale: An earthquake of magnitude 4.1 releases seismic energy equivalent to roughly 21 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 406 m — a useful intuition for the size of the slip patch on the fault.
