On November 8, 2020 at 20:54 UTC, a magnitude 4.4 shallow crustal earthquake struck 49 km NNE of Mamuju, Indonesia, at a depth of 56.0 km and coordinates -2.2859°, 119.1054°.
Physical scale: An earthquake of magnitude 4.4 releases seismic energy equivalent to roughly 60 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 655 m — a useful intuition for the size of the slip patch on the fault.
