On November 24, 2020 at 18:36 UTC, a magnitude 4.4 shallow crustal earthquake struck 140 km NNE of Tobelo, Indonesia, at a depth of 40.9 km and coordinates 2.9205°, 128.4578°.

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.
