On November 19, 2020 at 15:51 UTC, a magnitude 4.0 shallow crustal earthquake struck 161 km WNW of Tobelo, Indonesia, at a depth of 59.5 km and coordinates 2.4383°, 126.7434°.
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.
