On November 7, 2021 at 19:43 UTC, a magnitude 4.4 shallow crustal earthquake struck near Pulau-Pulau Sula, Indonesia, at a depth of 27.7 km and coordinates -2.0519°, 125.6722°.
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.
