On November 9, 2023 at 22:05 UTC, a magnitude 4.2 intermediate depth earthquake struck 70 km N of Labuha, Indonesia, at a depth of 158.1 km and coordinates 0.0065°, 127.3816°.
Physical scale: An earthquake of magnitude 4.2 releases seismic energy equivalent to roughly 30 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 476 m — a useful intuition for the size of the slip patch on the fault.
