On December 7, 2023 at 19:00 UTC, a magnitude 4.0 shallow crustal earthquake struck 2 km W of Pelabuhanratu, Indonesia, at a depth of 9.0 km and coordinates -6.9850°, 106.5272°.

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.
