On May 30, 2024 at 20:08 UTC, a magnitude 4.2 intermediate depth earthquake struck 35 km NE of Sibolga, Indonesia, at a depth of 132.2 km and coordinates 1.9421°, 99.0285°.

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.
