On March 19, 2025 at 21:57 UTC, a magnitude 4.2 shallow crustal earthquake struck 104 km SE of Sanana, Indonesia, at a depth of 37.3 km and coordinates -2.7264°, 126.6368°.

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.
