On March 29, 2025 at 15:57 UTC, a magnitude 4.2 intermediate depth earthquake struck near Pulau Pulau Tanimbar, Indonesia, at a depth of 139.9 km and coordinates -7.0741°, 130.1855°.

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.
