On January 8, 2023 at 22:54 UTC, a magnitude 4.0 intermediate depth earthquake struck 72 km E of Maumere, Indonesia, at a depth of 125.9 km and coordinates -8.6980°, 122.8654°.
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.
