On July 9, 2020 at 20:40 UTC, a magnitude 4.0 intermediate depth earthquake struck 55 km WNW of Bengkulu, Indonesia, at a depth of 71.2 km and coordinates -3.5504°, 101.8303°.
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.
