On August 18, 2023 at 18:29 UTC, a magnitude 4.4 shallow crustal earthquake struck 118 km S of Jatiroto, Indonesia, at a depth of 16.3 km and coordinates -8.9583°, 111.0824°.
Physical scale: An earthquake of magnitude 4.4 releases seismic energy equivalent to roughly 60 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 655 m — a useful intuition for the size of the slip patch on the fault.
