On May 2, 2023 at 17:56 UTC, a magnitude 4.3 shallow crustal earthquake struck 98 km SSW of Muncar, Indonesia, at a depth of 49.8 km and coordinates -9.3033°, 114.1417°.
Physical scale: An earthquake of magnitude 4.3 releases seismic energy equivalent to roughly 43 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 558 m — a useful intuition for the size of the slip patch on the fault.
