On November 26, 2023 at 21:57 UTC, a magnitude 4.0 shallow crustal earthquake struck 107 km SSE of Waingapu, Indonesia, at a depth of 17.5 km and coordinates -10.5797°, 120.5595°.

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.
