On May 31, 2024 at 23:37 UTC, a magnitude 4.4 shallow crustal earthquake struck 22 km N of Mlowo, Tanzania, at a depth of 7.3 km and coordinates -8.7932°, 32.9927°.

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.
