On May 25, 2021 at 20:38 UTC, a magnitude 4.3 shallow crustal earthquake struck 18 km ENE of Gisenyi, Rwanda, at a depth of 10.0 km and coordinates -1.6688°, 29.4184°.
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.
