On August 13, 2020 at 14:54 UTC, a magnitude 5.1 shallow crustal earthquake struck 64 km NNE of Kilindoni, Tanzania, at a depth of 10.0 km and coordinates -7.3547°, 39.8115°.
Physical scale: An earthquake of magnitude 5.1 releases seismic energy equivalent to roughly 674 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.0 km — a useful intuition for the size of the slip patch on the fault.
