On September 5, 2023 at 15:42 UTC, a magnitude 5.1 shallow crustal earthquake struck 37 km SSE of Ikungi, Tanzania, at a depth of 10.0 km and coordinates -5.4349°, 34.9283°. This earthquake was detected by 64 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 400, placing it among routine seismic activity.
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.
