On September 15, 2026 at 23:46 UTC, a magnitude 4.7 shallow crustal earthquake struck 157 km N of Caluula, Somalia, at a depth of 10.0 km and coordinates 13.3907°, 50.7844°. This earthquake was detected by 41 seismic stations with good location accuracy and was assigned a USGS significance rating of 340, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.7 releases seismic energy equivalent to roughly 169 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.1 km — a useful intuition for the size of the slip patch on the fault.
