On August 27, 2026 at 21:07 UTC, a magnitude 5.9 shallow crustal earthquake struck 144 km N of Caluula, Somalia, at a depth of 10.0 km and coordinates 13.2595°, 50.5603°.0 The USGS PAGER system issued a green alert level for this event, indicating no significant casualties or damage expected. This earthquake was detected by 127 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 536, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.9 releases seismic energy equivalent to roughly 11 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 7.1 km — a useful intuition for the size of the slip patch on the fault.
