On August 27, 2026 at 21:07 UTC, a magnitude 6.0 shallow crustal earthquake struck 145 km N of Caluula, Somalia, at a depth of 10.0 km and coordinates 13.2654°, 50.5425°. The USGS PAGER system issued a green alert level for this event, indicating no significant casualties or damage expected. This earthquake was detected by 92 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 554, placing it among routine seismic activity. The nearest populated place is Ash Shihr (population 68,313).
Physical scale: An earthquake of magnitude 6.0 releases seismic energy equivalent to roughly 15 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 8.3 km — a useful intuition for the size of the slip patch on the fault.
