2023-06-03 07:17:46 UTC (2023-06-03) · approx. 10:17 AM UTC+3 local
On June 3, 2023 at 07:17 UTC, a magnitude 5.8 shallow crustal earthquake struck 164 km N of Las Khorey, Somalia, at a depth of 10.0 km and coordinates 12.6434°, 48.1757°. The USGS PAGER system issued a green alert level for this event, indicating no significant casualties or damage expected. This earthquake was detected by 206 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 518, placing it among routine seismic activity. The nearest populated place is Rudum (population 0).
Physical scale: An earthquake of magnitude 5.8 releases seismic energy equivalent to roughly 8 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 6.1 km — a useful intuition for the size of the slip patch on the fault.
