M5.1 Earthquake 147 km N of Caluula, Somalia — June 25, 2026
2026-06-25 03:53:24 UTC (2026-06-25) · approx. 6:53 AM UTC+3 local
Aftershock of the M5.2 mainshock.
On June 25, 2026 at 03:53 UTC, a magnitude 5.1 shallow crustal earthquake struck 147 km N of Caluula, Somalia, at a depth of 10.0 km and coordinates 13.2794°, 50.9999°. This earthquake was detected by 135 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.
This earthquake is part of an ongoing aftershock sequence following the magnitude 5.2 mainshock that occurred 6 days ago 148 km NW of Kilmia, Yemen. Since the mainshock, the USGS has recorded 1 aftershocks in this area. Aftershock activity is expected to continue for days to weeks as stresses on surrounding faults redistribute.

Common Questions
How strong was the magnitude 5.1 earthquake near Caluula, Somalia?
The magnitude 5.1 earthquake that struck 147 km N of Caluula, Somalia on June 25, 2026 at 03:53 UTC had a depth of 10.0 km. For context, this was a moderate earthquake that could be widely felt.
Where did the earthquake occur?
The earthquake epicenter was located at 13.2794°, 50.9999°, which is 147 km N of Caluula, Somalia.
Were there aftershocks?
Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 5.1 earthquakes can continue for days to weeks and gradually diminish over time.
Is this the same earthquake as the M5.2 one earlier?
No. This magnitude 5.1 earthquake is an aftershock of the larger magnitude 5.2 mainshock that occurred earlier 148 km NW of Kilmia, Yemen. Aftershocks are smaller earthquakes triggered by stress changes from the mainshock.
