M4.9 Earthquake 148 km NNW of Kilmia, Yemen — October 24, 2026
2026-10-24 11:20:27 UTC (1 hour ago) · approx. 2:20 PM UTC+3 local
Aftershock of the M5.2 mainshock.
On October 24, 2026 at 11:20 UTC, a magnitude 4.9 shallow crustal earthquake struck 148 km NNW of Kilmia, Yemen, at a depth of 10.0 km and coordinates 13.3207°, 51.5108°. This earthquake was detected by 52 seismic stations with good location accuracy and was assigned a USGS significance rating of 369, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.9 releases seismic energy equivalent to roughly 338 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.4 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 27 days ago 150 km NW of Kilmia, Yemen. Since the mainshock, the USGS has recorded 2 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 4.9 earthquake near Kilmia, Yemen?
The magnitude 4.9 earthquake that struck 148 km NNW of Kilmia, Yemen on October 24, 2026 at 11:20 UTC had a depth of 10.0 km. For context, this was a light earthquake commonly felt near the epicenter.
Where did the earthquake occur?
The earthquake epicenter was located at 13.3207°, 51.5108°, which is 148 km NNW of Kilmia, Yemen.
Were there aftershocks?
Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 4.9 earthquakes can continue for several days and gradually diminish over time.
Is this the same earthquake as the M5.2 one earlier?
No. This magnitude 4.9 earthquake is an aftershock of the larger magnitude 5.2 mainshock that occurred earlier 150 km NW of Kilmia, Yemen. Aftershocks are smaller earthquakes triggered by stress changes from the mainshock.
