M4.7 Earthquake 160 km SE of Khovd, Mongolia — May 8, 2026
2026-05-08 11:38:55 UTC (10 hours ago) · approx. 5:38 PM UTC+6 local
Felt by 1 person across nearby locations. Aftershock of the M5.5 mainshock.
On May 8, 2026 at 11:38 UTC, a magnitude 4.7 shallow crustal earthquake struck 160 km SE of Khovd, Mongolia, at a depth of 10.0 km and coordinates 46.8298°, 92.8746°. This earthquake was detected by 63 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 340, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.7 releases seismic energy equivalent to roughly 169 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.1 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 5.5 mainshock that occurred 12 days ago 163 km SE of Khovd, Mongolia. 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 4.7 earthquake near Khovd, Mongolia?
The magnitude 4.7 earthquake that struck 160 km SE of Khovd, Mongolia on May 8, 2026 at 11:38 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 46.8298°, 92.8746°, which is 160 km SE of Khovd, Mongolia.
Were there aftershocks?
Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 4.7 earthquakes can continue for several days and gradually diminish over time.
Is this the same earthquake as the M5.5 one earlier?
No. This magnitude 4.7 earthquake is an aftershock of the larger magnitude 5.5 mainshock that occurred earlier 163 km SE of Khovd, Mongolia. Aftershocks are smaller earthquakes triggered by stress changes from the mainshock.
What should I do after an earthquake?
If you were in the affected area: check yourself and others for injuries, inspect your home for damage, and be prepared for aftershocks. For detailed guidance, see our earthquake safety guide and emergency planning resources.
