M5.2 Earthquake 242 km SSE of Dunhuang, China — June 16, 2026
2026-06-16 09:42:35 UTC (2 hours ago) · approx. 3:42 PM UTC+6 local
Aftershock of the M5.4 mainshock.
On June 16, 2026 at 09:42 UTC, a magnitude 5.2 shallow crustal earthquake struck 242 km SSE of Dunhuang, China, at a depth of 10.0 km and coordinates 38.0579°, 95.4312°. This earthquake was detected by 77 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 416, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.2 releases seismic energy equivalent to roughly 951 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.3 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 5.4 mainshock that occurred 2 hours ago 277 km S of Dunhuang, China. Since the mainshock, the USGS has recorded 0 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 5.2 earthquake near Dunhuang, China?
The magnitude 5.2 earthquake that struck 242 km SSE of Dunhuang, China on June 16, 2026 at 09:42 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 38.0579°, 95.4312°, which is 242 km SSE of Dunhuang, China.
Were there aftershocks?
Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 5.2 earthquakes can continue for days to weeks and gradually diminish over time.
Is this the same earthquake as the M5.4 one earlier?
No. This magnitude 5.2 earthquake is an aftershock of the larger magnitude 5.4 mainshock that occurred earlier 277 km S of Dunhuang, China. 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.
