M4.7 Earthquake 5 km N of Bowangshan, China — September 26, 2026
2026-09-26 18:31:42 UTC (54 min ago) · approx. 1:31 AM UTC+7 local
Aftershock of the M5.0 mainshock.
On September 26, 2026 at 18:31 UTC, a magnitude 4.7 shallow crustal earthquake struck 5 km N of Bowangshan, China, at a depth of 10.0 km and coordinates 28.3596°, 105.0553°. This earthquake was detected by 47 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 5.0 mainshock that occurred 19 hours ago 15 km NNW of Xunchang, China. 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 4.7 earthquake near Bowangshan, China?
The magnitude 4.7 earthquake that struck 5 km N of Bowangshan, China on September 26, 2026 at 18:31 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 28.3596°, 105.0553°, which is 5 km N of Bowangshan, China.
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 M5.0 one earlier?
No. This magnitude 4.7 earthquake is an aftershock of the larger magnitude 5.0 mainshock that occurred earlier 15 km NNW of Xunchang, China. Aftershocks are smaller earthquakes triggered by stress changes from the mainshock.
