M4.4 Earthquake 16 km N of Xunchang, China — July 12, 2026
2026-07-12 23:27:55 UTC (3 hours ago) · approx. 6:27 AM UTC+7 local
On July 12, 2026 at 23:27 UTC, a magnitude 4.4 shallow crustal earthquake struck 16 km N of Xunchang, China, at a depth of 58.5 km and coordinates 28.6046°, 104.7010°.
Physical scale: An earthquake of magnitude 4.4 releases seismic energy equivalent to roughly 60 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 655 m — 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 4 days ago 1 km NNW of Xunchang, China. Since the mainshock, the USGS has recorded 4 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 4.4 earthquake near Xunchang, China?
The magnitude 4.4 earthquake that struck 16 km N of Xunchang, China on July 12, 2026 at 23:27 UTC had a depth of 58.5 km. For context, this was a light earthquake commonly felt near the epicenter.
Were there aftershocks?
Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 4.4 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 4.4 earthquake is an aftershock of the larger magnitude 5.0 mainshock that occurred earlier 1 km NNW of Xunchang, 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.
