Earthquakes in China — September 2025

12 earthquakes were recorded in China during September 2025, an average of 0.4 per day.

12 reached magnitude 4 or above and 1 reached magnitude 5 or above. The average focal depth was 13 km.

The month's largest event in China was a magnitude 5.2 earthquake near Hualin, China on 26 September 2025 at 21:49 UTC. A magnitude 5.2 earthquake radiates roughly 951 tons of TNT equivalent in seismic energy.

That is close to the China monthly average of 13 events over the period we cover, and up from the 3 recorded the previous month.

100% of events here are shallow (under 70 km), 0% intermediate (70–300 km) and 0% deep-focus (over 300 km). Almost everything here is crustal. That is characteristic of transform faulting or continental deformation rather than subduction — and it means shaking at the surface is strong for the magnitudes involved.

By band, the catalogue holds 11 in the magnitude 4 range, 1 in the magnitude 5 range.

Activity peaked on 07 September, when 2 events were recorded.

The month's largest events were M5.2 near Hualin, China on 26 September at 10 km; M4.9 near Tumxuk, China on 02 September at 10 km; M4.8 near Hualin, China on 26 September at 10 km.

That is close to the 13 events China averages per month across the 21 months on record.
