Earthquakes in China — March 2025

11 earthquakes were recorded in China during March 2025, an average of 0.4 per day.

11 reached magnitude 4 or above and 1 reached magnitude 5 or above. The average focal depth was 27 km.

The month's largest event in China was a magnitude 5.0 earthquake near Xuyong, China on 24 March 2025 at 11:21 UTC. A magnitude 5.0 earthquake radiates roughly 477 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 5 recorded the previous month.

91% of events here are shallow (under 70 km), 9% 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 10 in the magnitude 4 range, 1 in the magnitude 5 range.

Activity peaked on 25 March, when 3 events were recorded.

The month's largest events were M5.0 near Xuyong, China on 24 March at 10 km; M4.9 near Kuqa, China on 05 March at 10 km; M4.7 near Zhaotong, China on 29 March at 10 km.

That is 16% below the 13 events China averages per month across the 21 months on record.
