Earthquakes in Taiwan — December 2025

12 earthquakes were recorded in Taiwan during December 2025, an average of 0.4 per day.

12 reached magnitude 4 or above and 5 reached magnitude 5 or above. The average focal depth was 29 km.

The month's largest event in Taiwan was a magnitude 6.7 earthquake near Yilan, Taiwan on 27 December 2025 at 15:05 UTC. A magnitude 6.7 earthquake radiates roughly 169,203 tons of TNT equivalent in seismic energy.

That is well above the Taiwan monthly average of 7 events over the period we cover — an unusually active month, and up from the 8 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 7 in the magnitude 4 range, 2 in the magnitude 5 range, 3 in the magnitude 6 range.

Activity peaked on 27 December, when 3 events were recorded.

2 event(s) this month carry a USGS link to NOAA tsunami information; the flag does not indicate whether a tsunami occurred.

The month's largest events were M6.7 near Yilan, Taiwan on 27 December at 35 km; M6.6 near Yilan, Taiwan on 27 December at 68 km; M6.0 near 2025 Taitung, Taiwan on 24 December at 10 km.

That is 83% above the 7 events Taiwan averages per month across the 21 months on record.

This month also holds the strongest earthquake recorded in Taiwan in our entire catalogue.
