Earthquakes in Taiwan

Seismic activity in Taiwan is moderate by global standards, with 6 events recorded in the past 30 days, and 28 of the events on record reached magnitude 5 or above — the level at which damage becomes a genuine concern for vulnerable construction. Taiwan sits on the Pacific Ring of Fire, the belt of subduction zones responsible for roughly 90% of the world's earthquakes.

138 earthquakes have been recorded in Taiwan in our catalogue, 6 of them in the past 30 days.

The average magnitude is 4.6 and the average focal depth 27 km. 134 events reached magnitude 4 or above and 28 reached magnitude 5 or above.

The strongest earthquake recorded in Taiwan in this period was a magnitude 6.7 event near Yilan, Taiwan on 27 December 2025, at a depth of 35 km. A magnitude 6.7 earthquake radiates roughly 169,203 tons of TNT equivalent in seismic energy.

Locations recording the most events include 花蓮縣 (2), 嘉義縣 (1).

94% of events here are shallow (under 70 km), 6% 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.

The deepest event on record here was a magnitude 4.4 earthquake at 274 km beneath Jiufen, Taiwan on 24 October 2025.

By band, the catalogue holds 4 in the magnitude 3 range, 106 in the magnitude 4 range, 24 in the magnitude 5 range, 4 in the magnitude 6 range.

The busiest single day was 27 January 2025, with 5 recorded events.

2 of these events carry a USGS link to NOAA tsunami information. That link flag does not mean a tsunami occurred or that a warning was issued.
