Earthquakes in Taiwan — September 2026
6 earthquakes were recorded in Taiwan during September 2026, an average of 0.2 per day.
6 reached magnitude 4 or above and 0 reached magnitude 5 or above. The average focal depth was 20 km.
The month's largest event in Taiwan was a magnitude 4.6 earthquake near Hengchun, Taiwan on 13 September 2026 at 22:44 UTC. A magnitude 4.6 earthquake radiates roughly 120 tons of TNT equivalent in seismic energy.
That is close to the Taiwan monthly average of 6 events over the period we cover, and level with the 6 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 6 in the magnitude 4 range.
Activity peaked on 13 September, when 2 events were recorded.
The month's largest events were M4.6 near Hengchun, Taiwan on 13 September at 10 km; M4.6 near Hualien City, Taiwan on 28 September at 19 km; M4.5 near Donggang, Taiwan on 06 September at 33 km.
That is close to the 6 events Taiwan averages per month across the 23 months on record.
