Earthquakes in Japan — November 2025

96 earthquakes were recorded in Japan during November 2025, an average of 3.2 per day.

96 reached magnitude 4 or above and 32 reached magnitude 5 or above. The average focal depth was 38 km.

The month's largest event in Japan was a magnitude 6.8 earthquake near Yamada, Japan on 09 November 2025 at 08:03 UTC. A magnitude 6.8 earthquake radiates roughly 239,006 tons of TNT equivalent in seismic energy.

That is well above the Japan monthly average of 57 events over the period we cover — an unusually active month, and up from the 35 recorded the previous month.

91% of events here are shallow (under 70 km), 7% intermediate (70–300 km) and 2% 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 64 in the magnitude 4 range, 29 in the magnitude 5 range, 3 in the magnitude 6 range.

Activity peaked on 09 November, when 29 events were recorded.

1 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 M6.8 near Yamada, Japan on 09 November at 10 km; M6.4 near Yamada, Japan on 09 November at 10 km; M6.0 near Yamada, Japan on 10 November at 11 km.

That is 69% above the 57 events Japan averages per month across the 21 months on record.
