Earthquakes in Japan — July 2026

60 earthquakes were recorded in Japan during July 2026, an average of 1.9 per day.

60 reached magnitude 4 or above and 14 reached magnitude 5 or above. The average focal depth was 84 km.

The month's largest event in Japan was a magnitude 7.1 earthquake near Uki, Japan on 28 July 2026 at 07:28 UTC. A magnitude 7.1 earthquake radiates roughly 673,610 tons of TNT equivalent in seismic energy.

That is close to the Japan monthly average of 57 events over the period we cover, and down from the 61 recorded the previous month.

78% of events here are shallow (under 70 km), 8% intermediate (70–300 km) and 13% deep-focus (over 300 km). That proportion of deep-focus events is the signature of a subduction zone: only a cold slab descending into the mantle stays brittle enough to rupture at those depths.

By band, the catalogue holds 46 in the magnitude 4 range, 9 in the magnitude 5 range, 3 in the magnitude 6 range, 2 in the magnitude 7 range.

Activity peaked on 28 July, when 9 events were recorded.

The month's largest events were M7.1 near Uki, Japan on 28 July at 10 km; M7.1 near Uki, Japan on 28 July at 10 km; M6.8 near Uto, Japan on 28 July at 10 km.

That is close to the 57 events Japan averages per month across the 21 months on record.
