Earthquakes in Indonesia — May 2026

47 earthquakes were recorded in Indonesia during May 2026, an average of 1.5 per day.

47 reached magnitude 4 or above and 10 reached magnitude 5 or above. The average focal depth was 76 km.

The month's largest event in Indonesia was a magnitude 6.2 earthquake near Tual, Indonesia on 14 May 2026 at 17:53 UTC. A magnitude 6.2 earthquake radiates roughly 30,089 tons of TNT equivalent in seismic energy.

That is below the Indonesia monthly average of 70 events over the period we cover — a comparatively quiet month, and down from the 126 recorded the previous month.

66% of events here are shallow (under 70 km), 28% intermediate (70–300 km) and 6% 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 37 in the magnitude 4 range, 9 in the magnitude 5 range, 1 in the magnitude 6 range.

Activity peaked on 29 May, when 5 events were recorded.

The month's largest events were M6.2 near Tual, Indonesia on 14 May at 146 km; M5.8 near Bitung, Indonesia on 22 May at 48 km; M5.8 near Tambolaka, Indonesia on 05 May at 36 km.

That is 33% below the 70 events Indonesia averages per month across the 21 months on record.
