Earthquakes in Indonesia — March 2026

48 earthquakes were recorded in Indonesia during March 2026, an average of 1.5 per day.

48 reached magnitude 4 or above and 13 reached magnitude 5 or above. The average focal depth was 95 km.

The month's largest event in Indonesia was a magnitude 6.1 earthquake near Sinabang, Indonesia on 03 March 2026 at 04:56 UTC. A magnitude 6.1 earthquake radiates roughly 21,301 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 62 recorded the previous month.

65% of events here are shallow (under 70 km), 27% intermediate (70–300 km) and 8% 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 35 in the magnitude 4 range, 12 in the magnitude 5 range, 1 in the magnitude 6 range.

Activity peaked on 06 March, when 5 events were recorded.

The month's largest events were M6.1 near Sinabang, Indonesia on 03 March at 26 km; M5.7 near Abepura, Indonesia on 26 March at 54 km; M5.4 near Tobelo, Indonesia on 06 March at 10 km.

That is 32% below the 70 events Indonesia averages per month across the 21 months on record.
