Earthquakes in Indonesia — April 2026

124 earthquakes were recorded in Indonesia during April 2026, an average of 4.1 per day.

124 reached magnitude 4 or above and 44 reached magnitude 5 or above. The average focal depth was 58 km.

The month's largest event in Indonesia was a magnitude 7.8 earthquake near Ternate, Indonesia on 01 April 2026 at 22:48 UTC. A magnitude 7.8 earthquake radiates roughly 7.6 million tons of TNT equivalent in seismic energy.

That is well above the Indonesia monthly average of 70 events over the period we cover — an unusually active month, and up from the 48 recorded the previous month.

87% of events here are shallow (under 70 km), 10% intermediate (70–300 km) and 3% deep-focus (over 300 km). The mix is dominated by shallow crustal events, with a minority of intermediate-depth activity.

By band, the catalogue holds 80 in the magnitude 4 range, 41 in the magnitude 5 range, 1 in the magnitude 6 range, 2 in the magnitude 7 range.

Activity peaked on 02 April, when 40 events were recorded.

The month's largest events were M7.8 near Ternate, Indonesia on 01 April at 10 km; M7.4 near Ternate, Indonesia on 01 April at 35 km; M6.2 near Ternate, Indonesia on 02 April at 35 km.

That is 77% above the 70 events Indonesia averages per month across the 21 months on record.

This month also holds the strongest earthquake recorded in Indonesia in our entire catalogue.
