Earthquakes in Indonesia — August 2026

163 earthquakes were recorded in Indonesia during August 2026, an average of 5.3 per day.

163 reached magnitude 4 or above and 52 reached magnitude 5 or above. The average focal depth was 34 km.

The month's largest event in Indonesia was a magnitude 7.7 earthquake near Ende, Indonesia on 14 August 2026 at 21:58 UTC. A magnitude 7.7 earthquake radiates roughly 5.4 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 70 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 111 in the magnitude 4 range, 49 in the magnitude 5 range, 2 in the magnitude 6 range, 1 in the magnitude 7 range.

Activity peaked on 15 August, when 34 events were recorded.

The month's largest events were M7.7 near Ende, Indonesia on 14 August at 10 km; M6.9 near Pematangsiantar, Indonesia on 15 August at 173 km; M6.1 near Ende, Indonesia on 14 August at 10 km.

That is 133% above the 70 events Indonesia averages per month across the 21 months on record.
