Earthquakes in Indonesia — December 2025
59 earthquakes were recorded in Indonesia during December 2025, an average of 1.9 per day.
59 reached magnitude 4 or above and 13 reached magnitude 5 or above. The average focal depth was 81 km.
The month's largest event in Indonesia was a magnitude 5.6 earthquake near Bengkulu, Indonesia on 27 December 2025 at 00:22 UTC. A magnitude 5.6 earthquake radiates roughly 3,788 tons of TNT equivalent in seismic energy.
That is close to the Indonesia monthly average of 70 events over the period we cover, and up from the 52 recorded the previous month.
64% of events here are shallow (under 70 km), 34% intermediate (70–300 km) and 2% deep-focus (over 300 km). A substantial share of intermediate-depth events points to a subducting slab beneath the region rather than purely crustal faulting.
By band, the catalogue holds 46 in the magnitude 4 range, 13 in the magnitude 5 range.
Activity peaked on 14 December, when 4 events were recorded.
The month's largest events were M5.6 near Bitung, Indonesia on 21 December at 55 km; M5.6 near Bengkulu, Indonesia on 27 December at 10 km; M5.2 near Sinabang, Indonesia on 09 December at 10 km.
That is 16% below the 70 events Indonesia averages per month across the 21 months on record.
