Earthquakes in Indonesia — December 2024

45 earthquakes were recorded in Indonesia during December 2024, an average of 1.5 per day.

45 reached magnitude 4 or above and 8 reached magnitude 5 or above. The average focal depth was 107 km.

The month's largest event in Indonesia was a magnitude 5.5 earthquake near Amahai, Indonesia on 16 December 2024 at 10:14 UTC. A magnitude 5.5 earthquake radiates roughly 2,682 tons of TNT equivalent in seismic energy.

That is well above the Indonesia monthly average of 12 events over the period we cover — an unusually active month, and up from the 35 recorded the previous month.

51% of events here are shallow (under 70 km), 44% intermediate (70–300 km) and 4% 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 37 in the magnitude 4 range, 8 in the magnitude 5 range.

Activity peaked on 16 December, when 5 events were recorded.

The month's largest events were M5.5 near Amahai, Indonesia on 16 December at 26 km; M5.4 near Tual, Indonesia on 17 December at 111 km; M5.2 near Sarangani, Indonesia on 03 December at 12 km.

That is 260% above the 12 events Indonesia averages per month across the 2 months on record.

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