Earthquakes in Papua New Guinea — December 2025
26 earthquakes were recorded in Papua New Guinea during December 2025, an average of 0.8 per day.
26 reached magnitude 4 or above and 8 reached magnitude 5 or above. The average focal depth was 93 km.
The month's largest event in Papua New Guinea was a magnitude 6.5 earthquake near Goroka, Papua New Guinea on 22 December 2025 at 10:31 UTC. A magnitude 6.5 earthquake radiates roughly 84,802 tons of TNT equivalent in seismic energy.
That is close to the Papua New Guinea monthly average of 26 events over the period we cover, and up from the 14 recorded the previous month.
58% of events here are shallow (under 70 km), 35% 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 18 in the magnitude 4 range, 7 in the magnitude 5 range, 1 in the magnitude 6 range.
Activity peaked on 26 December, when 3 events were recorded.
The month's largest events were M6.5 near Goroka, Papua New Guinea on 22 December at 110 km; M5.3 near Kokopo, Papua New Guinea on 21 December at 10 km; M5.3 near Panguna, Papua New Guinea on 10 December at 107 km.
