The month's largest event in Papua New Guinea was a magnitude 5.4 earthquake near Bulolo, Papua New Guinea on 02 September 2026 at 20:04 UTC. A magnitude 5.4 earthquake radiates roughly 1,898 tons of TNT equivalent in seismic energy.
That is below the Papua New Guinea monthly average of 25 events over the period we cover — a comparatively quiet month, and down from the 21 recorded the previous month.
100% of events here are shallow (under 70 km), 0% intermediate (70–300 km) and 0% 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 1 in the magnitude 5 range.
That is 96% below the 25 events Papua New Guinea averages per month across the 22 months on record.
