Earthquakes in Papua New Guinea: Live Map & Ring of Fire Hazard

Papua New Guinea sits at one of the most tectonically complex and seismically active spots on Earth, where the Australian plate collides with the Pacific plate along with several smaller intervening plates — the Solomon Sea, Bismarck and Woodlark plates — that accommodate the intense convergence between the two giants. This patchwork of colliding and subducting plates makes PNG one of the world's most earthquake-prone countries, with dozens of moderate-to-strong quakes recorded every year and frequent volcanic activity to match.

On 17 July 1998, a magnitude 7.0 earthquake off the north coast near Aitape triggered a devastating local tsunami with waves over 10 metres high, killing more than 2,200 people in coastal villages — one of the deadliest tsunamis in Pacific history and a stark reminder of how quickly offshore ruptures here can turn deadly. More recently, the magnitude 7.5 Highlands earthquake of February 2018 struck the mountainous interior, killing over 100 people, triggering landslides that cut off remote communities, and damaging the Papua LNG gas facilities that are central to the national economy.

PNG's Geophysical Observatory, part of the country's Mineral Resources Authority, monitors seismic activity in cooperation with international networks, but much of the country's terrain is remote and mountainous, which historically has slowed disaster response after major quakes. Port Moresby, the capital, along with New Britain, Bougainville and the Highlands provinces, all sit within zones of significant seismic hazard. For a country where earthquakes are simply a fact of daily life, ongoing monitoring and community-level preparedness remain the main lines of defence.
