Earthquakes in Papua New Guinea, 1927–2026
From 1927 to October 19, 2026, USGS recorded 926 earthquakes of magnitude 6 or more in or off Papua New Guinea. 83 of them reached magnitude 7 or more; the strongest was a magnitude 8.1 on July 26, 1971 (1971 Bougainville Earthquake).
The last 30 days · as of
USGS recorded 31 earthquakes of magnitude 4.5 or more in the area the map frames in the last 30 days.
The latest: magnitude 4.9 on October 19 (52 km S of Kokopo, Papua New Guinea). The strongest: magnitude 6.2 on October 11 (79 km SSE of Panguna, Papua New Guinea).
What the record holds
The deadliest was not the strongest: a magnitude 7 on July 17, 1998 (50 km WNW of Aitape, Papua New Guinea), for which NOAA records 1,636 deaths. 86 earthquakes here in these years are on NOAA’s list of significant earthquakes. NOAA records deaths in 39 of the events here, 5,622 in all. The latest on NOAA’s list is a magnitude 6.9 on March 23, 2024 (36 km ENE of Ambunti, Papua New Guinea). NOAA lists 54 tsunamis that began in or off Papua New Guinea, and 6 from elsewhere that reached it with deaths or a metre of water or more. The highest water NOAA records here was 15.03 m, on July 17, 1998. The deadliest, on July 17, 1998, killed 2,205 people here by NOAA’s runup records. NOAA lists 23 significant eruptions of 10 volcanoes in or off Papua New Guinea. The largest was Lamington on January 21, 1951, at 4 on the volcanic explosivity index. It killed 2,942 people by NOAA’s count.

Good to know
- An event counts for Papua New Guinea when it began inside its borders, or at sea within 100 km of its coast (so one can count for two neighbours), or further out, up to 300 km, where Papua New Guinea is the nearest country.
- USGS counts here start at magnitude 6: the catalogue’s smaller quakes thin out going back, where few instruments listened.
- NOAA lists significant events only: earthquakes that killed, did about $1 million of damage, reached magnitude 7.5 or intensity X, or raised a tsunami, and eruptions and tsunamis by like measures. Magnitudes before 1900 are its estimates from written accounts.
- Deaths are NOAA’s total for each event, wherever people died, its tsunami and fires included. A tsunami counts the dead its runup records give for this place: NOAA’s total for a tsunami includes its source quake’s.
- A tsunami from elsewhere counts where one of its runups killed or rose a metre or more.
- The map frames the box around Papua New Guinea, its neighbours’ quakes included, so its count runs higher than this page’s.
- Counted to October 19, 2026, as is the map. The last 30 days ask USGS again.
