Magnitude 6.4 earthquake rattles Papua New Guinea in latest Pacific Ring of Fire activity
The USGS issued a Green alert, saying the quake has a low likelihood of casualties and damage.
- On Sunday, September 20, 2026, a magnitude 6.4 earthquake struck the Eastern New Guinea region of Papua New Guinea, with the U.S. Geological Survey reporting the epicenter approximately 30 miles from Kainantu.
- The earthquake occurred on the Australia-Pacific plate boundary, a 2,500-mile-long region along the Pacific Ring of Fire that contains roughly 452 volcanoes and generates 90% of the world's earthquakes.
- Striking at a depth of about 64 miles, the quake caused moderate shaking felt by 386,000 people across the region. The USGS issued a Green alert for shaking-related fatalities and economic losses.
- Authorities confirmed there is no tsunami threat from this seismic event, and the agency reports a low likelihood of casualties and damage given limited liquefaction extent.
- Papua New Guinea remains highly active seismically, with 13 magnitude 7.5 or greater earthquakes recorded since 1900. Recent activity in this region has occasionally caused secondary hazards such as landslides and liquefaction.
