On April 24, 2026 at 07:26 UTC, a magnitude 4.8 intermediate depth earthquake struck 113 km E of Kokopo, Papua New Guinea, at a depth of 119.8 km and coordinates -4.5392°, 153.2710°. This earthquake was detected by 32 seismic stations with good location accuracy and was assigned a USGS significance rating of 354, placing it among routine seismic activity.
This earthquake is part of an ongoing aftershock sequence following the magnitude 5.2 mainshock that occurred 19 days ago 155 km E of Kokopo, Papua New Guinea. Since the mainshock, the USGS has recorded 2 aftershocks in this area. Aftershock activity is expected to continue for days to weeks as stresses on surrounding faults redistribute.
The epicenter is located in Papua New Guinea, a region characterized by the collision and subduction of the Pacific, Australian, and Solomon Sea plates. View all earthquakes in Papua New Guinea.
