Aftershock of the M5.2 mainshock.
On April 24, 2026 at 23:59 UTC, a magnitude 4.6 intermediate depth earthquake struck 151 km ESE of Kokopo, Papua New Guinea, at a depth of 115.3 km and coordinates -4.6304°, 153.6037°. This earthquake was detected by 44 seismic stations with good location accuracy and was assigned a USGS significance rating of 326, placing it among routine seismic activity.
This earthquake is part of an ongoing aftershock sequence following the magnitude 5.2 mainshock that occurred 20 days ago 155 km E of Kokopo, Papua New Guinea. Since the mainshock, the USGS has recorded 3 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.

Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 4.6 earthquakes can continue for several days and gradually diminish over time.
Is this the same earthquake as the M5.2 one earlier?
No. This magnitude 4.6 earthquake is an aftershock of the larger magnitude 5.2 mainshock that occurred earlier 155 km E of Kokopo, Papua New Guinea. Aftershocks are smaller earthquakes triggered by stress changes from the mainshock.
Has Papua New Guinea had earthquakes this big before?
The largest recorded earthquake in Papua New Guinea was the M8.0 New Britain earthquake of July 18, 1971. Today's magnitude 4.6 event is significantly smaller than that historical record.
