M4.4 Earthquake 62 km E of Kokopo, Papua New Guinea — March 24, 2024
2024-03-24 15:24:15 UTC (2024-03-24) · approx. 1:24 AM UTC+10 local
On March 24, 2024 at 15:24 UTC, a magnitude 4.4 intermediate depth earthquake struck 62 km E of Kokopo, Papua New Guinea, at a depth of 80.4 km and coordinates -4.3790°, 152.8351°.
Physical scale: An earthquake of magnitude 4.4 releases seismic energy equivalent to roughly 60 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 655 m — a useful intuition for the size of the slip patch on the fault.
This earthquake is part of an ongoing aftershock sequence following the magnitude 5.6 mainshock that occurred 16 days ago 72 km ESE 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.

Common Questions
How strong was the magnitude 4.4 earthquake near Kokopo, Papua New Guinea?
The magnitude 4.4 earthquake that struck 62 km E of Kokopo, Papua New Guinea on March 24, 2024 at 15:24 UTC had a depth of 80.4 km. For context, this was a light earthquake commonly felt near the epicenter.
Were there aftershocks?
Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 4.4 earthquakes can continue for several days and gradually diminish over time.
Is this the same earthquake as the M5.6 one earlier?
No. This magnitude 4.4 earthquake is an aftershock of the larger magnitude 5.6 mainshock that occurred earlier 72 km ESE of Kokopo, Papua New Guinea. Aftershocks are smaller earthquakes triggered by stress changes from the mainshock.
