M4.3 Earthquake 208 km WNW of Panguna, Papua New Guinea — June 6, 2024
2024-06-06 17:04:11 UTC (2024-06-06) · approx. 3:04 AM UTC+10 local
On June 6, 2024 at 17:04 UTC, a magnitude 4.3 shallow crustal earthquake struck 208 km WNW of Panguna, Papua New Guinea, at a depth of 43.6 km and coordinates -5.4942°, 153.7867°.
Physical scale: An earthquake of magnitude 4.3 releases seismic energy equivalent to roughly 43 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 558 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 5.3 mainshock that occurred 14 days ago 217 km SE 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.

Common Questions
How strong was the magnitude 4.3 earthquake near Panguna, Papua New Guinea?
The magnitude 4.3 earthquake that struck 208 km WNW of Panguna, Papua New Guinea on June 6, 2024 at 17:04 UTC had a depth of 43.6 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 4.3 earthquakes can continue for several days and gradually diminish over time.
Is this the same earthquake as the M5.3 one earlier?
No. This magnitude 4.3 earthquake is an aftershock of the larger magnitude 5.3 mainshock that occurred earlier 217 km SE of Kokopo, Papua New Guinea. Aftershocks are smaller earthquakes triggered by stress changes from the mainshock.
