M4.3 Earthquake 78 km SSE of Panguna, Papua New Guinea — April 30, 2024
2024-04-30 19:00:44 UTC (2024-04-30) · approx. 5:00 AM UTC+10 local
On April 30, 2024 at 19:00 UTC, a magnitude 4.3 shallow crustal earthquake struck 78 km SSE of Panguna, Papua New Guinea, at a depth of 65.5 km and coordinates -6.9171°, 155.8659°.
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 6.2 mainshock that occurred 1 day ago 79 km SSE of Panguna, Papua New Guinea. Since the mainshock, the USGS has recorded 0 aftershocks in this area. Aftershock activity is expected to continue for weeks to months 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 78 km SSE of Panguna, Papua New Guinea on April 30, 2024 at 19:00 UTC had a depth of 65.5 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 M6.2 one earlier?
No. This magnitude 4.3 earthquake is an aftershock of the larger magnitude 6.2 mainshock that occurred earlier 79 km SSE of Panguna, Papua New Guinea. Aftershocks are smaller earthquakes triggered by stress changes from the mainshock.
