Magnitude & Depth:: A 6.9-magnitude earthquake occurred at a shallow depth of 10km.
Location:: The epicenter was near the southern coast of New Britain island, Papua New Guinea, approximately 121 miles southeast of Kimbe.
Time:: The quake struck at 6:04 am local time on Saturday.
Tsunami Warning:: The US Tsunami Warning Center issued a warning for potential tsunami waves of 1 to 3 meters (3 to 10 feet) along some coasts of Papua New Guinea. Waves less than 0.3 meters were forecast for the Solomon Islands.
Aftershock:: A smaller 5.3-magnitude aftershock occurred nearby about 30 minutes later.
Why this matters:: Shallow earthquakes near coastlines increase the risk of significant shaking and potential tsunamis, posing a direct threat to coastal populations and infrastructure.
The 6.9-magnitude earthquake originated in the Solomon Sea, a seismically active region. Its shallow depth (10km) contributed to the issuance of a tsunami warning by the US Tsunami Warning Center. While waves up to 3 meters were deemed possible for parts of the Papua New Guinea coast near the epicenter, the threat level for the Solomon Islands was lower. Authorities urged coastal populations in threatened areas to remain vigilant and follow instructions from local officials. The island of New Britain, home to over 500,000 people, felt the impact. A 5.3-magnitude aftershock followed shortly after the main quake, indicating ongoing seismic adjustments in the area. Importantly, the Bureau of Meteorology confirmed there was no tsunami threat to Australia.
What was the magnitude of the earthquake?
The earthquake had a magnitude of 6.9.
Where did the earthquake occur?
It struck off the southern coast of New Britain island, Papua New Guinea, in the Solomon Sea.
Was there a tsunami warning?
Yes, a tsunami warning was issued for potential waves of 1-3 meters along parts of the Papua New Guinea coast and smaller waves for the Solomon Islands.
Is Australia under threat?
No, the Bureau of Meteorology stated there is no tsunami threat to Australia from this event.
Who This Affects Most:: Coastal communities on New Britain island and potentially parts of the Solomon Islands are most directly affected by the quake and tsunami threat.
How to Prepare / Stay Safe:: If you are in a coastal area under a tsunami warning, stay alert for updates, heed instructions from national and local authorities, and be prepared to move to higher ground if instructed.
Key Insight:: This event highlights the significant seismic risks in the region and the importance of preparedness for earthquakes and potential tsunamis.
