Magnitude 5.4 earthquake strikes near Arawa, Bougainville, Papua New Guinea

5.4 quake 28 Nov 5:48 am (GMT +11)
5.4 quake 28 Nov 5:48 am (GMT +11)
The United States Geological Survey reported a magnitude 5.4 quake in Papua New Guinea near Arawa, Bougainville, only 21 minutes ago. The earthquake hit early morning on Sunday, November 28th, 2021, at 5:48 am local time at a moderately shallow depth of 67.9 km. The exact magnitude, epicenter, and depth of the quake might be revised within the next few hours or minutes as seismologists review data and refine their calculations, or as other agencies issue their report.
A second report was later issued by France's Réseau National de Surveillance Sismique (RéNaSS), which listed it as a magnitude 5.6 earthquake. Other agencies reporting the same quake include the European-Mediterranean Seismological Centre (EMSC) at magnitude 5.4, and the German Research Centre for Geosciences (GFZ) at magnitude 5.3.
Based on the preliminary seismic data, the quake should not have caused any significant damage, but was probably felt by many people as light vibration in the area of the epicenter.
Weak shaking might have been felt in Buin (pop. 750) located 40 km from the epicenter, Panguna (pop. 2,900) 92 km away, Kieta (pop. 3,600) 95 km away, and Arawa (pop. 40,300) 96 km away.
VolcanoDiscovery will automatically update magnitude and depth if these change and follow up if other significant news about the quake become available. If you're in the area, please send us your experience through our reporting mechanism, either online or via our mobile app. This will help us provide more first-hand updates to anyone around the globe who wants to know more about this quake.
