Significant magnitude 5.1 earthquake 97 km west of Arawa, Papua New Guinea

5.1 quake 27 Nov 2:45 pm (GMT +11)
5.1 quake 27 Nov 2:45 pm (GMT +11)
An earthquake of magnitude 5.1 occurred early afternoon on Saturday, November 27th, 2021, at 2:45 pm local time near Arawa, Bougainville, Papua New Guinea, as reported by the German Research Centre for Geosciences (GFZ).
According to preliminary data, the quake was located at a shallow depth of 10 km. Shallow earthquakes are felt more strongly than deeper ones as they are closer to the surface. 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.
Our monitoring service identified a second report from France's Réseau National de Surveillance Sismique (RéNaSS) which listed the quake at magnitude 5.2. A third agency, the European-Mediterranean Seismological Centre (EMSC), reported the same quake at magnitude 5.5.
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 Panguna (pop. 2,900) located 88 km from the epicenter, Arawa (pop. 40,300) 97 km away, Kieta (pop. 3,600) 104 km away, and Buin (pop. 750) 125 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.
