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

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.
