Magnitude 5.4 earthquake strikes near Arawa, Bougainville, Papua New Guinea
Earthquake 5.4 October 2 1:17 p.m. (GMT +11)
A second report was later released by the Indonesian Meteorological, Climatological and Geophysical Agency, which also listed it as a magnitude 5.4 earthquake. Other agencies reporting the same earthquake include the Euro-Mediterranean Seismological Center (EMSC) at magnitude 5.1 and France’s National Seismic Monitoring Network (RéNaSS) at magnitude 5.2.
Based on preliminary seismic data, the quake should not have caused significant damage, but was likely felt by many as a slight vibration in the epicenter area.
Weak tremors could have been felt in Buin (750 inhabitants) located 105 km from the epicenter, Panguna (2,900 inhabitants) at 113 km, Arawa (40,300 inhabitants) at 126 km and Kieta (3,600 inhabitants) at 132 km.
