Significant 5.2 quake hits near Port Moresby, National Capital, Papua New Guinea
5.2 quake 28 Nov 6:36 am (GMT +10)
5.2 quake 28 Nov 6:36 am (GMT +10)
An earthquake of magnitude 5.2 occurred early morning on Sunday, November 28th, 2021, at 6:36 am local time near Port Moresby, National Capital, 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.
A second report was later issued by France's Réseau National de Surveillance Sismique (RéNaSS), which listed it as a magnitude 5.2 earthquake as well. Other agencies reporting the same quake include the European-Mediterranean Seismological Centre (EMSC) at magnitude 5.3, and Indonesia's Meteorology, Climatology, and Geophysical Agency at magnitude 5.1.
Generally quakes of this magnitude are recorded by more than one agency and the results can vary, with subsequent reports that come in after the first one often showing more accuracy.
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 Kokoda (pop. 6,200) located 56 km from the epicenter, Popondetta (pop. 28,200) 62 km away, and Port Moresby (pop. 283,700) 99 km away.
