5.1 quake 17 Aug 3:35 am (GMT +11)
A magnitude 5.1 earthquake near Luganville, Sanma Province, Vanuatu, was reported only 16 minutes ago by the German Research Centre for Geosciences (GFZ), considered one of the key international agencies that monitor seismic activity worldwide. The earthquake occurred at an intermediate to considerable depth of 172 km beneath the epicenter early morning on Tuesday 17 August 2021 at 3:35 am local time. 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 5.1 earthquake as well. A third agency, the European-Mediterranean Seismological Centre (EMSC), reported the same quake at magnitude 5.1.
Towns or cities near the epicenter where the quake might have been felt as very weak shaking include Lakatoro (pop. 710) located 45 km from the epicenter, Norsup (pop. 3,000) 47 km away, and Luganville (pop. 13,400) 91 km away.
VolcanoDiscovery will automatically update magnitude and depth if these change and follow up if other significant news about the quake become available.
