Magnitude 5.9 earthquake strikes near Norsup, Malampa Province, Vanuatu
5.9 quake 10 Jan 5:48 pm (GMT +11)
5.9 quake 10 Jan 5:48 pm (GMT +11)
A intermediate to deep magnitude 5.9 earthquake was reported in the afternoon near Norsup, Malampa Province, Vanuatu.
According to the German Research Centre for Geosciences (GFZ), the quake hit on Sunday 10 January 2021 at 5:48 pm local time at an intermediate to considerable depth of 162 km. The strength of the earthquake may have been tempered by its relative great depth below the surface, which makes it feel weaker in absolute terms. 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 the European-Mediterranean Seismological Centre (EMSC), which listed it as a magnitude 5.7 earthquake.
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 Lakatoro (pop. 710) located 37 km from the epicenter, Norsup (pop. 3,000) 39 km away, and Luganville (pop. 13,400) 89 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.
