Significant 5.1 quake hits near Santo, Luganville, Sanma Province, Vanuatu

5.1 quake 27 Nov 12:59 pm (GMT +11)
5.1 quake 27 Nov 12:59 pm (GMT +11)
A magnitude 5.1 earthquake near Santo, Luganville, Sanma Province, Vanuatu, was reported only 25 minutes ago by the European-Mediterranean Seismological Centre (EMSC), considered one of the key international agencies that monitor seismic activity worldwide. The earthquake occurred at a shallow depth of 18 km beneath the epicenter around noon on Sunday, November 27th, 2022, at 12:59 pm 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 Geoscience Australia (GeoAu), which listed it as a magnitude 5.1 earthquake as well.
Based on the preliminary seismic data, the quake was probably felt by many people in the area of the epicenter. It should not have caused significant damage, other than objects falling from shelves, broken windows, etc.
In Norsup (pop. 3,000) located 28 km from the epicenter, and Santo (pop. 13,400) 40 km away, the quake should have been felt as light shaking.
Weak shaking might have been felt in Port-Olry (pop. 2,000) located 94 km from the epicenter.
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.
