The United States Geological Survey reported a magnitude 4.7 quake in Vanuatu near Santo, Luganville, Sanma Province, only 25 minutes ago. The earthquake hit in the morning on Thursday, December 23rd, 2021, at 11:47 am local time at an intermediate depth of 111.7 km. 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 4.7 earthquake as well.
Towns or cities near the epicenter where the quake might have been felt as very weak shaking include Port-Olry (pop. 2,000) located 28 km from the epicenter, and Santo (pop. 13,400) 62 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.
