Magnitude 5.1 earthquake strikes near Port Vila, Shefa Province, Vanuatu
5.1 quake 15 Feb 6:43 am (GMT +11)
5.1 quake 15 Feb 6:43 am (GMT +11)
Vanuatu was shaken near Port Vila, Shefa Province, by an earthquake of magnitude 5.1 only 17 minutes ago, the German Research Centre for Geosciences (GFZ) reported.
The quake hit at an intermediate depth of 98 km beneath the epicenter near Port Vila, Shefa Province, Vanuatu, early morning on Monday 15 February 2021 at 6:43 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 the European-Mediterranean Seismological Centre (EMSC), which listed it as a magnitude 5.2 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 Port Vila (pop. 35,900) located 47 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.
