4.5 quake 1 Nov 2:35 am (GMT +11)
4.5 quake 1 Nov 2:35 am (GMT +11)
The United States Geological Survey reported a magnitude 4.5 quake in Vanuatu near Santo, Luganville, Sanma Province, 33 minutes ago. The earthquake hit early morning on Monday, November 1st, 2021, at 2:35 am local time at a moderately shallow depth of 37.4 km. Magnitude and other quake parameters can still change in the coming hours as the agency continues to process seismic data.
Our monitoring service identified a second report from the European-Mediterranean Seismological Centre (EMSC) which listed the quake at magnitude 4.5 as well.
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 Santo (pop. 13,400) located 45 km from the epicenter, and Port-Olry (pop. 2,000) 50 km away.
Other towns or cities near the epicenter where the quake might have been felt as very weak shaking include Norsup (pop. 3,000) located 90 km from the epicenter, and Lakatoro (pop. 710) 94 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.
