Moderate yet deep magnitude 5.9 quake hits 114 km north of Luganville, Vanuatu early morning

5.9 quake 5 Mar 3:53 am (GMT +11)
5.9 quake 5 Mar 3:53 am (GMT +11)
A magnitude 5.9 earthquake near Luganville, Sanma Province, Vanuatu, was reported only 13 minutes ago by the German Research Centre for Geosciences (GFZ), considered one of the key international agencies that monitor seismic activity worldwide. The earthquake occurred at an intermediate to considerable depth of 184 km beneath the epicenter early morning on Friday 5 March 2021 at 3:53 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.
Our monitoring service identified a second report from the European-Mediterranean Seismological Centre (EMSC) which listed the quake at magnitude 5.7.
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-Olry (pop. 2,000) located 64 km from the epicenter, and Luganville (pop. 13,400) 114 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.

Aore island, south of Luganville (121.6 km S of epicenter) [Map] / Light shaking (MMI IV) : We heard it coming, as usual. Seemed to take a while, but would have only been seconds, the shake arrived, nothing was knocked over but it was a long shake, the longest and strongest we have felt for a long time. | 7 users found this interesting.
