4.9 quake 24 Dec 4:54 pm (GMT +13)
4.9 quake 24 Dec 4:54 pm (GMT +13)
A shallow magnitude 4.9 earthquake was reported in the afternoon near Neiafu, Vava'u, Tonga.
According to the United States Geological Survey (USGS), the quake hit on Thursday 24 December 2020 at 4:54 pm local time at a shallow depth of 10 km. Shallow earthquakes are felt more strongly than deeper ones as they are closer to the surface. 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 4.9 as well.
Towns or cities near the epicenter where the quake might have been felt as very weak shaking include Neiafu (pop. 4,300) located 116 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.
