Significant 5.2 quake hits near Neiafu, Tonga
5.2 quake 6 Dec 7:41 pm (GMT +13)
5.2 quake 6 Dec 7:41 pm (GMT +13)
The United States Geological Survey (USGS) reported a magnitude 5.2 quake in Tonga near Neiafu, Vava'u, only 22 minutes ago. The earthquake hit early evening on Sunday 6 December 2020 at 7.41 pm local time at a shallow depth of 10 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 Geoscience Australia (GeoAu), which listed it as a magnitude 5.1 earthquake. A third agency, the European-Mediterranean Seismological Centre (EMSC), reported the same quake at magnitude 5.2.
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 Neiafu (pop. 4,300) located 129 km from the epicenter.
