Moderate yet deep magnitude 5.0 earthquake 47 km northwest of Neiafu, Tonga

A magnitude 5.0 earthquake near Neiafu, Vava'u, Tonga, was reported only 22 minutes ago by the United States Geological Survey, considered one of the key international agencies that monitor seismic activity worldwide. The earthquake occurred at an intermediate depth of 137.9 km beneath the epicenter early morning on Wednesday, November 30th, 2022, at 1:58 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 Geoscience Australia (GeoAu) which listed the quake at magnitude 5.1. Other agencies reporting the same quake include the citizen-seismograph network of RaspberryShake at magnitude 5.0, and the European-Mediterranean Seismological Centre (EMSC) at magnitude 5.0.
Generally quakes of this magnitude are recorded by more than one agency and the results can vary, with subsequent reports that come in after the first one often showing more accuracy.
Towns or cities near the epicenter where the quake might have been felt as very weak shaking include Neiafu (pop. 4,300) 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.
