Magnitude 5.6 earthquake strikes near Agrihan Village, Agrihan Island, Northern Islands, Northern Mariana Islands

5.6 quake 26 Nov 4:05 pm (GMT +10)
5.6 quake 26 Nov 4:05 pm (GMT +10)
Northern Mariana Islands was shaken near Agrihan Village, Agrihan Island, Northern Islands, by an earthquake of magnitude 5.6 only 24 minutes ago, the United States Geological Survey reported.
The quake hit at a shallow depth of 18.1 km beneath the epicenter near Agrihan Village, Agrihan Island, Northern Islands, Northern Mariana Islands, in the afternoon on Saturday, November 26th, 2022, at 4:05 pm local time. 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 Italy's National Institute of Geophysics and Volcanology (INGV) which listed the quake at magnitude 5.8. Other agencies reporting the same quake include The Incorporated Research Institutions for Seismology (IRIS) at magnitude 5.6, the German Research Centre for Geosciences (GFZ) at magnitude 5.5, France's Réseau National de Surveillance Sismique (RéNaSS) at magnitude 5.4, the citizen-seismograph network of RaspberryShake at magnitude 5.6, and the European-Mediterranean Seismological Centre (EMSC) at magnitude 5.6.
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.
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 Agrihan Village (pop. 20) located 138 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.
