Significant earthquake of magnitude 5.0 just reported 75 km northwest of Te Anau, New Zealand
5.0 quake 22 Jan 2:51 am (GMT +13)
5.0 quake 22 Jan 2:51 am (GMT +13)
New Zealand was shaken near Te Anau, Southland District, Southland, by an earthquake of magnitude 5.0 only 9 minutes ago, New Zealand's Earthquake Commission and Geological Survey (GeoNet) reported.
The quake hit at a shallow depth of 18 km beneath the epicenter near Te Anau, Southland District, Southland, New Zealand, early morning on Friday 22 January 2021 at 2:51 am 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.
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 Te Anau (pop. 2,100) located 75 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.
