An earthquake of magnitude 4.6 occurred only 30 minutes ago 53 km northwest of Te Anau, New Zealand, New Zealand's Earthquake Commission and Geological Survey (GeoNet) reported.
The quake hit at an intermediate depth of 78.8 km beneath the epicenter near Te Anau, Southland District, Southland, New Zealand, around noon on Friday, March 17th, 2023, at 1:00 pm 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 the European-Mediterranean Seismological Centre (EMSC) which listed the quake at magnitude 4.6 as well. A third agency, the citizen-seismograph network of RaspberryShake, reported the same quake at magnitude 4.6.
