A deep and powerful earthquake (registered by the USGS as M6.7) hit between Fiji/Tonga at 15:54 UTC on September 01. The agency is reporting a depth of 604.1 km (375 miles).
The epicenter was located 34 km (21 miles) NNE of Ndoi Island, Fiji.
And, according to PTWC, no tsunami warnings have been issued.
A M4.6 aftershock struck soon after the big M6.7, at 17:18 UTC, again at a depth of 600-or-so km — also visible in the featured image (above).
No damage or casualties have been reported, nor are they expected given the depth and remote locations of the quakes.
Seismic and Volcanic activity has been correlated to changes in our sun.
The recent global uptick in earthquakes and volcanic eruptions is likely attributed to the drop-off in solar activity, coronal holes, a waning magnetosphere, and the influx of Cosmic Rays penetrating silica-rich magma.
