A very deep earthquake registered by the USGS as M6.0 earthquake hit the Autonomous Region of Bougainville, Papua New Guinea at 17:08 UTC on July 11. The agency is reporting a depth of 495.9 km (308.1 miles).
The epicenter was located 174 km (108.1 miles) N of Arawa, Papua New Guinea
There are some 50,000 people living within 100 km (62 miles).
Almost 200,000 people are estimated to have felt weak shaking.
However, no damage or casualties are expected given the depth of the quake.
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.
