A shallow and powerful earthquake registered by the USGS as M6.2 struck New Britain, Papua New Guinea at 08:21 UTC on July 15. The agency is reporting a depth of 59 km (36 miles).
The epicenter was located 25 km (15 miles) N of Kandrian, Papua New Guinea.
Some 205,000 people are estimated to have felt the shaking.
Although there is a low likelihood of casualties and damage given the remote location 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.
