A powerful earthquake registered by the USGS as M6.0 hit near New Britain, Papua New Guinea at 22:37 UTC on May 17. The agency is reporting a depth of 21.9 km (13.6 miles).
The epicenter was located 12km (7.5 miles) SSW of Taron, Papua New Guinea.
There are some 150,000 people living within 100 km (62 miles), though only 2,500 are estimated to have felt strong shaking.
No damage or casualties have been reported.
And no tsunami warnings were issued.
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.
