A deep earthquake registered by the USGS as M6.2 hit the Solomon Islands at 03:51 UTC on Jan 26. The agency is reporting a depth of 357.8 km (222 miles).
There are approximately 62,000 people living within 100 km.
More than 1,100,000 people are estimated to have felt weak shaking.
The quake was too deep to produce a tsunami.
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, and the increase in Galactic Cosmic Rays penetrating silica-rich magma.
