A strong and shallow earthquake registered by the USGS as M6.1 hit near the coast of Papua New Guinea at 12:48 UTC March 10, 2019. The agency is reporting a depth of 10 km (6.2 miles).
The epicentre was located 140km SSW of Kulumadau, 161 km ENE of Samarai and 176 km E of Alotau, Papua New Guinea.
68,000 people are estimated to have felt light shaking and 71,000 weak.
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 increase in Galactic Cosmic Rays penetrating silica-rich magma.
