Earthquake Report comment :
A rather deep (51 km) earthquake occurred in the Solomon Sea at a reasonable distance from the Bougainville Island coast.
Papua New Guinea has almost daily earthquakes and this one has only a limited chance on damage and injuries.
The main danger of these earthquakes are local, sometimes devastating tsunamis, triggered bu undersea landslides.
A good look on the satllite Google map will reveal an epicenter just on the steep ridge where one of the 2 plates is subducting the other.
This earthquake happened in the middle of the night (4 AM).
On the positive side, GDACS has issued a GREEN earthquake report.
NOAA has NOT issued a tsunami report nor GDACS

Bougainville island is part of the Pacific Ring of Fire.
The Pacific Ring of Fire (or sometimes just the Ring of Fire) is an area where large numbers of earthquakes and volcanic eruptions occur in the basin of the Pacific Ocean. In a 40,000 km (25,000 mi) horseshoe shape, it is associated with a nearly continuous series of oceanic trenches, volcanic arcs, and volcanic belts and/or plate movements. The Ring of Fire has 452 volcanoes and is home to over 75% of the world’s active and dormant volcanoes.
