A powerful earthquake, originally registered by the USGS as M6.8 but since downgraded to M6.6, struck near the coast of Vanuatu at 18:06 UTC on Jan 15. The agency is reporting a depth of 46.9 km (29.1 miles).
According to the USGS, the epicentre was located 105 km (65.2 miles) WNW of Sola (population 1,171) and 239.5 km (148.8 miles) NNW of Luganville (population 13,397), Vanuatu.
The Pacific Tsunami Warning Center reported the quake as an M6.8 — the centre advised “no action is required” as there’s no tsunami threat.
The Vanuatu archipelago in the South Pacific contains many active volcanoes including Ambae, Ambrym, Lopevi, and Yasur — the Stromboli counterpart of the Mediterranean.
Vanuatu’s island arc is the result of a north-south subduction zone stretching from the Matthew and Hunter islands in the south to Tinakula volcano in the Solomon Islands in the north.

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.
