A strong earthquake has struck under the sea near the Pacific Island nation of Vanuatu. There are no reports of damage or injuries and officials say there is no significant tsunami threat.
The US Geological Survey says the quake measured magnitude 6.6 and was centred 107km northwest of the remote island of Isangel at a depth of 17km.
The Pacific Tsunami Warning Centre says there is no threat of a widespread tsunami.
Vanuatu is part of the Pacific "Ring of Fire" - an arc of earthquake and volcanic zones stretching from South America through Alaska and down through the South Pacific.
A 7.3-magnitude quake struck near Vanuatu the day after Christmas, causing a tsunami a few inches high but no damage.
