A strong 6.9-magnitude earthquake struck beneath the sea near the south Pacific island nation of Vanuatu, but no tsunami warning was issued, the US Geological Survey (USGS) said Sunday.
There were no immediate reports of damage from the quake, which hit at 9:03pm (1003 GMT) at a depth of 31.1 kilometres (19.3 miles), 110 kilometres from the town of Isangel on Tanna island, the USGS said.
The quake was the latest in a series of undersea tremors near the island, which is home to an active volcano.
