The quake hit at a depth of 19 kilometres (11 miles), 184 kilometres from Lata and 487 kilometres from the capital Honiara. It was followed a smaller 4.9-magnitude aftershock.

"Based on all available data there is no tsunami threat from this earthquake," the Pacific Tsunami Warning Centre said.

The Solomons are part of the "Ring of Fire", a zone of tectonic activity around the Pacific that is subject to frequent earthquakes and volcanic eruptions.

Earlier this month, neighbouring Papua New Guinea was rattled by a 7.1 quake but there were no reports of major damage.

In 2013, the Solomons were hit by a tsunami after an 8.0-magnitude quake, leaving at least 10 people dead and thousands homeless after buildings were destroyed.
