Magnitude 6.7 quake strikes off Solomons

A magnitude 6.7 quake has struck off the Solomon Islands at a depth of 44 kilometres but there's no threat of a tsunami.

An earthquake with a magnitude of 6.7 has struck off the Solomon Islands, according to the United States Geological Survey, the second powerful tremor in the islands to Australia's north in less than two weeks.

The Pacific Tsunami Warning Centre said Tuesday's quake, which was centred about 120km northwest of Kira Kira at a depth of 44km, had not triggered any tsunami threat.

It came less than two weeks after a powerful 7.8 earthquake struck off the Solomons, triggering a tsunami warning for a wide swathe of the South Pacific that sent hundreds of villagers rushing to higher ground.
