A shallow 6.6-magnitude quake hit off the Solomon Islands on Saturday, the United States Geological Survey said, but there was no Pacific-wide tsunami expected.

The quake struck some 214 kilometres (132 miles) west of the town of Lata but 460 kilometres from the capital Honiara, USGS said.

"Based on all the available data a destructive Pacific-wide tsunami is not expected," the Pacific Tsunami Warning Centre said in an advisory.
