The waves proved deadly for five elderly villagers and a child, who weren't fast enough to outrun the rushing water, said George Herming, a spokesman for the prime minister. Three more bodies were found Thursday, but Herming said details of how those victims died were not immediately available.
Several others are missing and dozens of strong aftershocks were keeping frightened villagers from returning to the coast, Herming said.
"People are still scared of going back to their homes because there's nothing left, so they are residing in temporary shelters on higher ground," Herming said.
The tsunami was generated by an 8.0-magnitude earthquake that struck near the town of Lata, on Santa Cruz in Temotu, the easternmost province in the Solomons.
Disaster officials were en route to the isolated area Thursday after the local airport, which was flooded by the tsunami, was finally cleared of debris.
Another jolt that registered a magnitude of 6.6 hit near Santa Cruz at 5:59 a.m. Friday, according to the U.S. Geological Survey. No tsunami alert was issued. There were no immediate reports of further damage or casualties.
Prime Minister Gordon Darcy Lilo was on a plane to Santa Cruz to assess damage Friday morning when the aftershock hit, said Silas Lilo, a spokesman for the Prime Minister's office. The plane was forced to return to the capital Honiara.
The Solomons comprise more than 200 islands with a population of about 552,000 people. They lie on the "Ring of Fire" — an arc of earthquake and volcanic zones that stretches around the Pacific Rim and where about 90 percent of the world's quakes occur.
More than 50 people were killed and thousands lost their homes in April 2007 when a magnitude-8.1 quake hit the western Solomon Islands, sending waves crashing into coastal villages.
