SYDNEY — Six bodies, including a child’s, were found in the sodden wreckage left by a tsunami that smashed into villages in the Solomon ­Islands, flattening dozens of homes in the South Pacific island chain.

The 4-foot, 11-inch waves that roared inland on Santa Cruz Island, in the eastern Solomons, on Wednesday were too fast to outrun for five elderly villagers and one child, who died after being sucked under the rushing water, George Herming, a spokesman for the prime minister, said Thursday. Several other people were still missing and dozens of strong aftershocks were keeping frightened villagers from returning to the coast, Herming said.
