A powerful magnitude 8.0 earthquake off the Solomon Islands generated a tsunami of up to 5 feet that killed at least 5 people, a hospital official says, while the death toll is feared to rise as officials inspect dozens of damaged homes.

Authorities on Wednesday canceled warnings for tsunamis on more distant coasts.

Solomons officials reported two 1.5-meter (4 foot, 11 inch) waves hit the western side of Santa Cruz Island, damaging between 70 and 80 homes and properties, said George Herming, a spokesman for the prime minister. Many villagers of the South Pacific island chain had headed to higher ground as a precaution, Herming said. Dozens of aftershocks stronger than magnitude 5 followed the quake

Augustine Pilve, who is Lata hospital's director of nursing, told a New Zealand television station that five were killed, including a boy around 10 years old, Reuters reports.

Solomon Islands Police Commissioner John Lansley earlier said local police patrols had reported that several people were presumed dead, though the reports were still being verified.

"Sadly, we believe some people have lost their lives," he said. "At the moment we potentially know of four, but there may of course be more."

One of the people presumed dead was fishing in a dugout canoe when the first wave hit, sweeping him out to sea, Herming said. Officials were searching for his body. Another woman was believed to have drowned when the water rushed into her village, Herming said.

Four villages on Santa Cruz were impacted by the waves, with two facing severe damage, Lansley said. Other areas of the Solomons did not appear to have been seriously affected.

Disaster officials were struggling to reach the remote area after the tsunami flooded the airstrip at the nearest airport and left it littered with debris.

The tsunami formed after a magnitude-8.0 earthquake struck near the town of Lata, on Santa Cruz in Temotu, the easternmost province in the Solomons, about a 3-hour flight from the capital, Honiara. Temotu has a population of around 30,000.
