AT least three people are reported dead today after a tsunami hit the Solomon Islands following a powerful earthquake, casing a major alert across the region.
The quake has fuelled fears of a repeat of the 2004 disaster. The good news for Australia, however, is that experts say the threat to the nation's north has now eased.
The tsunami followed after a powerful earthquake with a magnitude of up to 8.1 struck in the New Georgia Islands region, which had prompted the Pacific Tsunami Warning Centre to issue a tsunami warning.
The Japanese public broadcaster NHK, quoting a local official in the affected area, said some villages had every home destroyed.
"I think it was more than five metres (high). They found three people dead in different locations," the official said.
Solomons police spokesman Mick Spinks said there had been sketchy reports of damage caused by a tsunami in areas near the quake.
"There have been no reports of casualties yet but you have to bear in mind the communications with many areas is poor," Spinks told Agence France Presse.
He said the town of Taro had been hit by a large wave and there had been reports of buildings being damaged. The settlement of Lofung had also reported being hit by a large wave with residents evacuating to higher ground, Spinks said.
In Gizo, a town just 45 kilometres from the quake epicentre, waves had caused damage after sweeping beyond the high water mark, he said.
The Solomons has fewer than 500,000 people living on dozens of islands.
It is part of the Pacific "Ring of Fire" where continental plates meet and frequently experiences volcanic and seismic activity.
Ada Akao, from Australia's High Commission in Honiara said the quake was felt in Honiara, the capital of the Solomon Islands, but no buildings in the city appeared to have been damaged, Reuters reported.
"It lasted ... let's say two minutes. Not much damage here. We felt a gentle rock. Nothing bad happened," Akao told ABC radio.
The tsunami warning centre said the size of the earthquake did cause concerns for the potential for a serious tsunami.
"An earthquake of this size has the potential to generate a destructive tsunami that can strike coastlines in the region near the epicentre within minutes to hours," the warning centre said.
Geoscience Australia said it had since revised the quake's strength up from 7.6 to 8.1 on the Richter scale, based on updated calculations.
A Geoscience spokeswoman said the resulting tsunami would be between 10 and 20cm, posing little threat to residents in isolated areas.
"It's not a really big (threat) for the coast of Australia," she said.
The Bureau of Meteorology's National Meteorological and Oceanographic Centre earlier said a possible tsunami could affect Willis Island at 8.30am and Cooktown in far north Queensland about 9.30am.
Geoscience duty seismologist David Jepsen said the quake had occurred in an area of frequent seismic activity.
There had already been one aftershock, the strength of which had not yet been determined, Dr Jepsen said.
"It's on the plate boundary between the Pacific and Asian plates, so these quakes are common," he said.
The quake struck at 7:40 am local time (2040 GMT Sunday) and was centred about 350 kilometres (220 miles) west-northwest of the capital Honiara at a depth of 10 kilometres, the US Geological Survey and Hong Kong Observatory said.
The Pacific nation, 2,575 kilometres east of Australia, has fewer than 500,000 people living on dozens of islands.
It is part of the Pacific "Ring of Fire" where continental plates meet and frequently experiences volcanic and seismic activity.
The weather bureau says the threat to the Queensland coast posed by an undersea earthquake near Solomon Islands has eased.
The Bureau of Meteorology's latest tsunami alert said the weather station on Willis Island, off the north Queensland coast, reported no noticeable affect of waves at 9am, by which time the tsunami was expected to have passed.
"At this stage the threat seems to have eased," the bureau reported.
ut warnings will be maintained. The bureau says dangerous waves and currents may affect beaches, harbours and rivers. The Queensland State Emergency Service has advised that people should stay away from low lying coastal areas.
