'Action needed'
'Villages flooded'
Solomons police spokesman Mick Spinks said there have been sketchy reports of damage caused by a tsunami in areas near the quake, in the New Georgia Islands region in the west of the Solomons.
Sgt Godfrey Abiah of the Solomons police force said the waves had hit the town of Gizo, in the New Georgia Islands region in the west of the Solomons, which was only 45km (25 miles) from the epicentre of the quake.
"There have been no reports of casualties yet but you have to bear in mind the communications with many areas is poor," he told the AFP agency.
He said police in Gizo had been urging people to leave coastal areas when the tsunami hit, but communications were lost soon afterwards.
"We have lost radio contact with the two police stations down there and we're not getting any clear picture," he told The Associated Press.
Julian McLeod, a Solomon Islands disaster management official, said: "Two villages were reported to have been completely inundated.
"We have received reports of four people missing."
Japanese public broadcaster NHK reported that at least three people had been killed.
The Pacific Tsunami Warning Center said authorities in countries with coastlines in the region should take appropriate action.
