There has been no sign of a Papua New Guinea family of five which was swept away by the tsunami following yesterday's earthquake.
The family, which included two children was on the coast of Rossel Island in the Louisiade group of islands off the eastern tip of the PNG mainland when the tsunami hit yesterday morning.
Our correspondent, Alex Rheeney, says searches for the five continued throughout yesterday without success.
He says the tsunami caused significant damage on Rossel and also on the adjacent coral atolls of Budi Budi.
They lost all their houses as well as their food gardens. The only school, the only primary school that serves the coral atolls has also been washed down by the huge waves yesterday morning. The good thing is there were no kids in the classroom when the waves went through.
