A Kiribati government team has gone to Kiritimati island to assess the damage caused by a huge wave that struck the island two weeks ago.
Four men died instantly when a five-metre wave hit their car by the port.
The team is led by the permanent secretary of the President, Saitofi Miika.
It will spend one week on the island to find out exactly what happened and assess the extent of the damage.
Retaake Tekabwebwe from the Kiribati Police headquarters says their officers on the island are also carrying out an investigation into the deaths of the four men.
The Met Office had issued no alert at the time, reportedly unaware of the risk to the wharf area.
