Marina Trost (40) from Munich, Germany, has been identified as the woman who went missing while diving off ‘Eua on Sunday, August 11.

Tonga Police in releasing her name today said so far nothing had been found but their search continues. Police could release no further information, while they are investigating the woman's disappearance.

Trost was reported to have been part of a whale watching group that were scuba diving inside the 'Eua cave called the "Cathedral", situated on the northern tip of the island.

The German Consul in Nuku'alofa, Carl Sanft, said the woman's disappearance remained unexplained. He said that she came to Tonga with a group that was filming. He was told that she was scuba diving with another woman and their tour guide in the cave. Marina did not return to the boat, which was waiting outside of the cave, but her diving weight was found in the cave.

He said the missing woman's family in Germany had been contacted, and that it was a very difficult time for them to be far away in these circumstances.
