A German jazz singer has disappeared following a scuba dive in what is said to be the South Pacific’s largest underwater cave.
Marina Trost, 40, had been exploring the Cathedral on the northern tip of ‘Eua, a small island in Tonga, on 11 August. She had dived from a whale-watching boat with another woman and a dive-guide, who returned to report that Trost had left them and ascended some time earlier.
Police and local divers subsequently scoured the area but without success, in deteriorating weather conditions.
Trost’s weightbelt and later a fin were found on the floor of the Cathedral, which is described as a well-lit 100m by 50m amphitheatre with a maximum depth of 30m. The entrance is at 28m, and several tunnels extend from the main chamber.
