Divers in the Maldives have recovered the bodies of five Italians who died during a cave diving expedition in Vaavu Atoll, as the victims were identified as marine scientists and a diving instructor who had exceeded recreational diving limits. The bodies were located in a sea cave at a depth of 60 meters (197 feet), according to the Maldivian National Defense Force (MNDF), while One body was found inside the cave on Thursday, and the remaining four are believed to be in the same area.

Dangerous Conditions and Technical Risks

Cave diving in the Maldives is highly technical and dangerous, with risks including strong currents, narrow galleries, and depths far exceeding recreational limits, though the recreational diving limit in the Maldives is 30 meters (98 feet), but the cave where the accident occurred was twice that depth. Local journalists reported that diving accidents in coral-origin caves, particularly in atolls like Vaavu, South Ari, and North Malé, are not uncommon, though usually not fatal.

The cave system is marked by chaotic underwater currents, which can shift direction suddenly and trap divers; And, the narrow passages and lack of light increase the risk of panic and disorientation. A diver experiencing equipment failure. Such as a lamp blackout, could lose their way permanently in the dark.

Search Efforts and a Fatal Rescuer

Search and rescue operations were hampered by rough weather, including a yellow warning issued for boats and fishers. The search was temporarily suspended after a Maldivian rescuer, Sergeant Mohamed Mahudhee, died of decompression sickness on Saturday after being hospitalized. President Mohamed Muizzu traveled to Vaavu Atoll to observe the search efforts.

The victims were identified as Monica Montefalcone, 51, an associate professor of ecology at the University of Genoa; her daughter, Giorgia Sommacal, 20; marine biologist Federico Gualtieri; researcher Muriel Oddenino; and diving instructor Gianluca Benedetti. Benedetti’s body was found near the entrance of the cave, while Montefalcone and Oddenino were in the Maldives on an official scientific mission to study the effects of climate change on marine biodiversity. However, the diving activity was not part of the planned research but was carried out privately.

Causes and Hypotheses Under Investigation

Authorities are investigating the cause of the tragedy, with several hypotheses being considered. These include disorientation, panic, issues with gas mixtures in oxygen cylinders, and oxygen toxicity. The latter could occur if a diver hyperventilates under stress at great depths, potentially leading to collapse.

The group had boarded the Duke of York, a luxury liveaboard yacht designed for diving tourists, from which the five divers departed. The disappearance occurred near Alimatha, an area known for its caverns and steep drop-offs. After the alert, the Coast Guard deployed fast boats and aircraft to begin the search. One body was found inside the cave at a depth of approximately 60 meters, and authorities believe the others are in the same cavity, suggesting a simultaneous incident that prevented any of them from returning to the surface.

The caves around Alimatha are not the same as the inland karst tunnels or cenotes popular with cave divers but are instead complex tunnels through the coral reef. These can become especially dangerous when combined with strong tidal currents, which can push divers deeper into the caves or separate them from one another.

The Italian Ministry of Foreign Affairs confirmed that 20 other Italian citizens aboard the Duke of York were unharmed and received assistance from the Italian Embassy in Colombo, Sri Lanka. The University of Genoa issued a statement noting that Montefalcone and Oddenino were in the Maldives on an official scientific mission but that the diving activity was not part of the planned research and was “undertaken privately.”
