Five Italian nationals have died in what officials are calling the worst single diving accident in the history of the Maldives, after a deep cave dive in Vaavu Atoll on Thursday ended in tragedy.
Italy’s foreign ministry, the Farnesina, confirmed the deaths in a statement, saying the group perished while attempting to explore caves at a depth of around 50 metres, or roughly 165 feet. The incident took place near Alimathaa Island, one of the most popular dive sites in the central atolls and a destination long favoured by Italian visitors.
The Maldives National Defence Force said the divers entered the water on Thursday morning and failed to resurface. The crew of their vessel raised the alarm when the group did not return by midday, triggering a major search involving aircraft, speedboats and the coast guard ship Ghaazee. The first body was recovered at 6:13 p.m. local time by safari divers assisting the operation, and was taken to the health centre on the island of Fulidhoo. Military officials said the body was located inside an underwater cave roughly 60 metres long, and that the four remaining divers were believed to be in the same location. The recovery zone was described as extremely high risk, requiring specialist equipment.
Victims Included Renowned Marine Biologist and Her Daughter
Italian media identified the victims as Monica Montefalcone, a 51-year-old associate professor of ecology at the University of Genoa, and her 20-year-old daughter, Giorgia Sommacal. The University of Genoa confirmed the death of Montefalcone, who was an internationally recognised marine ecology researcher attached to the Department of Earth, Environment and Life Sciences and a familiar face on Italian television. She had led major marine conservation programmes and, according to Italian reports, served as scientific director of an island monitoring campaign in the Maldives.
The other three victims were named as Muriel Oddenino, a researcher from the Turin area, and diving instructors Gianluca Benedetti and Federico Gualtieri. Benedetti, who was also reported to be an operations manager and boat captain, was among the most experienced members of the group.
Conditions and Vessel
The group was travelling aboard the Duke of York, a foreign-operated liveaboard diving yacht that runs year-round itineraries across the Maldivian atolls and caters heavily to Italian clientele. The 36-metre vessel offers free nitrox to certified divers and is rebreather-friendly, according to its operators.
Police said weather in the area was rough at the time of the dive, with winds reported between 25 and 30 miles per hour. The Maldives Meteorological Service had issued a yellow warning for passenger boats and fishing vessels covering the dive zone, which remained in effect into the evening. Alimathaa lies in Vaavu Atoll, approximately 65 to 100 kilometres south of the capital, Malé.
Investigation and Possible Causes
Maldivian authorities have opened an investigation, and no official cause of death has been confirmed. Local and Italian dive experts have pointed to several possible factors common in fatal deep-cave incidents at such depths. Italian dive master Maurizio Uras, speaking to news agency AGI, said that at depths beyond standard recreational limits, oxygen in a breathing mixture can become toxic if blends are not precisely calibrated, with technical dives typically requiring helium and reduced oxygen concentrations.
Other specialists cited the psychological and environmental pressures inside a deep cave, where a single equipment failure, a panic response or reduced visibility from disturbed sediment can rapidly cascade into a fatal sequence for an entire group. Past accidents at similar depths have also been linked to contamination of breathing gas inside cylinders. Investigators are expected to examine the divers’ equipment, gas mixtures and dive profiles as part of the inquiry.
Consular Response
The Farnesina said the Italian Embassy in Colombo, which oversees consular matters for the Maldives, has been engaged with the case from the outset and is in contact with the victims’ families to coordinate assistance and repatriation. The four other Italians are reported to have come from Poirino, Milan, Genoa and Padua.
The Maldives, a string of nearly 1,200 coral islands scattered across the equator, draws hundreds of thousands of divers each year to its reefs, channels and wrecks. Vaavu Atoll in particular is known for its dramatic underwater channels, known locally as kandu, where strong currents attract sharks, manta rays and large pelagic species. Officials in Malé described Thursday’s incident as the deadliest single diving accident on record in the country.
