Diving Tragedy: Cave Suction Theory Emerges
20 May
Summary
- Divers may have been sucked into a cave by strong currents.
- A Venturi effect is hypothesized to have caused the suction.
- A separate rescue diver also died from decompression illness.

Five Italian divers who tragically drowned during an expedition in the Maldives may have been victims of a strong cave current, according to a new theory. The elite divers were exploring the 'shark cave' when they disappeared. Investigators are considering the possibility that a powerful current, potentially a 'Venturi effect' created by the cave's unique entrance, may have sucked them into the cave.
This theory suggests the divers, including Monica Montefalcone and her daughter Giorgia Sommacal, could have been caught off guard. Their experienced level made their disappearance perplexing, but the Venturi effect, causing a pressure drop and a vacuum, could explain how even skilled divers were trapped. One hypothesis is that one diver was pulled in, and the others attempted a rescue.
Recovery efforts have been perilous, with two bodies recovered and two still trapped. The mission has been further marred by the death of a Maldivian military rescue diver from decompression illness, bringing the total death toll to six. Italian authorities have launched a manslaughter probe into the incident.
