New underground tunnel discovered in Son Doong Cave

A new underground tunnel, which is far below the sea level, has been discovered in the world’s largest cave Son Doong in the central province of Quang Binh.

The information was disclosed at an international press conference on the latest diving expedition inside the cave in Hanoi on April 9.

The research diving trip made by a team including British divers Richard Stanton, John Volanthen, Jason Mallison and Chris Jewell, who were members of the rescue team saving the Thai football team trapped in Thailand's Tham Luang Cave last year.

The research began this month and the divers started work at the end of the river inside Son Doong and went further into a water passage. The trip was expected to prove that the passage connected Son Doong and the Thung Cave, which is a cave of the same type laying 600m away.

The expectation was based on results made by the British Cave Research Association’s team, who were the first to explore Son Doong, following a survey they did in 2010.

However, the passage was actually not in a straight line and it went deeper underground, said Volanthen at the media briefing. He said the divers found a hole inside the passage and that hole leads to a tunnel.

Unfortunately, normal air compressors that the divers had during the research trip were unable to keep them safe for further diving and the divers had to end their first visit to the tunnel.

“The actual depth of the tunnel could be 100m or more. I managed to reach a depth of 77m and couldn’t go further due to the failure of equipment,” said Mallison.

However, according to Howard Limbert, Mallison’s remarks helped prove that Son Doong did not end where the river poured into the passage but expanded into the underground tunnel. Limbert was a member of the British caving team who first explored the cave. Today he is the technical manager of Oxalis Adventure Tours, the sole tour provider into the giant cave.

Howard appraised the early success in finding the tunnel and described the diving as one of the most “difficult and challenging tasks”.
