Another 175 metres of branch-worked caves have just been found in Southeast Asia's longest volcanic cave, Cave C7, in the central highlands province of Dak Nong.

The Management Board of the UNESCO Global Geopark Dak Nong, announced on November 28 that the findings were made after a team of experts surveyed Cave C7 over the past few days.

With this discovery, the length of Cave C7 has now increased to more than 1,240 metres.

"The experts will conduct measurements and draw a 3D map of the heart of Cave C7," the board said. "It will be a valuable source of scientific data for the province's international geological heritage, adding value to the dossier for the upcoming reappraisal."

Located in Krong No District, Krong No Volcanic Cave is a system of volcanic caves in basalt about 10 kilometres long. It has set a record for size, length, and uniqueness in Southeast Asia.

Since being found by scientists in 2014, some 50 branchwork caves of different sizes and lengths have been found at Krong No Volcanic Cave.

The Krong No volcanic cave system is quite intact. In the process of surveying and studying the cave system, scientists discovered traces of the residence of prehistoric tribes about 6,000-7,000 years ago.
