This new discovery and new record has just been announced following latest surveys by Laurens Smets, an expert on volcanic caves from the Netherlands.

Explorers are now completing a 3D map for the Cave C7 system.

Earlier on November 28, experts also found some branch-worked caves with a total length of 175 metres inside this cave.

Located in Krong No District, Krong No Volcanic Cave is a system about 10 kilometres long of volcanic caves in basalt. 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 discovered at Krong No Volcanic Cave.

The Krong No Volcanic Cave system is well intact. During the process of surveying and studying the cave system, scientists discovered traces of the residence of prehistoric tribes from about 6,000–7,000 years ago.
