In December 13, the Management Board of UNESCO Global Geopark Dak Nong said that the C7 volcanic cave in the Krong No volcanic cave system (Dak Nong province) has just set a new record for length.
Mr. Laurens Smets, a Dutch volcanic cave expert, has just sent a written notice to the Dak Nong UNESCO Global Geopark Management Board about the results of measuring and drawing additional diagrams of the C7 lava tube cave which is the longest in Southeast Asia is located in the Krong No volcanic cave system. According to the announcement, the newly established length of cave C7 is 1,266m. Previously, through the survey of cave C7 - the longest volcanic cave in Southeast Asia, the team of experts discovered some new branches - cave C7 with a length of more than 1,240m.
Currently, researchers are continuing to perfect the 3D rendering of cave C7 system. Cave C7 is recognized by international scientists as the longest volcanic cave in Southeast Asia.
Krong No Volcanic Cave is a system of volcanic caves in basalt about 10km long; set a record for size, length and uniqueness in Southeast Asia, found by scientists in 2014. Krong No volcanic cave system is still quite intact.
The entire system of Dak Nong Global Geopark has hundreds of volcanic caves, but so far, only about 50 caves have been investigated, surveyed and measured. In which, there is a cave more than 1km long, the total length of the caves is more than 10,000m.
Up to now, in Dak Nong Geopark, 5 volcanoes have been discovered, including: Nam Duong Volcano, Bang Mo Volcano (Cu Jut District); Nam Blang volcano, Nam Kar volcano (Krong No district) and Nam Gle volcano (Dak Mil district). The above volcanoes all operate in the form of eruptions, explosive eruptions or both eruptions and explosive eruptions, or fissure eruptions.
