Albania

Albania has just been crowned on the world geological map. And big. There, on the border with Greece, a tens of meters deep, an expedition has identified the largest underground thermal lake on the planet. His name, Neuron. Its figures: more than 183 m long, 42 wide and sufficient water to fill A few Olympic pools. The finding confirms the scope of a discovery that dates back several years ago but whose relevance has only been confirmed now, with the help of a Lidar scanner. Its history is as curious as its size. “A steam column”. To understand the scope of the discovery you have to go back a few years ago, at 2021 and 2002, when a team of Czech scientists launched Vromoner, in southern Albania, near the border with Greece. The area resulted especially interesting For geologists because for years the convulsive political context of Balkans had hindered that scientists could thoroughly examine it. There the experts found a vast underground system of thermal sources thanks to a curious track: a steam stream. “From the high vapor column that rose from the limestone massif we managed to locate a chasm of more than one hundred meters deep,” Marek Audy tellsHead of the expedition. They called her atmos. When exploring it, they took an even greater surprise (literally): they found an intense thermal activity and a “great lake.” How large and broad it was, however, it became an unknown that then, for technical issues, they could not clarify. A (huge) suspicion. Which I was clear Audy team was that it had found something big, huge. And again both words can be understood in their most literal sense. The team suspected that the water extension that had been located in Albania was the largest underground thermal lake in the world, at least among those known today. Hence, later the researchers returned to the Sima in a new expedition provided with a reinforced technical arsenal. Thanks to the support of the Neuron Foundation, which contributed funds, the geologists achieved a special lidar scanner and the software necessary to measure the area. The objective of the researchers –The Neuron Foundation reported Before the expedition left – it was to make a map, a 3D model of the underground cave and the lake and even collect samples of animals from the banks. The result of that incursion has been waiting, but it was worth it: today those responsible presume having identified the largest underground thermal lake in the world. A “unique” lake. In a wink to the foundation that supported the project to the lake, Neuron has been baptized. What surprises however is not its name, but its size: 138.3 meters in length by 42 wide with a circle of 345 m. Inside it hosts around 8,335 m3 of thermal mineral water and those who have had the opportunity to visit it highlight the show of its dome, three times greater than that of the main room of the Prague National Theater. “The phenomenon has been subject to a thorough hydrogeological study to confirm its singularity,” The Foundation stands outwhich emphasizes that it is a “unique” lake. And how did they measure it? The team did not start from scratch. Richard Bouda, photographer and member of the expedition, Explain to Euronews that during the first visit they had already prepared a “basic map” with the resources they had. When they returned they did it, however, with a mobile lidar scanner and the system Geoslam which allowed them to precisely probe the cave and the lake. Not just that. They also traced a detailed map of Atmos, including other caves, such as sulfur. “We believe that this discovery will help protect the area and to better understand hydrological flows. Until now, nobody knew precisely how these groundwater connect to the surface,” Bouda comments. The team also trusts that the finding has an impact on the hydrological and geological studies of the region. Images | Neuron 1 and 2 In Xataka | A cave in France hid a strange rock formation.
