Explorers confirm Czech Hranice Abyss deepest underwater cave on the planet


A team of explorers has just confirmed that Hranice Abyss, located in the eastern part of the Czech Republic, is deepest underwater cave on the planet. A Czech-Polish expedition, led by the legendary Polish diver Krzysztof Starnawski, descended deep into the flooded limestone abyss Hranicka Propast this week and found it to be far deeper than previously thought. The underwater cave is 404 meters deep, making it the deepest underwater cave in the world, 12 meters deeper than the previous record holder, 392-meter-deep Pozzo del Merro in Italy. News of the discovery appeared in the National Geographic which co-funded the expedition.
