What comes to your mind when you hear the word "Antarctica?" Glaciers, ice, frost, snow, uninhabitable desert - well, you get it. But how about a lake of bubbling lava hidden deep under the ice? An unlikely connection, right? But that's actually a very real and highly unusual Antarctic phenomenon that was just recently discovered. Until recently, people only knew about 7 such lakes bubbling in different regions of our planet. But here we go now: in July 2019, scientists discovered one more! It is resting in the crater of the active volcano. Even though it's not the largest lava lake in the world, it’s still very impressive, with a diameter varying from 300 to 700 feet! TIMESTAMPS: How hot is this lake? 1:55 Why it was only recently discovered 2:32 What's so unusual about Mount Michael's lava lake? 3:48 Lava lake in the Democratic Republic of Congo 6:04 - Why you need to be extra cautious with it 6:26 - The catastrophe of 1977 6:53 Lava lake in the coldest place on Earth 7:49 Disappeared lava lakes 8:53 #volcanoes #antarctica #brightside SUMMARY: - Already in the 1990s, scientists noticed some weird thermal anomalies occurring around the crater of the volcano. Unfortunately, at that time, the resolution of the photos was too bad to prove the existence of the lava lake. - Antarctica’s lava lake is resting in the crater of the active volcano, Mount Michael, located on small, remote Saunders Island in the South Atlantic Ocean. - One of the main reasons why the lava lake was only recently discovered is its remote location. - Anyway, it would have taken scientists much longer to confirm their lava-lake suspicions but for the high-resolution satellite images. Before that, they only knew that a temperature anomaly on Saunders Island did exist. - The thing is that hundreds of volcanoes erupt by spitting out lava, which then gathers into small lakes and pools of molten rock. - Sulfur dioxide, steam, and carbon dioxide keep temperatures inside craters so high, that the lava constantly stays in its liquid state. - Since 1882, the Mount Nyiragongo volcano has erupted a whopping 34 times! What's more, some of these eruptions, in the form of a bubbling lava lake, lasted for years. - You'll need to be extra cautious with this treacherous volcano and the lava lake it contains. It emits extremely toxic carbon dioxide gas that seeps right up from the ground. - Mount Erebus is situated in the coldest place on Earth - and still hosts a lava lake with the habit of launching lava bombs (which are flying globs of molten rock). - Interestingly, Mount Erebus follows its own pattern - the volume of its gas plumes falls and rises every 5 to 18 minutes. - As for Kilauea in Hawaii, it's one of the world's most active volcanoes, and it used to host not just one, but two lava lakes! - Both of these lakes remained molten and active until they just... disappeared in 2018!
