“The world’s largest acidic geyser is putting on a show again, erupting for the first time in six years after a quiet hiatus, officials at Yellowstone National Park say. The Echinus Geyser — located in the park’s famous Norris Geyser Basin — had been in slumber since 2020, and it’s unknown whether the eruptions will continue into the summer. Researchers say geysers can sometimes become active for a month or two before falling dormant again. ‘Geysers are always turning on and off. That’s Yellowstone being Yellowstone!’, the US Geological Survey wrote on X. A geyser is a spring of water which has been heated geothermally, and which erupts at various rates. It is formed from a tube-like hole that goes down into the Earth’s surface and is filled with water. When the water at the bottom, which is near molten rock called magma, heats in the tube it begins to boil and is forced upwards and erupts. After eruption, the water slowly goes back down into the tube. Then the process starts again.” (03/03/26)
