⠀
New research from an international team of scientists has discovered that supervolcanoes here on Earth can remain active and threatening for thousands of years following an initial super-eruption.⠀
⠀
Supervolcanoes can occur over both hotspots like Yellowstone and in subduction zones, such as the one at Lake Toba in Indonesia. That particular eruption occurred about 75,000 years ago and wiped out most of humanity at the time. It also led to a volcanic winter that dropped the worldwide average temperature about 4˚C. The ash from that eruption was found as far away as East Africa.⠀
⠀
Now, scientists studying that supervolcano eruption have found that the volcano continued to erupt. They examined minerals such as feldspar and zircon (my personal choice in this year’s Mineral Cup) and analyzed the gas inclusions of argon and helium. Lead author Martin Danišík explains: Using these geochronological data, statistical inference, and thermal modeling, we showed that magma continued to ooze out within the caldera, or deep depression created by the eruption of magma, for 5,000 to 13,000 years after the super-eruption, and then the carapace of solidified left-over magma was pushed upward like a giant turtle shell. ⠀
