Scientists may have discovered Alaska’s own Yellowstone ‘supervolcano’
Diana Roman of the Carnegie Institution for Science in Washington, DC and her colleagues are due to present their research at the American Geophysical Union (AGU) 2020 Fall Meeting.
Their analyses of the seismicity, localized geology, structure, and thermal and gas emissions of Mount Cleveland and five similar-sized volcanoes in the vicinity, suggest something sinister and subterranean may be lurking in the remote waters of Alaska’s Aleutian Arc.
Preliminary data indicate the potential presence of a massive caldera, or collapsed section of the Earth’s crust which falls into an emptied magma chamber, underneath the six stratovolcanoes are Carlisle, Cleveland, Herbert, Kagamil, Tana and Uliaga.
