Disclaimer: I'm no Danish teaching expert, I just happen to be an Icelander who was forced to learn Danish as my second language - and although I always got very good grades in Danish, I was never good in Danish: can't speak it, can't understand a Dane - I can maybe read it a little bit...
University of Utah geology and geophysics professor Fan-Chi Lin said the blob-shaped lower magma reservoir in Earth's lower crust is located 12 to 28 miles (20-45 km) under Yellowstone, with a volume of 11,500 cubic miles (46,000 cubic km), or 11.2 times the volume of Arizona's Grand Canyon.
The newly discovered magma reservoir is big enough to fill up the Grand Canyon 11 times and is several times larger than the shallower, long-known magma chamber beneath Yellowstone. Researchers on Thursday said they used a technique called seismic tomography to a produce for the first time a complete picture of the volcanic plumbing system at Yellowstone, from the Earth's mantle up to the surface.
