Scientists model magma chambers under Yellowstone volcano

Using supercomputers, American scientists have modelled the behaviour of two magma chambers hidden below the surface of Yellowstone supervolcano, where the last major eruption happened 6.3 lakh years ago. At depths of 5-10 km, opposing forces create a transition zone where cold, rigid rocks give way to hot, ductile and partially molten rock from depths of 45 km, researchers found.
