Yellowstone National Park is an area of outstanding natural beauty. Millions of people go each year to see the geysers,fumaroles and hot springs that occur within the park. Underneath Yellowstone the magma that heats the wonders at the surface is not so benign. The molten rock churns and increases the pressure on the ground above it causing it to rise over time.
Dr. Robert Smith, University of Utah explains as follows:
“Anytime you come to Yellowstone you have to drive uphill,” explained supervolcano scientist Dr. Robert Smith. “And the reason is this giant plume of magma is very hot, therefore it’s ebullient, it’s low density and it just lifts the surface up.”
“These giant eruptions in Yellowstone – the supervolcano, if you wish — probably last many, many months, maybe even years,”
“If we were to have another big eruption, it would affect a large area, on the order of several states,” Smith said.  (source)
Dr Jamie Farrell, also from the University, added:
“We record earthquakes in and around Yellowstone, and we measure the seismic waves as they travel through the ground,”
