"And these giant eruptions in Yellowstone – the supervolcano, if you wish -- probably last many, many months, maybe even years," Smith said. Not only that, they're huge, thousands of times as large as Mount St. Helens.Read the hopeful comments. It's a push whether they are for, or against the eruption. Ghosts of Harry R. Truman and Woody Harrelson!
Smith and his students use seismographs to map the magma pool underneath Yellowstone's volcano and satellites to determine how much the land swells or bulges. They found that the magma is, "2.5 times larger than we had originally imaged," Smith said. The magma movement is signaled by earthquakes. Smith mentioned the 4.8 magnitude Norris-area earthquake that damaged Lake Hotel last spring. "It's the biggest earthquake in 30 years."
So, how likely is it that the big one will blow soon? "If we were to have another big eruption, it would affect a large area, on the order of several states,” Smith said. “But, as I said, that probability is very, very, very, very small. In my calculations, it's .0001 percent.

That's one movie I have to see!
Sure is a good thing that no eruption is likely in our lifetimes.
Al Gore warned us about the dangers of global warming.
