“Ground said rising at Yellowstone Park

WASHINGTON -- Yellowstone National Park, once the site of a giant volcano, has begun swelling up, possibly because molten rock is accumulating beneath the surface, scientists report.
Smith and colleagues report in Friday's issue of the journal Science that the flow of the ancient Yellowstone crater has been moving upward almost 3 inches per year for the past three years.
That is more than three times faster than ever observed since such measurements began in 1923, the researchers said.
The volcano at Yellowstone produced massive eruptions 2 million, 1.3 million and 642,000 years ago, all larger than the 1980 eruption of Mount St. Helens.”
