Yellowstone
Here's what I learned today:
The upward movement of the Yellowstone caldera floor-almost 3 inches (7 centimeters) each year for the past three years-is more than three times greater than ever observed since such measurements began in 1923.[16] From mid-Summer 2004 through mid-Summer 2008, the land surface within the caldera has moved upwards, as much as 8 inches at the White Lake GPS station.[17] The U.S. Geological Survey, University of Utah and National Park Service scientists with the Yellowstone Volcano Observatory maintain that they "see no evidence that another such cataclysmic eruption will occur at Yellowstone in the foreseeable future. Recurrence intervals of these events are neither regular nor predictable.".[8]
