...released last year, the United States Geological Survey (USGS) said possible hazards could include hydrothermal explosions, when steam breaks through the surface and forms a crater. That has happened 26 times in the park's 127 years of record-keeping. The USGS discounted chances for cataclysmic eruption of the caldera, noting that the hot, active magma chamber below Yellowstone has turned into "largely crystallized mush." But the same study also said: "Depending on the nature and magnitude of a particular hazardous event and the particular time and season when it might occur, 70,000 to more than 100,000 persons...
...Yellowstone Caldera - formed by the massive upheaval 642,000 years ago that spread airborne debris all the way to the Gulf of Mexico - is nowhere close to being extinct. Areas of the park's topography inflate like a bellows because of magma infusing into volcanic chambers about 6 miles below the surface. About 1,000 to 2,000 tremors a year (mostly small) have been recorded since 2004, when interpretation of satellite imagery with GPS readings indicated the caldera had been rising as much as 3 in. a year. The past week's number of tremors - about 400 - is considered...

The National Park Service and local officials would be responsible for civil defense measures and evacuation plans. For now, life goes on. The system is generally automated, and a seismologist at the University of Utah is on call to make sure it's a real event should it be anything unusual...
