Yellowstone: the most dangerous volcano in the world is moving

May 21, 2011Yellowstone National Park, Wyoming— The nation's oldest park — and one of the most studied. The interest is not just in its outlook and amazing wildlife, but also below the volcanic animal park.
Yellowstone sits on one of the largest active volcanoes in the world, one capable of imposing spending in most of North America.
Scientists monitor it using a network of seismic sensors and GPS. Professor Emeritus Robert Smith of the University of Utah — one of those scientists. Geophysicist, Smith a leading expert on the Yellowstone super volcano. "We monitor it in real time for earthquake swarms and are based deformation."He says that the park is in constant motion.
Visitors can not see it, but the ground at their feet is moving up and down as magma pressed to thin crust and causes a lot of geysers in the park action.
The changes are most evident in the Basin Norris Dzheizera. Henry Hisler, Yellowstone Park geologist said, "It changes daily.
Sometimes it's hard to keep up with the changes around the boardwalk, because it affects the safety of visitors and employees.
Why all the hydrothermal features here?"Heasler continued," The geysers? Pots of dirt? Steam vents? Hot Springs? This is because of the heat beneath our feet."The heat from the volcano — the offender. And beginning in 2004, volcanic pressure caused an amazing increase in the Park: three inches per year for five years. Professor Smith said, "It's — a lot of lifting, and it's on the field, it's across the Yellowstone caldera — 50 miles long from the lift."" If you go under the rubber sheet, "said Hisler description recovery," and increase your thumb, it's not simply exposes where your thumb, there is like a slope to it."In fact, since the earth bulged, Yellowstone lake obliquely enough that his water gushed trees on the southern arms. And now, the land is reduced. And the decline has raised a whole new set of issues for researchers. "Why trees do not appear again?"Asked Hisler. "We do not know."They see the data as well as the geothermal features of the park for clues. From time to time, those geologists see themselves, doctors, patient monitoring. In this case, the patient took a deep breath (between 2004-09), and now it is free. What is clear from many observations. Unanswered question, "Why?"- ABC 4
