“I don’t think we know exactly what to expect.” While scientists may not know exactly what to expect, they have an idea-and most say it’s unlikely to be doomsday. Steve Anderson, a volcanologist and earth sciences professor at the University of Northern Colorado. “The big question is if Yellowstone started shaking tomorrow, what is there to expect?” says Dr. And if it does, there is concern about how intense that eruption may be. The period of slow, steady rise has many scientists wondering whether Yellowstone might erupt in the near future. However, in 2010 the land began to subside. Volcanologists, who have been measuring this activity since 1923, say the ground rose about 25 centimeters (9.8 inches) between 20. When the magma begins to solidify and cool, the ground falls. As magma feeds into a magma chamber, or reservoir situated about 6-10 kilometers (4-6 miles) beneath the park, the ground swells. The ground above the Yellowstone supervolcano sits on a hot spot made of molten and semi-molten rock called magma. The volcano itself is actually located in northwestern Wyoming, which is where the bulk of Yellowstone is contained. This giant is the “ supervolcano” that lies beneath Yellowstone National Park, the wildlife and forest preserve positioned on a sprawling expanse that extends through the states of Wyoming, Idaho, and Montana. But when it finally awakes it may roar and heave with unprecedented force. Though it stirs occasionally, it has not risen from slumber in nearly 70,000 years. He recently took it with him to the Philippines to share with his relatives there.A sleeping giant is nestled in the western part of the United States. I thought it was very well done and my son just loves it. Lots of original film on the scene at the time. They share what it was like to have to make decisions affecting the lives of so many people and what they went through in trying to determine what the volcano was doing and when would it erupt. I really liked this because the story is told from the viewpoint of the US Geological Survey team and the military leaders on the American bases near to the volcano at the time and the Local people who were greatly affected by the eruption. This was especially interesting for us since my wife is from the Philippines and I have been through the area affected by the volcano. This documentary is about the 1991 eruption of Mount Pinatubo in the Philippines, one of the greatest eruptions in the last 80 or 90 years. I bought this DVD because my 6 year old son has a fascination with volcanos and earthquakes and in the process I've gotten hooked on them also.
