American Super Volcano Under Yellowstone National Park Sprawling over Projections

American Super Volcano

U.S. scientists report in December 2013 as the first week Super volcano under Yellowstone National Park in the U.S. is significantly larger than previously estimated earlier. According to the study , the magma chamber is 2.5 times larger than previous estimates and projections than the previous caravan is spread over 90 kilometers and 200-600 cubic kilometers of rock are formed by melting . The findings presented at the meeting of the American Geophysical Union in San Francisco were.

According to the report , the Yellowstone super volcano is still spreading, which could have catastrophic consequences . There are only three major eruption so far . The first and second explosion occurred 13 million years ago was about 2.1 million years ago , while the third was 640,000 years ago . North America 's ash explosions had affected the Earth's climate .

For a map of the magma chamber , located near Park A team of scientists used seismic network found on the ground through earthquake measuring seismic waves in Yellowstone and the surrounding area . These Tnrgen slow due to hot and melted for any content that travel is so down to earth scientists measure it helps .

According to findings by scientists at a depth of 2 kilometers and 15 kilometers giant , magma chamber has been identified and it is 90 kilometers long and 30 kilometers wide caravan .
