|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 .
