Scientists say the geologic record shows that it has blown, or erupted, every 600,000 years. It has not erupted now in 640,000 years and many believe it is not only overdue, it is getting ready to blow.
There are several indications this may be true, and the Idaho Observer reported some of them in a recent edition. Among them:
The next eruption could be 2,500 times the size of the 1980 Mount St. Helens eruption.
Volcanologists have been
tracking the movement of magma under the park and have calculated that, in parts
of Yellowstone, the ground has risen over seventy centimeters this century.
In July, 2003, Yellowstone Park rangers closed the entire Norris Geyser Basin because of deformation of the land and excessive high ground temperatures. There is an area that is 28 miles long by 7 miles wide that has bulged upward over five inches since 1996, and this year (2003) the ground temperature on that bulge has reached over 200 degrees (measured one inch below ground level).
'There was no choice but to close off the entire area,' the Idaho Observer reported. "Everything in this area is dying: The trees, flowers, grass and shrubs. A dead zone is developing and spreading outward. The animals are literally migrating out of the park.
'In late July, one of the Park geologists discovered a huge bulge at the bottom of Yellowstone Lake. The bulge has already risen over 100 feet from the bottom of the lake and the water temperature at the surface of the bulge has reached 88 degrees and is still rising, the Idaho Observer reported.
'Keep in mind that Yellowstone Lake is a high mountain lake with very cold water temperatures. The Lake is now closed to the public. It is filled with dead fish floating everywhere. The same is true of the Yellowstone river and most of the other streams in the Park. Dead and dying fish are filling the water everywhere.
The Observer reported that 'many of the picnic areas in the Park have been closed and people visiting the Park usually stay but a few hours before leaving since the stench of sulfur is so strong they literally can't stand the smell.'
According to the Unknown Country website, Lisa Morgan, the geologist leading a U.S. Geological Survey team studying the bulge beneath Yellowstone Lake said, "it could be the precursor to a hydrothermal explosion." Hydrothermal explosions take place when water is superheated by lava and they can be extremely violent.
While dangerous, they don't come close to the power of super volcanoes.
About 640,000 years ago, the Yellowstone basin was born out of the explosion of a supervolcano that deposited ash as far away as Texas.
There have been claims made that another such explosion is about to happen, but USGS scientists claim that there is no evidence for this whatsoever, but a geothermal explosion that would affect Yellowstone Park and the surrounding area appears to be a possibility.
'The irony of all this is the silence by the news media and our government,' the Observer commented. 'Very little information is available from Yellowstone personnel or publications. What mainstream news stories do appear underscore the likelihood of a massive volcanic eruption.'
The Observer said that, though geologists publicly admit Yellowstone is “overdue,” they have been quoted as stating another massive magma release may not occur for 100,000 or 2 million years. Others close to the story are convinced that a massive eruption is imminent.
The Observer again: 'A source that has demonstrated first-hand knowledge of the park's history and recent geothermal events stated the following: “The American people are not being told that the explosion of this 'super volcano' could happen at any moment. When Yellowstone does blow, some geologists predict that every living thing within six hundred miles is likely to die. The movement of magma has been detected just three-tenths of a mile below the bulging surface of the ground in Yellowstone raising concerns that this super volcano may erupt soon.”
