Study challenges widely accepted theory of Yellowstone formation

Understanding the complex geological processes that form supervolcanoes could ultimately help geologists determine what triggers their eruptions. A new study using an advanced computer model casts doubt on previously held theories about the Yellowstone supervolcano’s origins, adding to the mystery of Yellowstone’s formation.

“Our model covered the entire history of Yellowstone volcanic activities,” said Lijun Liu, a geology professor at the University of Illinois. Liu’s computer model accounted for the last 40 million years, prior to even the earliest signs of Yellowstone’s volcanism.

Yellowstone is one of the largest remaining active supervolcanoes. True to its name, a supervolcano is capable of erupting on a much larger scale than an ordinary volcano. The origins of Yellowstone are still under much debate. One of the most prevalent views is that Yellowstone’s supervolcano was formed by a vertical column of hot rocks rising from the top of the earth’s core, known as a mantle plume.

“The majority of previous studies have relied on conceptual, idealized models, which are not physically and geologically accurate,” Liu said. Some recent studies reproduced key geophysical factors in a laboratory setting, including a rising plume and a sinking oceanic plate. However, these studies failed to account for the comprehensive set of geological variables that change over time, influencing the volcanic history.

“Our physical model is more sophisticated and realistic than previous studies, because we simultaneously consider many more relevant dynamic processes,” Liu said.

Using the Blue Waters supercomputer at the National Center for Supercomputing Applications at the U. of I., one of the fastest supercomputers in the world, Liu’s team created a computer model that replicated both the plate tectonic history of the surface and the geophysical image of the Earth’s interior. This study is the first to use a high-performance supercomputer to interpret the layers of complicated geophysical data underlying Yellowstone, Liu said.

The main goal of the study was to examine whether the initiation and subsequent development of the Yellowstone volcanic system was driven by a mantle plume. The simulated data showed that the plume was blocked from traveling upward toward the surface by ancient tectonic plates, meaning that the plume could not have played a significant role in forming Yellowstone, Liu said.

The researchers published their findings in the journal Geophysical Research Letters.

The researchers also examined many other factors that could have played a role in forming Yellowstone. These simulations discounted most of the other theories of Yellowstone’s origins, Liu said. As a result, formation of the Yellowstone volcanic system remains mysterious.

Supervolcanoes are hazardous natural phenomena that evoke public concern, partly because their formation is not well understood. While this area of research is still far from predicting eruptions, Liu said, improving the fundamental understanding of the underlying dynamics of supervolcano formation is key to many future applications of relevant geophysical knowledge.

“This research indicates that we need a multidisciplinary approach to understand complicated natural processes like Yellowstone,” Liu said. “I know people like simple models, but the Earth is not simple.”

Seems pretty regular. Like "Old Faithful". Seems we're just about due another blast. Give or take a few thousand years.

I've had this strong notion, for quite some time, to move to the Southern Hemisphere ....

So does Iceland, but things are a bit bubbly underground there.

NASA considers puncturing Yellowstone supervolcano to save life on Earth

by Greg Beach

A new study from NASA’s Jet Propulsion unit has determined that the threat of a supervolcanic eruption to life on Earth may be more pressing than any interstellar collisions. An eruption of a supervolcano, like that found in Yellowstone National Park in the United States, could trigger a collapse of the global agricultural and economic systems and result in the deaths of potentially millions of people. Although NASA scientists can’t predict when such an event would occur, they have already begun preparing a preventative measure: drilling into the magma chamber of a supervolcano to cool it down.

Although the potential consequences of a supervolcano eruption would be devastating, earthlings should rest easy knowing that the chance of such an eruption taking place this year is roughly 1-in-730,000. Even then, there is a chance that it could be nothing more than a little lava flow. Nonetheless, NASA scientists are preparing to deal with the problem before it happens.

Magma eruptions occur only when it is thoroughly melted by intense heat; cooling magma down by 35 percent would prevent a supervolcano from erupting. To do this, the scientists envision using a drill to puncture above the chamber, where hydrothermal fluids are pushed to the surface. Adding water in this highly pressurized environment would be sufficient to cool the magma.

To avoid fracturing the surrounding rock and potentially setting off an eruption, NASA scientists suggest drilling into the supervolcano from below. It is estimated that such a plan would cost around $3.5 billion, although governments would be encouraged to think of this as an investment: Excess heat could be captured and transformed into clean energy.

"To avoid fracturing the surrounding rock and potentially setting off an eruption, NASA scientists suggest drilling into the supervolcano from below.

So they're going to puncture above the chamber by drilling into it from below? Adding water to a high temperature chamber that is already under tremendous pressure seems insane because it's more likely to create an explosive steam cloud expanding rapidly and greatly increasing the overall pressure, enough to cause an eruption, I would think. But then, I'm not a NASA scientist, so what do I know?
