Yellowstone volcano hits more than 70 earthquakes – will it explode? | Science News
According to USGS monitoring services, 73 earthquakes have hit Yellowstone in the past 28 days. This equates to roughly three earthquakes per day on average, with the strongest magnitude of 2.8 recorded on June 14. However, some experts warn that it is not necessarily the magnitude of the earthquake that indicates an upcoming volcanic eruption, but more than a quantity of them.
“If you get swarms underneath a working volcano, the working hypothesis is that magma moves upward beneath it there,” said Scott Burns, Professor of Geology at Portland State University Honorary Scott.
But others disagree about whether an earthquake swarm near the volcano could be a sign of things to come.
Jimmy Farrell of the University of Utah in Salt Lake City thinks this is just part of the natural cycle of the Yellowstone volcano, saying: “Earthquake swarms are fairly common in Yellowstone.”
The Yellowstone National Park service said the area usually has about 700 earthquakes a year.
At the highest level, Yellowstone can experience up to 3,000 earthquakes per year.
The US Geological Survey says: “Almost all earthquakes in Yellowstone are failed failure events that occur when rocks are broken by crust pressure.
Although we have been looking at Yellowstone for years, no one has yet identified the “long-term events” that are usually attributed to the magma movement.
“If LP events are observed, this will not mean that Yellowstone prepares to explode. LP earthquakes usually occur in other volcanoes in the world, including those in California, which have not exploded for centuries or thousands of years.”
The Yellowstone volcano eruption, located in the state of Wyoming, America, last erupted on a large scale 640 thousand years ago.
According to the U.S. Geological Survey, the chances of a Yellowstone eruption are about one in 730,000.

As 640,000 years have passed since the last major eruption, Yellowstone is nearing an explosion – but it may still be thousands of years away.
However, experts are preparing for the worst now, and are studying how to prevent a major eruption, which could instantly wipe out large swaths of the United States.
A NASA employee believes he has found a unique way to stop a major eruption – by feeding cold water in magma rooms in Yellowstone.
NASA engineer Brian Wilcox hopes to stave off the threat of super eruption that cools magma in rooms inside the volcano.
About 60 to 70 percent of the heat generated by Yellowstone leaks into the atmosphere, but the rest builds up inside. If accumulated enough, it can lead to eruption.

By drilling 10 kilometers into Yellowstone, a NASA employee believes it will be possible to pump high-pressure water that will allow the cold liquid to absorb some heat, before pumping it again.
Mr. Wilcox told journalist Brian Walsh in his latest book “Times Times” that the plan could cost 3.5 billion dollars (2.9 billion pounds) and would have the added benefit of using steam from a mixture of water and magma to create carbon-free thermal electricity at a much cheaper price than Any alternative energy is currently available on the market.
Mr Willcox told Mr Walsh: “The thing that makes Yellowstone a force of nature is that it stores heat for hundreds of thousands of years before everything becomes detachable in one go. It would be nice if we dried that heat before it caused a lot of damage.”
But others are not convinced of the usefulness of Mr. Wilcox’s idea.
USGS scientist Jake Loewenstein told Mr Walsh: “It all sounds a little fictional.”
