Yellowstone volcano eruption: 191 quakes hit in month – Is supervolcano ‘recharging’?

Yellowstone national park was rocked by a staggering 191 earthquakes in the past 28 days – an average of almost seven per day. The earthquakes were relatively small, with the strongest being a magnitude 2.9 quake which hit on October 16. While tremors in the Yellowstone region are not uncommon, almost 200 in one month is rare, with the National Park Service stating that the region usually has around 700 a year.

Although on the upper scale it can have up to 3,000 quakes in a year.

Now, the unusual amount of tremors is causing panic in some quarters, with people fearing that it could blow.

One person, who just gave the name Adam, wrote on Twitter: “Yellowstone Earthquakes continues, the ‘Supervolcano’ is recharging for the next eruption”.

Another Twitter user, Tofiq Makda, added: “Immensely powerful Yellowstone super volcanic park may blast in near future.”

Indeed some geologists do believe a series of tremors can be a precursor for a volcanic eruption.

Portland State University Geology Professor Emeritus Scott Burns has said: “If you get swarms under a working volcano, the working hypothesis is that magma is moving up underneath there.”

However, others disagree about whether an earthquake swarm near a volcano could be a sign of things to come.

Jamie Farrell at the University of Utah in Salt Lake City, believes this is just part of the natural cycle for Yellowstone volcano, saying: “Earthquake swarms are fairly common in Yellowstone.

However, experts are preparing for the worst now, and are studying how a major eruption, which could instantly wipe out large swathes of the US, could be prevented.

One NASA employee believes he has found a unique way to stop a major eruption – by feeding cold water into Yellowstone’s magma chambers.

NASA engineer Brian Wilcox hopes to stave off the threat of a super-eruption is to cool down the magma in the chambers inside the volcano.

Around 60 to 70 percent of the heat generated by Yellowstone seeps into the atmosphere, but the remainder builds up inside. If enough builds up, it can trigger an eruption.

By drilling 10 kilometres into Yellowstone, the NASA employee believes that it would be possible to pump high-pressure water which will allow the cool liquid to absorb some of the heat, before it is pumped out again.

Mr Wilcox told journalist Bryan Walsh in the latter’s new book End Times that the plan could cost $3.5bn (£2.9bn) and would have the added benefit of using the steam from the water and magma combo to create carbon-free geothermal electricity at a much cheaper rate than any alternative energy currently available on the market.

Mr Wilcox told Mr Walsh: “The thing that makes Yellowstone a force of nature is that it stores up heat for hundreds of thousands of years before it all goes kablooey all at once. It would be good if we drained away that heat before it could do a lot of damage.”

Others, however, are not so convinced about the feasibility of Mr Wilcox’s idea.

USGS scientist Jake Lowenstern told Mr Walsh: “It all seems a bit fanciful.”
