Yellowstone Volcano: How Geologists Observed Earthquake SWARM & # 39; | Science | News



Yellowstone Volcano erupted three times in history – 2.1 million years ago, 1.3 million years ago and 630,000 years ago. Jacob Lowenstein of the United States Geological Survey (USGS) lifted the lid on the first geological exploration of Yellowstone National Park. During their stay, the group experienced an earthquake swarm that shook the trees and earth beneath them.

In 1871, Ferdinand Vanderveer Hayden led a team of 50 keen geologists on the first exploration of the Yellowstone volcano.

Mr. Lowenstein revealed how the team gathered information about the super volcano.

He said in 201

4: "Ferdinand Hayden was one of the people who drove the expedition that went through Yellowstone.

" This was the group that ultimately got the US geological survey started about ten years later.

They saw what we now call an earthquake swarm

19659012] "Hayden brought with William Henry Jackson – a photographer – and Thomas Moran – a painter.

"D e collect d samples, they documented what they saw, and they did it both through photography and paintings.

"They were sent back to Washington and were instrumental in having Congress set aside Yellowstone as a national park."

Mr Lowenstein also revealed how Mr Hayden realized it was a volcanic area.

He added: "He acknowledged that it was a volcanic area, and he knew it was not too far in the geological past that it was active.

"He put it slightly older than it really is and he also acknowledged that The hot springs and water were related to the volcanic system.

"He and his colleagues camped on the northern side of Yellowstone Lake and they experienced another remarkable thing we know about Yellowstone – there are many earthquakes.

"They saw what we now call an earthquake swarm where they were awakened in the middle of the night by a series of shakes that shook the trees."

Revelation comes after Mr Lowenstein's colleague and scientist-in -charge Mike Poland sent a warning about a plan by NASA.

The space organization came up with a concept to drill into the hydrothermal system and cool the volcano.

The idea apparently could "save the world" and cost about $ 2.7 billion.

But Poland did not revoke it.

He said in 2018: "There are no plans to actually do this, it was just a plan in the concept.

" But there are no plans to do some drilling in Yellowstone and I can't imagine that it would ever be allowed as it is a national park.

"It wouldn't have the intended effect either – it's not even a good idea."

Poland continued to claim drilling could also destroy Yellowstone's natural beauty. [19659003] He added: "It would have the potential disadvantages of influencing all the natural features of Yellowstone.

"In other parts of the world where geothermal wells have been drilled near geysers, it has actually subdued the activity altogether.

" So it's unlikely to happen. "

Con cerns have grown recently over the potential that Yellowstone could break out again from the public.

However, Poland closed these claims during a weekly update from USGS.

The scientist said: "We have heard many statements that Yellowstone is delayed – that it has a major outbreak every 600,000 years on average, and Since the last outbreak was 631.000 years ago, you can see where it goes.

"Is it true? In a word, no. In two words, no way. In three words, not even close. Yellowstone does not work that way."

Calculating that Yellowstone erupted about every 600,000 years , has made many claim that supervolcano is "delayed".

Dr. Poland, however, argued for vol canoes ] do not behave this way and as a result there are no indicators Yellowstone is obliged to break out again.

The researcher explained: "This comes to an average of about 725,000 years between outbreaks.

" It is true that we still have about 100,000 years to go, but this figure is based on very small data and is basically pointless – will you base any conclusion on average on only two numbers? "

" The point, however, is that if someone, or an article or documentary, says that Yellowstone eruptions every 600,000 years, you know right from bat that they are full of baloney. "
