Wonderfully clear and sensible statement about the Yellowstone volcano

Comments Off on Wonderfully clear and sensible statement about the Yellowstone volcano

Thanks to the USGS and probably attributable to Jacob Lowenstern, this month we have a new statement from some of the world’s best authorities on the so-called Yellowstone supervolcano. They call it Five Things Most People Get Wrong About the Yellowstone Volcano, going at the problem of media sensationalism from the back side.

Lowenstern is Scientist-in-Charge of the Yellowstone Volcano Observatory and studies magma and volcanic phenomena in Yellowstone and all over the world for the United States Geological Survey, Menlo Park, CA.

The misconceptions this article lists are:

  • When Yellowstone erupts it will be Armageddon
  • The Yellowstone magma chamber is growing
  • Yellowstone is overdue for a supereruption
  • Yellowstone is rapidly rising
  • Earthquake data indicates moving magma.

All this is well worth absorbing and passing on to any worrywarts you know! And if you want to read more of the “true facts” (what are false facts?) about supervolcanoes, the Volcano Observatory has recently updated another great page by the world’s best authorities on the subject.

Terrorists and Supervolcanoes

Comments Off on Terrorists and Supervolcanoes

Generally, I prefer to steer clear of the media flurry every time there’s a large swarm of earthquakes or something else in the news that again brings up the subject of the Yellowstone supervolcano. But I can’t resist passing on this reaction to the recent news about a terrorist in Canada thinking that triggering the magma under Yellowstone would be a great idea.

At least the article about this that I just found ends with a sensible paragraph:

“Fortunately, the USGS agrees the likelihood of a Yellowstone volcano eruption is unlikely at this time. The volcano alert level is currently green, and seismographs detected only 178 earthquakes in the region, with the largest registering at a magnitude 1.9 on January 20, 2015. The USGS also calculates the odds against a Yellowstone eruption as 730,000 to one on an annual basis. As a comparison, the odds of a royal flush in poker is 1 in 649,740, so perhaps that’s not too comforting.”

For the best current information on the subject see this USGS page, or take a look at our own nugget about it.

Just to let you know: Yesterday Jake Lowenstern and colleagues at the USGS/Yellowstone Volcano Observatory issued a very clear and detailed explanation of just what the new research on the magma system shows and how it was obtained. To read it, you need to scroll down under the map on the YVO website:
