New Computer Model Predicts Impact of Yellowstone Volcano Eruption 121
An anonymous reader writes Scientists from the U.S. Geological Survey (USGS) have used a program named Ash 3D to predict the impact of a Yellowstone volcano eruption, and found that cities within 300 miles from Yellowstone National Park may get covered by up to three feet of ash. From the article: "Ash3D helped the researchers understand how the previous eruptions created a widespread distribution of ash in places in the park's periphery. Aside from probing ash-distribution patterns, the Ash3D can also be used to identify potential hazards that volcanoes in Alaska may bring."

Wow ... there is a lot of talk about the Yellowstone volcano. Do the authorities know more than they are saying to the public? Why all of the sudden interest in Yellowstone? Is an eruption imminent and we are not being told?

As a geologist the impact, size and risk of Yellowstone has been an ongoing learning experience.
Yellowstone like large eruptions and large asteroid impacts are global game changers.
Any that wake up in the morning and think about this get concerned.
Both issues invoke magical thinking... we could make the problem go away by -________-.
What we do know is that historic eruptions did blanket North America with ash,
we also have some decent data about how many and how often and when we
might be due...
The un-interesting bit is the mumble foo about a computer program. Some think
this is adding to the knowledge but the reality is hand drawn maps from
20 years ago tell the same OMG KYAGB story.
Add regions of Indonesia to the list right along side the Mammoth Mtn. caldera in California.
These game changing big events are well beyond any FEMA planning.
Have a good cup of tea and enjoy the fireworks.

I loved the neat 3D simulator the BBC fabricated for their docudrama Supervolcano [youtube.com]. After the run one of the geologists (played by Gary Lewis) says, "[laughing] That's great... and if frogs had wings they wouldn't bump their little green asses hoppin' around, eh? [...] You're letting yourself be spooked by a video game!"
Great TEOTWAWKI drama, decent science, I recommend it: Supervolcano Ep1 [youtube.com], Supervolcano Ep2 [youtube.com], and the companion factual documentary Supervolcano.The Truth About Yellowstone [youtube.com] which re-uses CGI footage made for the drama between interviews.
Here is a map that shows the ash coverage. (Score:5, Interesting)
