Beneath Yellowstone, A Volcano That Could Wipe Out U.S.

” A team from the University of Utah have told the American Geophysical Union Fall Meeting in San Francisco that Yellowstone’s magma chamber is 2.5 times larger than previously thought.

  It is an underground cavern measuring some 55 miles by 20 miles and containing between 125 and 185 billion cubic miles of molten rock.

  If it blows it will wipe out America – and have enormous impacts on the rest of the world.

  The university researchers described their discovery as “astounding.”

  Professor Bob Smith told the BBC: “We’ve been working there for a long time, and we’ve always thought it would be bigger … but this finding is astounding.” “

 

 

 

 

 

 

 

 

New High-Speed Camera System Reveals What Snow Looks Like In Midair

” These fluffy snowflakes, known as aggregates, form when snow crystals collide with other snow crystals. Many of these flakes also show some riming, or an icy coating. A new high-speed, three-camera system developed at the University of Utah made these pictures as the snowflakes fell.  University of Utah researchers developed a high-speed camera system that spent the past two winters photographing snowflakes in 3-D as they fell – and they don’t look much like those perfect-but-rare snowflakes often seen in photos.

With help from the University of Utah’s Technology Commercialization Office, Garrett and Cale Fallgatter – a 2008 master’s graduate in mechanical engineering – formed a spinoff company, Fallgatter Technologies, to make the new camera system, known as the MASC, for Multi-Angle Snowflake Camera, for which a patent is pending.

The device – under development for three years – includes three, industrial-grade, high-speed cameras: two 1.2-megapixel cameras and a 5-megapixel camera, plus two sets of two motion sensors to measure the speed of falling snowflakes. The 5-megapixel camera helps zoom in on single flakes, Fallgatter says.

The Multi-Angle Snowflake Camera has a ring-shaped housing measuring about 1 foot wide and roughly 4 inches tall. The three cameras are mounted on one side, each separated by 36 degrees and pointed toward the center.”
