3-D model mimics volcanic blast

Publication: msnbc.com   Date: June 1, 2011   View Article

A new 3-D model that realistically mimics the 1980 eruption of Mount St. Helens is helping scientists understand the dynamics of such blasts and may help them map potential blast flows at dangerous volcanoes around the world.

The eruption of the volcano in Washington killed 57 people, leveled forests and sent a torrent of mud and debris down rivers that wiped out hundreds of homes and dozens of bridges.

The damage stems from a fast-moving current of superheated gas and hot rock and debris that was blasted out sideways from the volcano, Barry Voight, an emeritus professor of geology at Penn State, explained to me today.
