NASA said on Tuesday that there is no evidence of a massive supervolcano erupting in 2012, despite what some may believe.
A 3-D model of a volcanic explosion, based on the 1980 eruption of Mount St Helens in Washington state, may enhance our understanding of how some volcanic explosions occur and help identify of blast zones for potentially dangerous locations.
When Mount St Helens blew its top in 1980, it wasn't a surprise that it happened, but even today the extent of the damage is hard to fathom.

New Scripps study of low-frequency sound from Mount St. Helens and Tungurahua volcanoes provides explanation for how the large-amplitude signals from eruptions are produced.
Socompa is a complex stratovolcano that can be found at the border of Chile and Argentina, reaching an elevation of 19,852 feet. This volcano is best known for its avalanche debris deposit, which have formed the Monturaqui Basin on its west side, the most noted example of this type of deposit in the world. It is a difficult volcano to visit, taking at least a day by vehicle traveling from the north or the west. Socompa is also known for the microbial ecosystems that occur near grasses at its...
