Is She About To Blow? Scientists Investigate
Riddle of Rapidly Inflating Volcano
Daily

A previously
dormant South American volcano is inflating with astonishing speed,
scientists have discovered.
Researchers
from several U.S. universities say Uturuncu, which rises 6,000 meters
in southwest Bolivia, is blowing up like a big balloon as its magma
chamber grows around 10 times faster than normal.
'It's one of
the fastest uplifting volcanic areas on Earth,' said Oregon State
University professor, Shan de Silva.
Waking
up: Uturuncu, which rises 6,000 meters in southwest Bolivia, is
blowing up like a big balloon, according to scientists
'What we're
trying to do is understand why there is this rapid inflation, and
from there we'll try to understand what it's going to lead to,'
said de Silva in an interview with MyAmazingPlanet.
Uturuncu is
classed as a 'stratovolcano' - the most common type. But there is
some concern that its rapid growth could indicate that a supervolcano
is on its way.
A supervolcano
erupts with such power that it can shoot out 1,000 times more material
than a stratovolcano like Uturuncu or Mount St Helens in Washington.
It can also have a devastating global effect.
Like Mount
St Helens in Washington, Uturuncu is classed as a 'stratovolcano'.
But its growth could indicate it may be turning into a 'supervolcano'
Modern man
has never witnessed such an event. The last supervolcanic eruption
occurred around 74,000 years ago in Indonesia.
However, the
researchers looking at Uturuncu are quietly confident there is nothing
to worry about.
'It's not a
volcano that we think is going to erupt at any moment, but it certainly
is interesting, because the area was thought to be essentially dead,
professor de Silva said.
Stratovolcanoes
are conical shaped and deliver periodic, explosive eruptions

The Yellowstone
Caldera in the U.S. is classed as a supervolcano, a type that can
erupt 1,000 times more material than a stratovolcano
