Researchers from several universities trying to unravel the mystery of South American volcano to swell rapidly. Using various tools to calculate the peak of the mountain that continues to grow, they want to understand what is happening now and the future.

Uturuncu is 6.000-meter-high volcano in southwestern Bolivia. In contrast to other volcanoes, Uturuncu enlarged with remarkable speed.
"I call 'forensic volcano' because we use so many different techniques to understand this phenomenon," said Shan de Silva, an expert volcanologist research team from Oregon State University in Corvallis, United States.
The scientists began to realize that the area under and around Uturuncu continues to grow, swell up like a giant balloon at 70 kilometers in diameter underground. Satellite data reveal that the area to swell 1-2 centimeters per year for 20 years.

Interferograms (draped over shaded relief) indicate active deformation; each color cycle corresponds to 5 cm of deformation in the radar line-of-sight (LOS). The LOS direction from ground to spacecraft (black arrow) is inclined 23° from the vertical. Black squares indicate radar frames, and black triangles show potential volcanic edifices.

"It is a volcanic area of the fastest rising in the earth," said De Silva. "We're trying to understand why it happened fast swelling, and predict how the mountain in the future."
Top of the mountain-perched like a party hat in the center of the swollen area. "The shape is very round," said Jonathan Perkins, researchers from the University of California.
From the speed Uturuncu bubbles, scientists estimate the magma chamber beneath the mountain was growing at about 1 cubic meter per second. "That's about 10 times faster than the growth rate of the magma chamber standards for major mountain system," said Perkins. *** [LIVESCIENCE | KORAN TEMPO 3688]
