Uturuncu, or Uturunku, the highest summit in southwestern Bolivia, is a stratovolcano. 6008 m asl or19,711 feet
The volcano produced lava between 890,000 and 271,000 years ago, with younger lavas found at higher altitudes.
There are clusters of active fumarole near the summit.
Researchers have determined that a large, roughly circular "disc" of land surrounding the volcano, approximately 70 km across, has been rising at a rate of 1 to 2 cm per year since at least since the early 1990s, making it "one of the fastest uplifting volcanic areas on the Earth".
Like Mount St Helens in Washington, Uturuncu is classed as a 'stratovolcano'.
But its growth could indicate it may be turning into a 'supervolcano'

According to an aerican researchteam, magma is rising in Uturuncu volcano that last erupted 300,000 years ago,
The magma is uplifting rapidly, but right now there might not be an imminent eruption.
Uturuncu was thought to be inactive. The region is populated by 'supervolcanoes'
that erupted between 1 (million)
The area at Uturuncu has had hundreds of shallow earthquakes per
year, but the rate of earthquakes increased
