Massive 'lake' discovered under South American volcano that could unlock why and how volcanoes erupt

Scientists from the University of Bristol and partner universities in Germany, France, Canada and Wales, have discovered a huge magmatic lake, 15 kilometres below a dormant volcano in Bolivia, South America.
The body of water - which is dissolved into partially molten rock at a temperature of almost 1,000 degrees Celsius - is the equivalent to what is found in some of the world's giant freshwater lakes, such as Lake Superior.

Huge lake discovered 15 kilometres under a volcano

Jon Blundy of the University of Bristol, UK, and his colleagues made the discovery while studying a huge "anomaly" 15 kilometres beneath the currently dormant Uturuncu volcano in the Bolivian Andes. The anomaly, called the Altiplano-Puna magma body, slows down seismic waves and conducts electricity, unlike surrounding magma.
Blundys team took rocks that were spat out by an eruption of Uturuncu 500,000 years ago and mixed them with varying amounts of water before exposing them in the lab to conditions mimicking those in the anomaly.

Scientists study world's fastest-growing volcano to find out what causes deadly eruptions

With the last eruption exploding from a supervolcano occurring 74,000 years ago, it is perhaps understandable that scientists don't fully understand how they work.
But that could all be about to change thanks to a team of experts in Bolivia.
An international group of scientists are studying the country's Uturuncu, which is the world's fastest-inflating volcano.
And by studying the volcano, more light is being shed on how supervolcanoes became so powerful.

Uturuncu is a nearly 6,000 meter-high volcano in southwest Bolivia. Scientists recently discovered the volcano is inflating with astonishing speed.
Researchers realised about five years ago that the area below and around Uturuncu is steadily rising - blowing up like a giant balloon under a wide disc of land some 70 kilometres across. Satellite data revealed the region was inflating by 1 to 2 centimetres per year and had been doing so for at least 20 years, when satellite observations began.

Uturuncu, or Uturunku, the highest summit in southwestern Bolivia, is a stratovolcano. It displays young well-preserved lava flows at its summit which were erupted during the Pleistocene period. The volcano also shows fumarolic activity.
