Huge water-magma lake found 15 km below Bolivian volcano
An international team of researchers has discovered a lake, containing 10% water and rest partially molten rock at temperatures of almost 1,000ºC, 15 km below a Bolivian volcano. When the pressure falls in the liquid body, the water comes out, forming bubbles and driving volcanic eruptions. The team claimed that the find could help explain why and how volcanoes erupt.
