How to better identify dangerous volcanoes
How to better identify dangerous volcanoes
The more water is dissolved in the magma, the greater the risk that a volcano will explode. A new ETH study now shows that this simple rule is only partially true. Paradoxically, high water content significantly reduces the risk of explosion. Volcanologists have long been troubled by two questions: When exactly will a volcano erupt next?
