A team of researchers affiliated with a host of institutions in France has recorded the details and characteristics of an undersea volcano that was born in 2018. In their paper published in the journal Nature Geoscience, ...
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 ...

A team of researchers from the Istituto Nazionale di Geofisica e Vulcanologia, in Italy, has found evidence showing that magma pressure had begun building up deep in Mt. Etna's reservoir several months before the 2018 eruption. ...
Currently, much of the thinking around risks posed by volcanoes follows a simple equation: the bigger the likely eruption, the worse it will be for society and human welfare.
