It is estimated that about 5 to 10 volcanoes worldwide are capable of producing a super-eruption that could catastrophically affect global climate. One of these volcanoes hides below the waters of Lake Toba in Sumatra and ...

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. ...
Shortly after it formed, the moon was covered in a global ocean of molten rock (magma). As the magma ocean cooled and solidified, dense minerals sank to form the mantle layer, while less-dense minerals floated to form the ...

There are some large shield volcanoes in the world's oceans where the lava is usually not ejected from the crater in violent explosions, but flows slowly out of the ground from long fissures. In the recent eruption of the ...
