Geologists: Small magma chambers are key cause of rare and apocalyptic ‘super eruptions’

They rank among the most catastrophic natural disasters on Earth, second only in destructive power to an asteroid impact that could mean we meet the same fate as the dinosaurs. Super eruptions make those from normal volcanoes look like sputters of dust. They blast enough material into the air to…

Subterranean ‘highway from hell’ shows some volcanoes have a short fuse

A subterranean “highway from hell” enables some volcanoes to erupt at super-speed, a discovery that also throws up options for predicting the peril, according to a study published in Nature on Wednesday. Volcanoes disgorge molten rock generated within the mantle, the layer sandwiched between Earth’s crust and fiery core. The…
