Using advanced technology that analyzes tiny gas bubbles trapped in crystal, a team of scientists has precisely mapped how magma storage evolves as Hawaiian volcanoes age. Using advanced technology ...

Models that inform how magma moves and volcanic eruptions unfold may need an update, according to a new study. It reports that gas bubbles in magmas can form through the mechanical forces of shear as ...

The explosiveness of a volcanic eruption depends on how many gas bubbles form in the magma—and when. Until now, it was thought that gas bubbles were formed primarily when the ambient pressure dropped ...

Scientists have uncovered a long-missing piece of the volcanic puzzle: rising magma doesn’t just form explosive gas bubbles when pressure drops—it can do so simply by being sheared and “kneaded” ...

Using advanced technology that analyzes tiny gas bubbles trapped in crystals, a team of scientists led by Cornell University has precisely mapped how magma storage evolves as Hawaiian volcanoes age.

Forbes contributors publish independent expert analyses and insights. David Bressan is a geologist who covers curiosities about Earth. How and if a volcano explodes depends on how and when bubbles of ...
