Magma Lingers at Different Depths on the Basis of Its Water Content

Katherine Kornei, Science Writer by Katherine Kornei 4 April 202225 April 2022

The discovery, gleaned from observations of volcanoes on four continents, could help constrain models of volcanic eruptions.

A river of molten lava flows across a steaming black basalt landscape. The river flows from a volcanic rift near the top right of the image toward the bottom left. The fissure is filled with brighter and hotter lava and steam and gas billows up from it. The sky on the horizon is a hazy blue-gray.

The Surprising Greenhouse Gas That Caused Volcanic Summer

Kimberly M. S. Cartier, News Writing and Production Intern for Eos.org by Kimberly M. S. Cartier 21 March 202212 April 2022

Extended periods of volcanism known as flood basalt eruptions lead to volcanic winters, which are often followed by an extended period of warming. But it was more than just carbon dioxide that warmed the globe.
