Explosive Volcanic Eruption Powered by Water-Saturated Magma

Katherine Kornei, Science Writer by Katherine Kornei 26 September 201913 January 2023

Little seismic unrest preceded the 2014 eruption of a stratovolcano in Indonesia, which suggests that the eruption was kick-started internally by volatile-triggered overpressure.

How Volcanic Mountains Cool the Climate

Laura Poppick, freelance science writer by L. Poppick 13 September 20197 October 2021

Though coastal plutons spew greenhouse gases into the atmosphere as they form, they also pull some of those gases back out of the atmosphere as they break down over time.

Volcanic Eruption Creates Temporary Islands of Pumice

Katherine Kornei, Science Writer by Katherine Kornei 6 September 201918 January 2022

Rafts of pumice, spewed from an undersea volcano, recently appeared in the South Pacific. These transient, movable islands are important toeholds for marine life like barnacles, coral, and macroalgae.
