Researchers test whether the changing composition of volcanic gas can signal a coming eruption in Chile’s Villarrica volcano.
An international seismological collaboration in Kamchatka, Russia, investigates the driving forces of one of the world’s largest, most active volcano clusters.
Researchers have developed a new numerical model that can, for the first time, solve for both the speed and the path of a propagating dike.
These peculiar features of submarine volcanic eruptions could be the result of undersea lava lakes.
A new method allows researchers to precisely track in three dimensions bits of fragmented magma as they are expelled in explosive volcanic eruptions.
A detailed study of layered igneous material at California's Fisher Lake offers a novel approach to identifying the pathways and timescales of individual magma pulses in volcanic arcs.
Geologists suggest that mixing of magma melt pockets could have caused the explosion a little more than 600,000 years ago.
Researchers developed a new timeline for the rise, fall, and rise again of a puzzling island in the Azores.
A new model of the melting behavior of certain mantle rocks gives researchers a better understanding of the source of oceanic lavas.
Confusion over the meaning of "magma" can generate popular misperceptions, including a nonexistent molten sea underneath Yellowstone National Park. We propose a different definition.
