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.
The Midcontinent Rift has characteristics of a large igneous province, causing geologists to rethink some long-standing assumptions about how this giant feature formed.
New insights from the 2010 eruption may help volcanologists determine how glaciers shaped ancient lava flows.
