Tracking Volcanic Bombs in Three Dimensions
A new method allows researchers to precisely track in three dimensions bits of fragmented magma as they are expelled in explosive volcanic eruptions.
Pulses of Rising Magma in Sierra Nevada's Past
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.
Pinpointing the Trigger Behind Yellowstone's Last Supereruption
Geologists suggest that mixing of magma melt pockets could have caused the explosion a little more than 600,000 years ago.
Scientists Offer New Explanation for Island's Unexpected Uplift
Researchers developed a new timeline for the rise, fall, and rise again of a puzzling island in the Azores.
A Better Model for How the Mantle Melts
A new model of the melting behavior of certain mantle rocks gives researchers a better understanding of the source of oceanic lavas.
We Need a New Definition for “Magma”
Confusion over the meaning of "magma" can generate popular misperceptions, including a nonexistent molten sea underneath Yellowstone National Park. We propose a different definition.
New Insights into North America’s Midcontinent Rift
The Midcontinent Rift has characteristics of a large igneous province, causing geologists to rethink some long-standing assumptions about how this giant feature formed.
Eyjafjallajökull Gave Lava and Ice Researchers an Eyeful
New insights from the 2010 eruption may help volcanologists determine how glaciers shaped ancient lava flows.
Does Geothermal Exploitation Trigger Earthquakes in Tuscany?
For the past 25 years, power production has been accompanied by a small but steady increase in seismicity near geothermal wells. A new project seeks to explore why.
