New research reveals how the presence and absence of magmatism governs how shear zones initiate, grow, and reactivate to connect lower and upper crustal deformation.

Supervolcanoes Linger a While, Then Rush to Erupt
Geologists examined crystals in rock from four massive eruptions in the Chilean Andes.
Unraveling the Mystery of a Rare Mineral on Mars
The discovery of tridymite in Mars’s Gale Crater triggered debate about the rare mineral’s origins. A research team recently suggested a scenario with explosive implications.
This One Simple Trick Helps Us Understand How Much Water Is in Martian Lavas
Understanding how much water is in Martian magma is vital for understanding whether the Red Planet had seas in its early history.
Why Do Arc Volcanoes Deform Less Than Ocean Island Volcanoes?
Volcanic ground deformation is not simply correlated with erupted volume. Researchers propose that high concentrations of magmatic volatiles make systems more compressible and suppress deformation.
A New, Fast Computational Tool for Magmatic Phase Equilibria
Thermodynamic calculations in multiphase, multicomponent magmatic systems can be slow and buggy. A new parallel architecture solves the free energy minimization problem much faster than alternatives.
Earth’s Lower Mantle Is Drier Than Previously Thought
Scientists have long known that the two layers of Earth’s mantle have different chemical compositions. Now, modeling shows that different water concentrations may keep them from mixing.
Volcanic Lava Lake Belts Out Its Secrets in Seismic “Songs”
A cacophony of magma displacements and volcanic gases recorded underneath Kīlauea’s roiling lake of lava could one day provide information to help predict future eruptions.
Dynamics of Volcanic Processes
A new cross-journal special collection invites contributions on modern approaches used to investigate dynamics of volcanic processes.
Unlocking the Magmatic Secrets of Antarctica’s Mount Erebus
Unprecedented images of Mount Erebus’s inner workings show the unique trappings of a CO2-rich rift volcano.
