People Need to Think Bigger About Volcanic Catastrophes
New research outlines the risk of catastrophic eruptions and urges policymakers to support more widespread monitoring.
Supervolcanoes Linger a While, Then Rush to Erupt
Geologists examined crystals in rock from four massive eruptions in the Chilean Andes.
Global Seismic Networks: Recording the Heartbeat of the Earth
Global broadband seismographic networks have provided the science community with 30 years of data which is being used to understand the Earth.
Old Igneous Rocks Hold the Key to Crustal Thickness Evolution
The chemical composition of orogenic igneous rocks and their zircons is sensitive to crustal thickness and can be used to quantify the evolution of Moho depths beneath continents back in time.
Volcanic Winters Ushered in the Jurassic Reign of the Dinosaurs
Sediment cores from northwestern China reveal freezing conditions during the Late Triassic killed off many forms of life—but not dinosaurs.
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.
Tonga Volcanic Eruption Produced Ionospheric Hole and ‘Bubbles’
The 2022 Tonga volcano eruption altered the global ionosphere, creating a huge ionospheric hole locally near the epicenter and large-amplitude plasma bubbles remotely over the Asia-Oceania area.
A Spike in Wildfires Contributed to the End-Permian Extinction
An upward trend in fossilized charcoal indicates that wildfires may have contributed to extinctions during the Great Dying.
