Glass formed by volcanic lightning could be used to study eruptions

Blog— Researchers who study volcanoes must get creative: The extreme conditions of an erupting volcano can destroy instruments used to measure the fiery event, making studying the heat, energy, lava flow, and other characteristics of the eruption difficult. Now, researchers have developed a method to.... more

Catching Glimpses of Centuries-Old Earthquakes

Sarah Witman, Freelance Writer

From Research Spotlights— Researchers in the western United States survey the earthquakes that have torn up California for the last millennium. Seismologists are not known for their subtlety. So it should come as no surprise that a genre of quakes characterized by the way they wrench apart.... more

Diagnosing Cryptic Remagnetization in Sedimentary Rocks

Terri Cook, Freelance Writer

From Research Spotlights— To understand ancient movements of Earth’s tectonic plates, comprehensive magnetic and petrographic studies are needed to detect secondary magnetization in carbonates and other sedimentary rocks.  After being exposed to Earth’s magnetic field, some minerals within.... more

What Causes Rock Avalanches?

Terri Cook, Freelance Writer

From Research Spotlights— Experimental studies of frictional weakening beneath a deadly rock avalanche in China help to clarify the mechanisms that cause these devastating natural disasters.  Rock avalanches, sudden rock slope failures characterized by very rapid velocities, long runouts,.... more

Hydrolytic weakening in olivine single crystals

Editors’ Highlight—  The authors present a set of experiments to investigate the role of hydrolytic weakening in olivine single crystals. The key result is that during experimental deformation of olivine at high PT conditions, the dominant deformation mechanism switches from rate limiting pipe diffusion.... more

An Improved Model of How Magma Moves Through the Crust

Terri Cook, Freelance Writer

From Research Spotlights— 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.  Volcanic eruptions of basalt are fed by intrusions of magma, called dikes, which advance through Earth’s crust for a few hours.... more

Geometry and evolution of a fault-controlled Quaternary basin by means of TDEM and single-station ambient vibration surveys: the example of the 2009 L’Aquila earthquake area

Editors’ Highlight—This paper presents the results of seismic geophysical surveys in the area of central Italy where the 2009 L’Aquila earthquake caused considerable damage. The data provide new insight into the 3D shape of the basin and has uncovered some potential new faults whose activity should.... more
