Study of historic Chilean quake warns of a future tsunami

Blog— The most populated central region of Chile could be vulnerable to large tsunamis generated by a deceptively moderate kind of earthquake that might be overdue, say scientists who have sorted out the source of an earthquake and tsunami that struck the area 287 years ago. The region is the same that.... more

Image log analysis of in-situ stress orientation, breakout growth, and natural geologic structures to 2.5 km depth in central Scandinavian Caledonides: Results from the COSC-1 borehole

Editors' Highlight—    This paper presents a detailed description of the stress-induced structures observed with acoustic imaging in a deep borehole in western Sweden, an area where few measurements of this sort have previously been made. The occurrence of breakouts and foliation data are used to constrain.... more

Frictional Strength of Wet and Dry Montmorillonite

Editors’ Highlight— Montmorillonite may dramatically weaken shallow fault zones (it is not stable above 80 degree Celsius), but numerous previous experiments revealed very diverse and complex frictional behaviors of this mineral. This paper reports results of carefully conducted friction experiments.... more

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
