Distant earthquakes can cause underwater landslides

Press Release— New research finds large earthquakes can trigger underwater landslides thousands of miles away, weeks or months after the quake occurs. Researchers analyzing data from ocean bottom seismometers off the Washington-Oregon coast tied a series of underwater landslides on the Cascadia Subduction.... more

A 667-year record of co-seismic and interseismic Coulomb stress changes in central Italy reveals the role of fault interaction in controlling irregular earthquake recurrence intervals

Editors’ Highlights—   This paper considers the important topic of how large earthquakes interact over multiple seismic cycles. Building on a comprehensive paleoseismic catalogue of historical earthquakes in central Italy and a model of the geometry of faults located there, this study looks at the stress.... more

Lab Experiments Show How Fault Surfaces Get Groovy

Sarah Stanley, Freelance Writer

From Eos.org: Research Spotlights— Formation of nanometer-scale quartz beads could promote linear “slickenline” patterns and facilitate fault movement.  Linear patterns known as slickenlines streak the surfaces of many faults around the world. These smooth, polished features consist of tiny ridges.... more

Magma reservoir study on melt content and magma distribution

Editors' Highlight—   This quantitative study compares melt content of off-axis melt lenses with the on-axis melt lens at the East Pacific Rise. These features were only recently recognized, and their importance is still being investigated. The authors use high resolution 3D multichannel seismic data,.... more

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
