New insights in to the strength of rocks

Editor’s Highlight—   This paper presents new high-resolution analyses of dislocation microstructures in deformed single crystals. The authors apply techniques that provide new insights into dislocation interactions during viscous deformation that have the potential to significantly improve our understanding.... more

Analysis of injection-induced seismicity related to wastewater disposal

Editor’s Highlight—   This study provides a comprehensive analysis of the 2015 Mw 4.0 Venus, Texas earthquake sequence and its links to the injection of wastewater. The authors examine seismicity prior to the Mw 4.0 earthquake using a matched filter technique. They demonstrate that seismicity begins.... more

New type of guided acoustic waves revealed

Editor’s Highlight—   This paper addresses the existence and nature of waves that travel on intersections between objects arranged in three dimensions, such as fractures is a rock mass. By combining theoretical and experimental results, the authors show the existence of various modes of seismic wave.... more

Modeling the spatiotemporal variation of earthquake rates

Editor’s Highlight—   This paper investigates a time series of seismicity associated with the 2010 El Mayor-Cucapah earthquake and subsequent Octillo aftershock in the Yuha Desert, California. Dividing the affected rea in two three regions, the authors find that the seismicity rate in two regions agrees.... more

Quiet Volcanic Activity Changes Speed of Ambient Seismic Waves

Sarah Stanley, Freelance Writer

From Eos.org: Research Spotlights— Seismic data collected continuously for 4 years could improve understanding of geological structures that underlie Japan’s Izu-Oshima volcanic island.  Volcanic eruptions, earthquakes, landslides, and other events can trigger seismic waves that travel through Earth..... more

New insights into geodynamics of NE Tibetan Plateau

Editor’s Highlight—   This paper presents a new model of shear-wave velocity beneath the Northeast Tibetan Plateau, Ordos Basin and surrounding areas based on joint inversion of receiver functions and constraints from existing Rayleigh wave tomography. The model is valuable because the station density.... more

Comparing earthquake spectra

Editor’s Highlight—   In seismology, we do not know whether the earthquake source is best represented as an expanding crack or a propagating pulse. Perhaps neither is the actual representation when the faulting is heterogeneous. However, the literature generally separates into the two mentioned models.... more

A Promising New Tool for Forecasting Volcanic Hazards

Terri Cook, Freelance Writer

From Eos.org: Research Spotlights— A new model that simulates the behavior of surging ash clouds may help scientists to better predict the hazards associated with the deadliest type of volcanic flows.  The deadliest and most destructive phenomena associated with volcanoes are pyroclastic flows, fluidlike.... more

Factors that influence the presence of hot crater lakes at active volcanos

Editor’s Highlight—   This paper proposes a new physical model of volcanic crater lakes, examines the sustainability of their temperature and level, and then applies this model to some recent observations of crater lakes. They find that high temperature lakes without sealed bottoms are sustainable,.... more

A coupled deformation-devolatilisation model

Editor’s Highlight—   This paper considers the mechanisms by which dehydrating mineral reactions are coupled to deformation to induce mechanical instabilities. The authors develop an isothermal “porosity-softening” coupled deformation-devolatilisation model. This leads to instabilities in the form of.... more
