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

Tsunami Records Show Increased Hazards for Chile’s Central Coast

Sarah Stanley, Freelance Writer

From Eos.org: Research Spotlights— Simulations of the historical quake raise new concerns: A similar event in the future could cause a devastating tsunami in Chile’s most populated coastal region.  In the early morning of 8 July 1730, residents of central coastal Chile felt what would later be known.... more

Strengthening the hypothesis of a diffusion creep Earth

Editor’s Highlight—   This research field has suffered from bimodal views for the last 40 years. On the one hand there was dislocation creep, inducing crystallographic preferred orientation (CPO), and seismic anisotropy; on the other hand was diffusion creep, no CPO, and no seismic anisotropy. This.... more

The role of nickel in heat flow in the Earth’s core

Editor’s Highlight—   Understanding the physics that determines pressure-dependent electrical and thermal conductivity in metals is important for understanding the nature of the geodynamo, and its connection with the entire thermal budget of the Earth. This experimental study provides a robust demonstration.... more

Exploring hypotheses for thick crust under the Illinois Basin

Editor’s Highlight—   This paper presents a receiver function study of crustal thickness variations across the Illinois Basin and beyond using a high-density seismic array funded through EarthScope. This detailed look shows thicker crust and larger variations than previously recognized. The authors.... more
