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

Can Water Vapor Help Forecast When a Volcano Will Blow?

Emily Underwood, Freelance Writer

From Eos.org: Research Spotlights— A widely used technique to monitor sulfur dioxide was tweaked to focus on water vapor at Peru’s Sabancaya Volcano. Results show that the volcano steamed up prior to its 2016 eruption.  The magma that bursts out of volcanoes is propelled upward largely by dissolved.... more

Nonlinear elasticity placed in the context of frictional models

Editor’s Highlight—   This paper describes torsional oscillator observations in rock samples under load that have been fractured and mated. A theoretical slider block-type model describes the experimental observations in order to relate the nonlinear response to rate-dependent model, a version of the.... more

Toward an understanding of mass transfers across the mantle transition zone

Editor’s Highlight—   A low-velocity zone atop the 410-km discontinuity (410) could potentially explain the preservation of enriched geochemical reservoirs in the mantle and is of importance for our understanding of mass transfers across the transition zone. The main limitations of seismic studies for.... more

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
