Scientists Create Catalog of Altotiberina Fault in Italy

David Shultz, Freelance Writer

Research Spotlight— More than 37,000 small earthquakes paint a picture of the fault’s behavior and seismic potential. The Apennine Mountains dominate the Italian peninsula, spanning 1,200 kilometers and reaching peaks as high as 2,912 meters. In the northern part of the range lies the Altotiberina fault,.... more

New Thermodynamic Model for Computing Mantle Mineralogy

Michael Walter, Editor, JGR: Solid Earth

Editors' Highlight— A newly developed open-access software package called MMA-EoS can calculate whole mantle mineralogy in multicomponent systems by Gibbs energy minimization. Understanding the tectonic processes that shape the surface of our planet requires knowledge of the inner workings of its deep.... more

Using Radar to Understand How Volcanic Eruptions Evolve

Terri Cook, Freelance Writer

Research Spotlight— Radar satellite imagery can be used to measure constructional changes in the topography of long-lived volcanoes, according to a new study of Ecuador’s El Reventador volcano. The rate at which a volcano extrudes lava is a key variable for tracking changes in volcano behavior, magma.... more

Testing a New Tool That Illuminates Tiny Fractures in Coal

Sarah Stanley, Freelance Writer

Research Spotlight— A computational model outperforms a widely used microcomputed tomography imaging method in characterizing coal fractures. Tiny micrometer-scale fractures, or “cleats,” permeate coal beds and create networks that often harbor a form of natural gas known as coal seam gas. Coal seam.... more

What Feeds Indonesia’s Destructive Mud Eruption?

Sarah Stanley, Freelance Writer

Research Spotlight— New advances in seismic investigations suggest links in plumbing between nearby magma volcanoes and a mud-erupting system that has been spewing for more than a decade. On 29 May 2006, a mud eruption in East Java in Indonesia burst through the ground. It spewed enough hot, steaming.... more

The Curious Case of the Ultradeep 2015 Ogasawara Earthquake

Terri Cook, Freelance Writer

Research Spotlight— Unusual ground motion associated with the deepest major earthquake in the seismological record is due to both its great depth and its origin away from the subducting slab. On 30 May 2015, a powerful earthquake struck west of Japan’s remote Ogasawara (Bonin) island chain, which lies.... more

Explaining seafloor tsunami magnetic signals

Editor’s Highlight—   This paper provides the latest installment in the improved numerical modeling and diagnostic interpretation of tsunami-generated magnetic fields. The authors present a powerful new simulation method and apply it to the 2011 Tohoku tsunami event, revealing the spatiotemporal properties.... more

Understanding the kinematic rupture process of the Kumamoto earthquake

Editor’s Highlight—   Using GPS, strong motion, Synthetic Aperture Radar images and surface offset data, this paper seeks to understand the kinematic rupture process of the 2016 Kumamoto earthquake. The authors use a joint inversion to resolve the kinematic rupture process of the mainshock and co-seismic.... more

New microscopic model of rate-and-state dependent friction laws

Editor’s Highlight—   The rate-and-state friction law is empirical, and has different versions (aging vs slip laws). Since the physics underlying rate-and-state friction is not well understood, as is the choice between its versions, there is a need to find a physics-based model that captures it. This.... more

Flow laws for quartz dislocation creep

Editor’s Highlight—   This paper rationalizes the wide range of experimental data for plastic deformation of quartz, and shows that studies with apparently quite different results can be reconciled with theoretical flow laws by incorporating a water fugacity term in the experimentally determined flow.... more
