DOWNLOAD EBOOKSubduction dynamics has been actively studied through seismology, mineral physics, and laboratory and numerical experiments. Understanding the dynamics of the subducting slab is critical to a better understanding of the primary societally relevant natural hazards emerging from our planetary interior, the megathrust earthquakes and consequent tsunamis. Subduction Dynamics is the result of a meeting that was held between August 19 and 22, 2012 on Jeju island, South Korea, where about fifty researchers from East Asia, North America and Europe met. Chapters treat diverse topics ranging from the response of the ionosphere to earthquake and tsunamis, to the origin of mid-continental volcanism thousands kilometers distant from the subduction zone, from the mysterious deep earthquakes triggered in the interior of the descending slabs, to the detailed pattern of accretionary wedges in convergent zones, from the induced mantle flow in the deep mantle, to the nature of the paradigms of earthquake occurrence, showing that all of them ultimately are due to the subduction process. Volume highlights include: Multidisciplinary research involving geology, mineral physics, geophysics and geodynamics Extremely large-scale numerical models with sliate-of-the art high performance computing facilities Overview of exceptional three-dimensional dynamic representation of the evolution of the Earth interiors and of the earthquake and subsequent tsunami dynamics Global risk assessment strategies in predicting natural disasters This volume is a valuable contribution in earth and environmental sciences that will assist with understanding the mechanisms behind plate tectonics and predicting and mitigating future natural hazards like earthquakes, volcanoes and tsunamis.

DOWNLOAD EBOOKSubduction is a major process that plays a first-order role in the dynamics of the Earth. The sinking of cold lithosphere into the mantle is thought by many authors to be the most important source of energy for plates driving forces. It also deeply modifies the thermal and chemical structure of the mantle, producing arc volcanism and is responsible for the release of most of the seismic energy on Earth. There has been considerable achievements done during the past decades regarding the complex interactions between the various processes acting in subduction zones. This volume contains a collection of contributions that were presented in June 2007 in Montpellier (France) during a conference that gave a state of the art panorama and discussed the perspectives about "Subduction Zone Geodynamics". The papers included in this special volume offer a unique multidisciplinary picture of the recent research on subduction zones geodynamics. They are organized into five main topics: Subduction zone geodynamics, Seismic tomography and anisotropy, Great subduction zone earthquakes, Seismogenic zone characterization, Continental and ridge subduction processes. Each of the 13 papers collected in the present volume is primarily concerned with one of these topics. However, it is important to highlight that papers always treat more than one topic so that all are related lighting on different aspects of the complex and fascinating subduction zones geodynamics.

DOWNLOAD EBOOKThe detachment (break-off or tearing) of portions of subducted tectonic lithosphere has attracted increasing recognition in the past decade as a process that may cause a range of seismic, tectonic, and magmatic observations in a number of locations worldwide (e.g., Baja California, central Mexico, Mediterranean-Carpathian region, India-Asia collision zone, and Tonga-Fiji-New Hebrides-New Zealand region). Slab detachment is a transitory process marking the end of subduction that has major implications for rapid changes in plate motions following loss of the slab pull force driving subduction. Although many studies have focused on the dynamics of subduction initiation and self-sustaining subduction, few have explored the dynamics of the end stage of subduction. I present results of two-dimensional (2-D) and three-dimensional (3-D) numerical models that provide constraints on the rheologic controls on the dynamics of slab detachment, which build upon previous conceptual models, observational studies, and analytic calculations that make up the majority of current slab detachment literature. Results of 2-D models of a stalled subduction scenario demonstrate that (a) the inclusion of a more realistic non-Newtonian upper mantle rheology is necessary for the occurrence of slab detachment, and (b) the timing and depth of detachment depend on slab stiffness (stress supported viscously) as determined by the maximum yield strength and age of the slab. In 2-D models that include a specific possible mechanism for stalled subduction (i.e., ridge-trench collision), slab detachment (a) occurs in all cases before the ridge approaches within ~100 km of the trench due to the increased buoyancy and reduced strength of young lithosphere between ~7-12 My in age, and (b) is first order consistent with observations of offshore ridge abandonment, cessation of subduction, and evidence for slab gap volcanism along Baja California. Three-dimensional model results also demonstrate the same first order rheologic controls on the occurrence of slab detachment as found in the 2-D models and further indicate that (a) 3-D detachment of a finite laterally symmetric slab may occur nearly simultaneously along strike by boudinage-type necking and opening of holes central to the slab, and (b) the approach of offset ridge segments to a trench may lead to vertical slab tearing (along the age-offset and transform-weakened boundary within the subducted slab) and/or horizontal propagation of slab detachment due to lateral transfers in slab pull. In general, the models presented here provide a more quantitative view of slab detachment as a rapid (~1 My) process occurring in the form of shallow (~40-110 km deep) boudinage-type necking of the slab, possibly central to the slab rather than at a slab edge, and with possible lateral tear propagation speeds up to ~100 km/My through young (

DOWNLOAD EBOOKDynamics of Plate Tectonics and Mantle Convection, written by specialists in the field, gathers state-of-the-art perspectives on the dynamics of plate tectonics and mantle convection. Plate tectonics is a unifying theory of solid Earth sciences. In its initial form, it was a kinematic theory that described how the planet’s surface is fragmented into several rigid lithospheric plates that move in relation to each other over the less viscous asthenosphere. Plate tectonics soon evolved to describe the forces that drive and resist plate movements. The Earth sciences community is now developing a new perspective that looks at plate tectonics and mantle convection as part of a single system. Why does our planet have plate tectonics, and how does it work? How does mantle convection drive the supercontinent cycle? How have tectono-convective modes evolved over the Earth’s history? How did they shape the planet and impact life? Do other planets have mantle convection and tectonics? These are some of the fascinating questions explored in this book. This book started with a challenge from the editor to the authors to provide perspectives from their vantage point and open the curtain to the endeavors and stories behind the science. Provides diverse perspectives from different experts around the world in plate tectonics and geodynamics Includes the most up-to-date knowledge on plate tectonics and mantle convection Sets the scene for the developments and challenges likely to be faced by researchers in the future of geodynamics

DOWNLOAD EBOOKThis book is devoted to the quantitative physical modeling of subduction and subduction-related processes. It presents a coherent description of the modeling method (including similarity criteria, and a novel applied experimental technique), results from model experiments, theoretical analysis of results on the basis of continuum mechanics, and their geodynamic interpretation. Subduction is modeled in general as well as applied to particular regions using both 2-D and 3-D approaches, with both slab-push and slab-pull driving forces. The modeling covers all stages from subduction initiation to `death', different regimes of subduction producing back arc extension and compression, blocking of subduction and jumps of subduction zone, arc-continent collision and continental subduction. This work is for geologists and geophysicists interested in geodynamics of the convergent plate boundaries and in mechanics of the lithosphere.
