Abstract

This book is devoted to different aspects of tectonic researches. New results and interpretations are presented here for diverse tectonic settings. Most of the chapters include up-to-date materials of detailed geological investigations, often combined with geophysical data, which can help understand more clearly the essence of mechanisms of different tectonic processes. Some chapters are devoted to the tectonic evolution of regions (East Antarctica, East Kazakhstan, Mongolo-Okhotsk orogenic belt), and others have dealt with the different aspects of tectonic events: influence of detachment structural deformation on pore structure evolution in shales, evolution of drainage in response to brittle-ductile dynamics and surface processes, soft sediment deformation structures triggered by the modern earthquakes, and post-opening deformation history of the Japan Sea back-arc basin.

Abstract

Owing to their unique magnetic, phosphorescent, and catalytic properties, rare earths are the elements that make possible teverything from the miniaturization of electronics, to the enabling of green energy and medical technologies, to supporting essential telecommunications and defense systems. An iPhone uses eight rare earths for everything from its colored screen, to its speakers, to the miniaturization of the phone’s circuitry. On the periodic table rare earth elements comprise a set of seventeen chemical elements (the fifteen lanthanides plus scandium and yttrium). There would be no Pokémon Go without rare earths. Rare Earth Frontiers is a work of human geography. Klinger looks historically and geographically at the ways rare earth elements in three discrete but representative and contested sites are given meaning.

Abstract

This open access book provides a comprehensive overview of volcanic crisis research, the goal being to establish ways of successfully applying volcanology in practice and to identify areas that need to be addressed for future progress. It shows how volcano crises are managed in practice, and helps to establish best practices. Consequently the book brings together authors from all over the globe who work with volcanoes, ranging from observatory volcanologists, disaster practitioners and government officials to NGO-based and government practitioners to address three key aspects of volcanic crises. First, the book explores the unique nature of volcanic hazards, which makes them a particularly challenging threat to forecast and manage, due in part to their varying spatial and temporal characteristics. Second, it presents lessons learned on how to best manage volcanic events based on a number of crises that have shaped our understanding of volcanic hazards and crises management. Third, it discusses the diverse and wide-ranging aspects of communication involved in crises, which merge old practices and new technologies to accommodate an increasingly challenging and globalised world. The information and insights presented here are essential to tapping established knowledge, moving towards more robust volcanic crises management, and understanding how the volcanic world is perceived from a range of standpoints and contexts around the globe. ; A unique collection harnessing international expertise and experience to review volcanic crises around the world Brings together for the first time a wealth of undocumented knowledge to provide a platform for understanding how volcano crises are managed in practice, and to establish effective best practices Includes a glossary, bibliography, and annotated further reading lists, along with a linked author website

Abstract

Rare earth elements (REE) are critical to our modern way of life, although potential primary and secondary sources of these elements and the economics of the REE sector remain somewhat poorly understood. This Special Issue focuses on furthering our understanding of the criticality and potential sources of rare earth elements as well as the economics of the REE sector. The papers in this Special Issue provide further insight into the full life cycle of REE, information that is vital to ensuring the existence of sustainable sources of these critical elements into the future.

Abstract

This thesis aims to contribute to the geomorphological and geo-ecological knowledge of the Schist Mountains in the western sector of the Portuguese Central Range. This second part, the current one, focuses on the role played by man, as the main responsible agent for the evolution of the slopes over the last millennium, in which the construction of agricultural fields is emphasized. The first part of this research deals with the geomorphological analysis and is developed in three chapters: the morpho-structural framework, the landforms and the alluvial deposits, respectively. The second part, centred in the quantification of processes, is more focused on the environment and shows more geo-ecological concerns. It corresponds to chapters fourth and fifth; the former is dedicated to the hydro-climatology, which is the main agent of the morphogenesis and of the recent and current evolution of the slopes , whilst the latter addresses the human intervention and the ecosystems changes.

Abstract

Risk assessment is one of the main parts of complex systematic research of natural and man-made hazards and risks together with the concepts of risk analysis, risk management, acceptable risk, and risk reduction. It is considered as the process of making a recommendation on whether existing risks are acceptable and present risk control measures are adequate, and if they are not, whether alternative risk control measures are justified or will be implemented. Risk assessment incorporates the risk analysis and risk evaluation phases. Risk management is considered as the complete process of risk assessment, risk control, and risk reduction. The book reflects on the state-of-the-art problems and addresses the risk assessment to establish the criteria for ranking risk posed by different types of natural or man-made hazards and disasters, to quantify the impact that hazardous event or process has on population and structures, and to enhance the strategies for risk reduction and avoiding.

Abstract

This book is focused on different aspects of geophysical research, particularly on modern approach in subsurface imaging, tectonics, geohazard, seismicity, and Earth planetary system. Syntheses of results from regional and local studies combined with new techniques of geophysical data acquisition and interpretation from diverse geological provinces are presented. Some of the chapter explained clearly the geophysical technic that can image local sources in urban and rural settings in Israel. An example of studies on basement tectonics and fault reactivation in North America using integrated geophysical methods is also presented. Two modes of seismicity, one involving rotational seismology and another based on seismic response in Mexico using Hilbert-Huang transform (HHT) as an alternative technique for extracting data that will be useful for the assessment of potential earthquake, are discussed in other sets of chapters. The integration of geoelectric methods in another chapter demonstrated delimitation of the resistivity anomalies caused by different types of hydrocarbon contaminants and rocks in rural, industrial, and urban sites. The results of electrical resistivity method to define 1D and 2D electrical models from two datasets acquired in dry and rainy seasons in Panama (Central America) were used to show the relationship between electrical resistivity and volumetric water content. Petrophysical analyses show good fits between resistivity and volumetric water content and known parameters for rocks and soils. The study on Earth planetary system noted that at all stages of the Earth?s formation, convective heat and mass transfer are the most important factors in the dynamics of the planet. The chapter on magnetics shows how remanent magnetization and self-demagnetization complicate the inversion and interpretation of magnetic anomaly with examples from iron deposit in South Australia.
