From Preparation to Faulting: Multidisciplinary Investigations on Earthquake Processes, volume II


Book Description

This Research Topic is Volume II of a series. The previous volume can be found here: From Preparation to Faulting: Multidisciplinary Investigations on Earthquake Processes What happens before an earthquake occurs? What are the physical processes that take place in the Earth’s crust before the earthquake nucleates? How can we observe, describe, and model them statistically, numerically, and physically in multiscales from samples in laboratory to tectonic plate of earth? During the last few decades many efforts have been devoted to multidisciplinary studies in an attempt to answer these fundamental questions. Previously, the Institute of Physics of the Earth (IPE) model (dry) and Dilatancy Diffusion (DD) model (wet) were proposed for earthquake processes. Like Schrödinger's cat, earthquakes are unpredictable—according to the IPE model, yet they can be predictable—according to DD model. Recently, with advanced techniques, some scientists have declaimed that there are precursors to be used for earthquake forecasting, which offers new opportunities to study earthquake precursors.

The book will be useful to individual researchers as well as graduate students for a reference in the field of data assimilation.




Arctic Studies


Book Description

The Arctic region is the keystone to understanding the present status ofcurrently ongoing Earth systems and to predicting future imagesof our planet as viewed from northern high latitudes. The Arctic region,composed of ice-covered Arctic ocean in its center and surroundingfragmentation of the major continents, has been investigatedduring the last half century through all kinds of scientific studies:bioscience, physical sciences, geoscience, oceanography, and environmental studies, together with the technological domain. This book covers topics on the recent developments of all kinds of scientific research in and around the Arctic region, with a view to monitoring the current variations in the extreme environment, affected by remarkable changes in temperature and sea-ice extent, mass loss of ice-sheet and glaciers, and variations in marine and terrestrial ecosystems, including human activities.




The Ocean in Motion


Book Description

This book commemorates the 70th birthday of Eugene Morozov, the noted Russian observational oceanographer. It contains many contributions reflecting his fields of interest, including but not limited to tidal internal waves, ocean circulation, deep ocean currents, and Arctic oceanography. Special attention is paid to studies on internal waves and especially those on tidal internal waves in the Global Ocean. These papers describe the most important open problems concerning experimental studies of internal waves and their theoretical, numerical, and laboratory modeling. Further contributions investigate the physics of surface waves and their interaction with internal waves. Here, the focus is on describing interaction processes between internal waves and deep currents in the ocean, especially currents of Antarctic Bottom Water in abyssal fractures. They also touch on the problem of oceanic circulation and related processes in fjords, including those occurring under sea ice. Given its breadth of coverage, the book will appeal to anyone interested in a survey of ocean dynamics, ranging from historic perspectives to modern research topics.




Crustal Evolution of India and Antarctica


Book Description

The Proterozoic aeon involved at least three major continental readjustments. India and Antarctica appear in most models of supercontinent reconstructions, but their relative position has been the subject of debate. High-resolution petrological and geochronological data, especially from the Proterozoic mobile belts, provide the principal means of resolving this issue. The ice-covered nature of Antarctica allows only limited access to the rocks, and then only in coastal tracts, so detailed studies in more accessible Proterozoic terrains in India assume added significance. This volume, a follow-up to the XII International Symposium on Antarctic Earth Science, Goa (a SCAR symposium), provides new data from selected locations in east Antarctica (Enderby Land and Dronning Maud Land) and from India, including the Eastern Ghats Mobile Belt (EGMB), Chota Nagpur Gneissic Complex, the Khasi Hills and the Aravalli–Delhi Mobile Belt. The presented geochronological data, constrained by petrological studies, are expected to provide new insights, especially into the EGMB–east Antarctica connection and the rate of continental readjustments in the post-Rodinia break-up.




Climate-Resilient Infrastructure


Book Description

Abstract: Prepared by the Committee on Adaptation to a Changing Climate of ASCE Civil infrastructure systems traditionally have been designed for appropriate functionality, durability, and safety for climate and weather extremes during their full-service lives; however, climate scientists inform us that the extremes of climate and weather have altered from historical values in ways difficult to predict or project. Climate-Resilient Infrastructure: Adaptive Design and Risk Management, MOP 140, provides guidance for and contributes to the developing or enhancing of methods for infrastructure analysis and design in a world in which risk profiles are changing and can be projected with varying degrees of uncertainty requiring a new design philosophy to meet this challenge. The underlying approaches in this manual of practice (MOP) are based on probabilistic methods for quantitative risk analysis, and the design framework provided focuses on identifying and analyzing low-regret, adaptive strategies to make a project more resilient. Beginning with an overview of the driving forces and hazards associated with a changing climate, subsequent chapters in MOP 140 provide observational methods, illustrative examples, and case studies; estimation of extreme events particularly related to precipitation with guidance on monitoring and measuring methods; flood design criteria and the development of project design flood elevations; computational methods of determining flood loads; adaptive design and adaptive risk management in the context of life-cycle engineering and economics; and climate resilience technologies. MOP 140 will be of interest to engineers, researchers, planners, and other stakeholders charged with adaptive design decisions to achieve infrastructure resilience targets while minimizing life-cycle costs in a changing climate




Climate Adaptation Futures


Book Description

Adaptation is the poor cousin of the climate change challenge - the glamour of international debate is around global mitigation agreements, while the bottom-up activities of adaptation, carried out in community halls and local government offices, are often overlooked. Yet, as international forums fail to deliver reductions in greenhouse gas emissions, the world is realising that effective adaptation will be essential across all sectors to deal with the unavoidable impacts of climate change. The need to understand how to adapt effectively, and to develop appropriate adaptation options and actions, is becoming increasingly urgent. This book reports the current state of knowledge on climate change adaptation, and seeks to expose and debate key issues in adaptation research and practice. It is framed around a number of critical areas of adaptation theory and practice, including: Advances in adaptation thinking, Enabling frameworks and policy for adaptation, Engaging and communicating with practitioners, Key challenges in adaptation and development, Management of natural systems and agriculture under climate change, Ensuring water security under a changing climate, Urban infrastructure and livelihoods, and The nexus between extremes, disaster management and adaptation. It includes contributions from many of the leading thinkers and practitioners in adaptation today. The book is based on key contributions from the First International Conference on Climate Change Adaptation ‘Climate Adaptation Futures’, held on the Gold Coast, Australia, in June 2010. That three-day meeting of over 1000 researchers and practitioners in adaptation from 50 countries was the first of its kind. Readership: The book is essential reading for a wide range of individuals involved in climate change adaptation, including: Researchers, Communication specialists, Decision-makers and policy makers (e.g. government staff, local council staff), On-ground adaptation practitioners (e.g. aid agencies, government workers, NGOs), Postgraduate and graduate students, and Consultants.
