This volume contains papers of the 9th European Workshop on the Seismic Behaviour of Irregular and Complex Structures (9EWICS) held in Lisbon, Portugal, in 2020. This workshop, organized at Instituto Superior Tecnico, University of Lisbon, continued the successful three-annual series of workshops started back in 1996. Its organization had the sponsorship of Working Group 8 (Seismic Behaviour of Irregular and Complex Structures) of the European Association of Earthquake Engineering.This international event provided a platform for discussion and exchange of ideas and unveiled new insights on the possibilities and challenges of irregular and complex structures under seismic actions. The topics addressed include criteria for regularity, seismic design of irregular structures, seismic assessment of irregular and complex structures, retrofit of irregular and complex structures, and soil-structure interaction for irregular and complex structures. Beyond an excellent number of interesting papers on these topics, this volume includes the papers of the two invited lectures - one devoted to irregularities in RC buildings, including perspectives in current seismic design codes, difficulties in their application and further research needs, and another one dedicated to the challenging and very up to date topic in the area of seismic response of masonry building aggregates in historical centers. This volume includes 26 contributions from authors of 11 countries, giving a complete and international view of the problem.The holds particular interest for all the community involved in the challenging task of seismic design, assessment and/or retrofit of irregular and complex structures.

Science Is Never "Settled" Thousands of scientists are convinced beyond any reasonable doubt that recent global warming is being caused by emissions of greenhouse gases and that we must act immediately to reduce these emissions or else we may render Earth unlivable for our children and our grandchildren. Some even say "the science is settled." What Really Causes Global Warming examines a broad range of observations that show that greenhouse warming theory is not only misguided, but not physically possible. Recent warming was caused by ozone depletion due to emissions of human-manufactured gases. We solved that problem with the Montreal Protocol on Substances that Deplete the Ozone Layer stopping the increase in global temperatures by 1998. Volcanoes also deplete ozone. The eruption of Bardarbunga volcano in central Iceland from August 2014 to February 2015-the largest effusive, basaltic, volcanic eruption since 1783-caused 2015 to be the hottest year on record. How can we adapt? "The work of science has nothing whatever to do with consensus. Consensus is the business of politics. Science, on the contrary, requires only one investigator who happens to be right, which means that he or she has results that are verifiable by reference to the real world."- Michael Crichton, 2003

Ground motion due to earthquake excitation often induces disastrous disturbances that severely damage structures and their contents. Conventional earthquake-resistant design focuses on the strengthening of structures to avoid collapse, while little attention is paid to the prevention of damage as it is almost impossible to construct completely "earthquake proof" structures at reasonable cost. This state-of-the-art volume explores seismic isolation as an alternative and performance-based design approach to minimise earthquake induced loads and resulting damage in low to medium-rise buildings. A discussion of the characteristics, advantages and limitations of seismic isolation is followed by a demonstration of its capability to decouple a structure from the damaging effects of ground acceleration. Describes currently used seismic isolation systems in detail. Evaluates the performance of seismically isolated structures and provides examples of their response under earthquake action. Proposes a preliminary design methodology for seismically isolated structures. Accessible to both students and practising structural engineers who need to familiarise themselves with this approach.

An unexpected brittle failure of connections and of members occurred during the last earthquakes of Northridge and Kobe. For this reason a heightened awareness developed in the international scientific community, particularly in the earthquake prone countries of the Mediterranean and Eastern Europe, of the urgent need to investigate this topic. The contents of this volume result from a European project dealing with the 'Reliability of moment resistant connections of steel frames in seismic areas' (RECOS), developed between 1997 and 1999 within the INCO-Copernicus joint research projects of the 4th Framework Program. The 30 month project focused on five key areas: *Analysis and syntheses of research results, including code provisos, in relation with the evidence of the Northridge and Kobe earthquakes; *Identification and evaluation through experimental means of the structural performance of beam-to-column connections under cyclic loading; *Setting up of sophisticated models for interpreting the connection response; *Numerical study on the connection influence on the seismic response of steel buildings; *Assessment of new criteria for selecting the behaviour factor for different structural schemes and definition of the corresponding range of validity in relation of the connection typologies.

Volcanoes & Earthquakes features the earth sciences at their most spectacular. It reveals the massive internal forces that create and change the Earth's surface, with dramatic and sometimes beautiful consequences. The authors explain what fuels the power of volcanoes and earthquakes and explore how the gradual shifting of tectonic plates has transformed the Earth over its four and a half thousand million year existence. Written in a jargon-free style and fully illustrated with photographs, diagrams and maps, this is a cutting-edge introduction to earthquakes, volcanoes and plate tectonics, incorporating all the latest research developments.Chiara Maria Petrone is a Research Leader in Petrology and Volcanology in the Earth Sciences Department of the Natural History Museum, London. Roberto Scandone is a Research Associate at the Vesuvius Observatory, National Institute of Geophysics and Volcanology, Naples. Alex Whittaker is a Senior Lecturer in Tectonics in the Department of Earth Science and Engineering at Imperial College, London.

Our consumption of raw materials and energy has reached unprecedented levels which are continuing to increase at a steady rate due to the economic emergence of many countries and the development of new technologies. Metal and cement usage has doubled since the beginning of the 21st Century and this production, between now and 2050, will be equivalent to that produced since the beginning of humanity. It is in this context that the transition to low-carbon and renewable energies is taking place, which involves profound changes to the existing global energy system. This book addresses these different aspects and attempts to estimate first-order requirements for cement, steel, copper, aluminum and energy for different power generation technologies, and for three types of energy scenarios. Some dynamic modeling approaches are proposed to assess the needs and likely evolution of primary production and recycling. The link between production and primary reserves, recycling and stocks of end-of-life products, production costs, incomes and prices using a prey-predator dynamic is discussed.

The Indian Ocean tsunami of December 2004 is considered to have been one of the worst natural disasters in history, affecting twelve countries, from Indonesia to Somalia. 175,000 people are believed to have lost their lives, almost 50,000 were registered as missing and 1.7 million people were displaced. As well as this horrendous toll on human life, the tsunami destroyed property worth billions of dollars and ruined many local economies. Based on their experience and analysis of this tsunami, the authors have developed methodologies for predicting and preparing for tsunamis. A basis is provided for a cost-effective warning and preparedness strategy, drawing on the example of existing systems used in earthquake disaster management and tidal wave warning, from genesis to impact. The book comprehensively addresses the fundamentals of tsunami science, identifying potential areas where tsunamis might be generated, predicting the anticipated course of tsunamis and considering how the geophysical, ecological and socioeconomic location of a community may determine the severity of tsunami damage. The authors suggest how precursors can be used to enhance the advance warning time, how tsunamis can be detected at the time of their occurrence, and the manner in which warnings should be communicated to the populations likely to be affected. Finally, improvement in eco-sociological resilience through the application of dual-use technologies is identified as a pivotal aid in allowing coastal communities to be better prepared. The book will be of interest to a global audience of professionals and academics active in seismology, ocean science, meteorology, coastal management, earthquake engineering and disaster management.

'In summary, Professor Slawinski has written an engaging volume covering an unfamiliar topic in a highly accessible fashion. Non-specialists will gain a significant appreciation of the unique complexities associated with seismology.'Contemporary PhysicsThe author dedicates this book to readers who are concerned with finding out the status of concepts, statements and hypotheses, and with clarifying and rearranging them in a logical order. It is thus not intended to teach tools and techniques of the trade, but to discuss the foundations on which seismology - and in a larger sense, the theory of wave propagation in solids - is built. A key question is: why and to what degree can a theory developed for an elastic continuum be used to investigate the propagation of waves in the Earth, which is neither a continuum nor fully elastic. But the scrutiny of the foundations goes much deeper: material symmetry, effective tensors, equivalent media; the influence (or, rather, the lack thereof) of gravitational and thermal effects and the rotation of the Earth, are discussed ab initio. The variational principles of Fermat and Hamilton and their consequences for the propagation of elastic waves, causality, Noether's theorem and its consequences on conservation of energy and conservation of linear momentum are but a few topics that are investigated in the process to establish seismology as a science and to investigate its relation to subjects like realism and empiricism in natural sciences, to the nature of explanations and predictions, and to experimental verification and refutation.In the second edition, new sections, figures, examples, exercises and remarks are added. Most importantly, however, four new appendices of about one-hundred pages are included, which can serve as a self-contained continuum-mechanics course on finite elasticity. Also, they broaden the scope of elasticity theory commonly considered in seismology.

Coding and Decoding Seismic Data: The Concept of Multishooting, Volume One, Second Edition, offers a thorough investigation of modern techniques for collecting, simulating, and processing multishooting data. Currently, the acquisition of seismic surveys is performed as a sequential operation in which shots are computed separately, one after the other. The cost of performing various shots simultaneously is almost identical to that of one shot; thus, the benefits of using the multishooting approach for computing seismic surveys are enormous. By using this approach, the longstanding problem of simulating a three-dimensional seismic survey can be reduced to a matter of weeks. Providing both theoretical and practical explanations of the multishooting approach, including case histories, this book is an essential resource for exploration geophysicists and practicing seismologists.

Routine seismic monitoring in mines was introduced over 30 years ago with two main objectives in mind: * immediate location of larger seIsmIC events to guide rescue operations; * prediction of large rockmass instabilities. The first objective was achieved fairly quickly, but with the subsequent development of mine communication systems, its strategic importance has diminished. The very limited success with prediction can, at least partially, be attributed to three factors: * seismic monitoring systems based on analogue technology that provided noisy and, frequently, poorly calibrated data of limited dynamic range; * the non-quantitative description of a seismic event by at best its local magnitude; and * the resultant non-quantitative analysis of seismicity, frequently through parameters of some statistical distributions, with a somewhat loose but imaginative physical interpretation. The introduction of modern digital seismic systems to mines and progress in the theory and methods of quantitative seismology have enabled the implementation of realtime seismic monitoring as a management tool, quantifying rockmass response to mining and achieving the first tangible results with prediction. A seismic event, being a sudden inelastic deformation within the rockmass, can now routinely be quantified in terms of seismic moment, its tensor, and radiated seismic energy, so that the overall size of, and stress released at, the seismic source can be estimated.

Impacts and Insights of Gorkha Earthquake in Nepal offers a practical perspective on disaster risk management using lessons learned and considerations from the 2015 Gorkha earthquake in Nepal, which was the worst disaster to hit Nepal since the 1934 Nepal-Bihar earthquake. Using a holistic approach to examine seismicity, risk perception and intervention, the book serves as a detailed case study to improve disaster resilience globally, including social, technical, governmental and institutional risk perception, as well as scientific understanding of earthquake disasters. Covering the details of the Gorkha earthquake, including damage mapping and recovery tactics, the book offers valuable insights into ways forward for seismologists, earthquake researchers and engineers and policy-makers.

'I can wholeheartedly recommend this book students, researchers, college and university science professors, and readers of The Leading Edge.

This book places Oakland's public policy response (nine major ordinances) to building damage suffered in the 1989 Loma Prieta earthquake in a full historical and intergovernmental context. Using a combined non-decision making and advocacy coalition approach, the book demonstrates how and why hazardous-structure abatement was kept off the local political agenda prior to the Loma Prieta disaster. The book then demonstrates how and why city government in Oakland became proactive on the problem of earthquake-damaged and, more importantly, earthquake-vulnerable buildings in general after the disaster.

As one of the most fascinating and volatile forces on earth, volcanoes have long been the subject of worship, fear, and study. With the aid of famous 'case histories' Lopes provides a unique background to volcanoes, what they are, why they form, and how they erupt. From the Sunset Crater in Arizona and Krakatau in Indonesia to the exotic volcanoes of the outer solar system this guide illustrates the dangers of volcanoes and their importance in shaping the world around us.

Originally published in 1993, Active Lavas looks at the practical aspects of monitoring uncontrolled streams of molten rock and how field data can be applied for theoretical modelling and forecasting the growth of lava flows. It describes the basic features of common subaerial lava flows and domes - both on Earth and on other bodies in the Solar System - before discussing the logistics of measuring lava properties during eruption and how these measurements are used to develop simple theoretical models for forecasting flow behaviour.

Originally published in 1995, Monitoring Active Volcanoes is a comprehensive text which addresses the importance of volcano surveillance in the context of forecasting eruptive activity and mitigating its effects. The traditional core of seismic and ground deformation monitoring is discussed, along with more innovative techniques involving the recording of microgravity and micromagnetic variations, and the changing compositions of volcanic gases and liquids. The role of satellites is stressed, particularly with regard to the capabilities for measuring surface deformation, recognizing thermal anomalies and monitoring gas and ash plumes from space platforms. This book provides an invaluable insight into how and why volcanoes are monitored. It will be of interest to volcanologists, geophysicists and earth scientists.
