Submarine slope stability has become an important concern and a subject of research with increasing demand for offshore developments and technological advancement for harsh and challenging environments. The consequences of submarine slope failure adjacent to oil and gas facilities would have a large financial, safety and regulatory impact. This current research work investigates potential failure of submarine gassy slopes triggered by tidal variations. Due to tidal variations, failure of an unsaturated slope may occur under specific combinations of increasing degree of saturation and soil permeability, and decreasing tidal period. Novel physical model tests in a geotechnical centrifuge were undertaken to examine submarine slope failure mechanisms containing gassy sediments. The model preparation techniques, measurement systems and results are presented. The response observed in the model test is discussed and further developments proposed. The buried PPT's response of the submarine slope are comparable in terms of attenuation and phase lag with Nagaswaran (1983) and with field measurements of Atigh and Byrne (2004) in terms of phase lag.

Recent global events such as the devastating 1998 Papua New Guinea tsunami, the 2004 Sumatran tsunami and the 2006 SE Asia undersea network cable failure underscore the societal and economic effects of submarine mass movements. These events call upon the scientific community to understand submarine mass movement processes and consequences to assist in hazard assessment, mitigation and planning. Additionally, submarine mass movements are beginning to be recognized as prevalent in continental margin geologic sections. As such, they represent a significant if not dominant role in margin sedimentary processes. They also represent a potential hazard to hydrocarbon exploration and development, but also represent exploration indicators and targets. This volume consists of a collection of the latest scientific research by international experts in geological, geophysical, engineering and environment aspects of submarine mass failures, focussed on understanding the full spectrum of challenges presented by submarine mass movements and their consequences.

Did you know that the Grand Bank earthquake of 1929 triggered a huge submarine mass movement which broke submarine cables over a distance of up to 1000 km from its source and generated a tsunami which devastated a small village in Newfoundland killing 27 people? The same happened in Papua New Guinea in 1998 with more than 2000 casualties. Submarine mass movements of various sizes and styles are shaping the sea floor and are of concern for many facets of human activities both onshore and offshore. These include the development of natural resources, energy and communication transport, coastal infrastructures and communities. This book provides a world-wide perspective of submarine mass movements and their consequences. This has been made possible by assembling excellent contributions from active researchers, groups, or institutions, thus providing full coverage of the many scientific and engineering aspects of this type of marine and coastal geo-hazard. It covers fundamental as well as site specific studies from many areas including the Atlantic and Pacific oceans, inner seas like the Mediterranean Sea, and fjords using the most recent technologies from multibeam sonar imaging techniques, 3D seismic analysis, slope stability analysis, to debris flow and tsunami modeling. Audience: This book is of interest to any researcher in the field of marine and coastal geo-hazards. It will be useful for planners, scientists and engineers involved in the development of offshore and near-shore resources and also to those in charge of the management and mitigation of coastal hazards. For graduate students, this book provides an up-to-date vision of the process of submarine mass movements and their consequences from both a scientific and an engineering standpoint, and it includes a unique collection of the existing literature on marine geo-hazards. CD-Rom included This volume contains a CD-Rom which in addition to an electronically searchable version of the contributions, has full colour versions of figures which are printed in black and white in the book.

This book is a comprehensive collection of state-of-the-art studies of seafloor slope instability and their societal implications. The volume captures the most recent and exciting scientific progress made in this research field. As the world’s climate and energy needs change, the conditions under which slope instability occurs and needs to be considered, are also changing. The science and engineering of submarine – or more widely subaqueous – mass movements is greatly benefiting from advances in seafloor and sub-seafloor surveying technologies. Ultra-high-resolution seafloor mapping and 3D seismic reflection cubes are becoming commonly available datasets that are dramatically increasing our knowledge of the mechanisms and controls of subaqueous slope failure. Monitoring of slope deformation, repeat surveying and deep drilling, on the other hand, are emerging as important new techniques for understanding the temporal scales of slope instability. In essence, rapid advances in technology are being readily incorporated into scientific research and as a result, our understanding of submarine mass movements is increasing at a very fast rate. The volume also marks the beginning of the third IGCP project for the submarine mass movement research community, IGCP-640 S4SLIDE (Significance of Modern and Ancient Submarine Slope LandSLIDEs). The Submarine Mass Movements and Their Consequences symposium is the biannual meeting under the IGCP umbrella.

Submarine mass movements are widespread at submarine slopes and play an important role in transporting sediments across the continental slope to the deep basin, as well as potential danger to both offshore infrastructures (e.g., pipeline, cables and platforms) and coastal areas (e.g., slope failure-induced tsunamis). This thesis investigates preconditioning factors and triggering mechanisms governing slope instabilities of three distinct submarine landslides areas in passive and active continental margin settings. Geotechnical properties of sediments are used for infinite slope stability of undeformed sediments under various conditions (undrained and drained, each static and earthquake conditions) to identify the preconditioning factors and quantify the influence of earthquakes as a key factor in slope failing mechanisms. The three distinct case studies are located at: (1) the passive continental slope of Uruguay and north of Argentina, (2) the low seismic and tectonically active Gela foreland basin, central Mediterranean continental margin, and (3) the moderate seismic and tectonically active back-arc basin, deeper slope of the Ligurian margin, Southern France.

Physical Modelling in Geotechnics collects more than 1500 pages of peer-reviewed papers written by researchers from over 30 countries, and presented at the 9th International Conference on Physical Modelling in Geotechnics 2018 (City, University of London, UK 17-20 July 2018). The ICPMG series has grown such that two volumes of proceedings were required to publish all contributions. The books represent a substantial body of work in four years. Physical Modelling in Geotechnics contains 230 papers, including eight keynote and themed lectures representing the state-of-the-art in physical modelling research in aspects as diverse as fundamental modelling including sensors, imaging, modelling techniques and scaling, onshore and offshore foundations, dams and embankments, retaining walls and deep excavations, ground improvement and environmental engineering, tunnels and geohazards including significant contributions in the area of seismic engineering. ISSMGE TC104 have identified areas for special attention including education in physical modelling and the promotion of physical modelling to industry. With this in mind there is a special themed paper on education, focusing on both undergraduate and postgraduate teaching as well as practicing geotechnical engineers. Physical modelling has entered a new era with the advent of exciting work on real time interfaces between physical and numerical modelling and the growth of facilities and expertise that enable development of so called ‘megafuges’ of 1000gtonne capacity or more; capable of modelling the largest and most complex of geotechnical challenges. Physical Modelling in Geotechnics will be of interest to professionals, engineers and academics interested or involved in geotechnics, geotechnical engineering and related areas. The 9th International Conference on Physical Modelling in Geotechnics was organised by the Multi Scale Geotechnical Engineering Research Centre at City, University of London under the auspices of Technical Committee 104 of the International Society for Soil Mechanics and Geotechnical Engineering (ISSMGE). City, University of London, are pleased to host the prestigious international conference for the first time having initiated and hosted the first regional conference, Eurofuge, ten years ago in 2008. Quadrennial regional conferences in both Europe and Asia are now well established events giving doctoral researchers, in particular, the opportunity to attend an international conference in this rapidly evolving specialist area. This is volume 2 of a 2-volume set.

Neste trabalho são avaliadas as condições de estabilidade do subsolo marinho ao longo da rota de um duto rígido de aço revestido com concreto, de 10 de diâmetro, localizado na Bacia de Campos, RJ. Os dados geológicos e geotécnicos foram adquiridos a partir de um amplo levantamento geofísico e geotécnico realizado na diretriz do duto. Devido as adversidades à estabilidade do fundo marinho, várias análises vêm sendo realizadas de forma qualitativa e quantitativa. Atualmente, por questões ambientais e de segurança de obras de engenharia, busca-se uma avaliação mais quantitativa dos riscos geológicos associados à condição de estabilidade do fundo marinho, pois os escorregamentos de taludes representam o principal risco para estas estruturas. As análises de estabilidade foram feitas a partir da teoria do talude infinito, em metodologia aplicada por Nowacki et al. (2003) nos campos profundos de Mad Dog e Atlantis, no Golfo do México, e comparadas com os resultados encontrados a partir da formulação clássica do talude infinito. Uma integração de dados geotécnicos e geofísicos foi necessária, para que todos os parâmetros utilizados na metodologia pudessem ser obtidos. Os resultados indicaram dois pontos críticos ao longo da rota, ambos associados aos flancos do cânion Itapemirim, que apresentam gradientes altos. Foram realizados breves estudos com o objetivo de se avaliar a possibilidade de ocorrência de mecanismos disparadores (terremotos e ondas de tempestade) nesses pontos críticos mas os resultados descartaram esta possibilidade. Concluiu-se ainda que os dados geotécnicos utilizados neste trabalho não foram suficientes e de certo modo não apropriados para a análise de estabilidade de taludes. Uma nova campanha de ensaios geotécnicos de laboratório foi proposta para futuros estudos.
