Landslides

Do you know what a landslide is? Where landslides happen? How to stay safe if a landslide is coming? Read this book and discover the answers!

Around the world, geological phenomena shape landscapes and create breathtaking scenery. In language fit for the youngest geologists, Earth Rocks! explores six geological formations and phenomena, explaining how they form or occur as well as any damages they may cause. Photographs of famous locations and events complement the text, while a closing activity encourages applied understanding of important scientific concepts. An elementary exploration of landslides, focusing on the geological evidence that helps explain how and where they form and spotlighting famous examples, such as the 2013 Indian landslides.

A comprehensive, one-stop synthesis of landslide science, for researchers and graduate students in geomorphology, engineering geology and geophysics.

This volume is the second in the new Safety and Security Engineering series that is designed to provide a comprehensive view on risk mitigation. This volume is devoted to landslides and debris flow, addressing the need for a better understanding of these increasingly frequent phenomena. With better understanding comes a greater ability to manage the attendant risk.The present volume contains selected research papers presented at Wessex Institute of Technology Conferences. The book will be a valuable reference for professionals, scientists, and managers concerned with prediction and management of the risk of landslides and debris flows.

Landslides and Engineered Slopes. Experience, Theory and Practice contains the invited lectures and all papers presented at the 12th International Symposium on Landslides, (Naples, Italy, 12-19 June 2016). The book aims to emphasize the relationship between landslides and other natural hazards. Hence, three of the main sessions focus on Volcanic-induced landslides, Earthquake-induced landslides and Weather-induced landslides respectively, while the fourth main session deals with Human-induced landslides. Some papers presented in a special session devoted to "Subareal and submarine landslide processes and hazard” and in a “Young Session” complete the books. Landslides and Engineered Slopes. Experience, Theory and Practice underlines the importance of the classic approach of modern science, which moves from experience to theory, as the basic instrument to study landslides. Experience is the key to understand the natural phenomena focusing on all the factors that play a major role. Theory is the instrument to manage the data provided by experience following a mathematical approach; this allows not only to clarify the nature and the deep causes of phenomena but mostly, to predict future and, if required, manage similar events. Practical benefits from the results of theory to protect people and man-made works. Landslides and Engineered Slopes. Experience, Theory and Practice is useful to scientists and practitioners working in the areas of rock and soil mechanics, geotechnical engineering, engineering geology and geology.

Landslides represent one of the most destructive natural catastrophes. They can reach extremely long distances and velocities, and are capable of wiping out human communities and settlements. Yet landslides have a creative facet as they contribute to the modification of the landscape. They are the consequence of the gravity pull jointly with the tectonic disturbance of our living planet. Landslides are most often studied within a geotechnical and geomorphological perspective. Engineering calculations are traditionally applied to the stability of terrains. In this book, landslides are viewed as a physical phenomenon. A physical understanding of landslides is a basis for modeling and mitigation and for understanding their flow behavior and dynamics. We still know relatively little about many aspects of landslide physics. It is only recently that the field of landslide dynamics is approaching a more mature stage. This is testified by the release of modelling tools for the simulation of landslides and debris flows. In this book the emphasis is placed on the problems at the frontier of landslide research. Each chapter is self-consistent, with questions and arguments introduced from the beginning.

This book presents current progress in landslide science and consists of four parts: progress in landslide science, landslide dynamics, landslide monitoring, and landslide risk assessment. It provides useful information to those working on landslide risk-mitigation planning. It can be also used as an introductory textbook for college students who wish to learn fundamental scientific achievements in the field of landslide disaster reduction.

The majority of the 1998 Wasatch Front landslides were likely triggered following a cumulative rise in ground-water levels resulting from four or more successive years of above-normal precipitation. Triggering of landslide movement likely coincided with a transient ground-water-level rise associated with the spring snowmelt and contemporaneous above-normal precipitation. In most Wasatch Front areas, 1998 was the wettest as well as the last year of the precipitation period. An increase in landslide activity began in 1997, following two to four successive years of above-normal precipitation. This study examines the relation between the 1998 landslides and the 1995-98 precipitation period (1993-98 in Spanish Fork Canyon). Accordingly, this study investigates the significance of the most recent precipitation period in relation to the historical precipitation record, and compares it with the 1980-86 period. In addition, other causes of the 1998 landsliding are explored, most importantly hillside modification related to residential development. This study also examines several issues, and their implications, related to the 1998 Wasatch Front landslides including the susceptibility to reactivation of pre-existing landslides, consideration of the state of landslide activity, and the possibility of developing landslide-movement prediction tools based on an instability threshold concept. The majority of the landslides discussed occurred near urbanized areas of the Wasatch Front and consisted of either translational or rotational earth slides in pre-existing landslide areas. The discussion and conclusions are limited to these landslides and locations. The case histories presented provide new data intended to further the understanding of landslide hazards in the Wasatch Front.
