This is the second of two volumes devoted to earthquakes and multi-hazards around the Pacific Rim. The circum-Pacific seismic belt is home to roughly 80% of the world’s largest earthquakes, making it the ideal location for investigating earthquakes and related hazards such as tsunamis and landslides. Following the Introduction, this volume includes 14 papers covering a range of topics related to multi-hazards. The book is divided into five sections: viscoelastic deformation, earthquake source models, earthquake prediction, seismic hazard assessment, and tsunami simulation. Viscoelastic relaxation can play an important role in subduction zone behavior, and this is explored in the first section, with specific examples including the Tohoku-oki earthquake in Eastern Japan. In addition to laboratory rock friction experiments, the second section examines earthquake source models for the 2016 MW 6.6 Aketao earthquake in Eastern Pamir and two earthquakes in Eastern Taiwan, along with strong ground motion studies of the 2008 MW 7.9 Wenchuan, China earthquake. The Load/Unload Response Ratio (LURR), Natural Time (NT), and “nowcasting” are earthquake prediction techniques that are analyzed in the third section, with nowcasting predictions performed for a number of large cities globally. Viscoelastic relaxation can play an important role in subduction zone behavior, assessment are the focus of the fourth section, with specific applications to the Himalayan-Tibetan region and the Xianshuihe Fault Zone in Southwest China. In the last section, a new approach in modeling tsunami height distributions is described. Rapid advances are being made in our understanding of multi-hazards, as well as the range of tools used to investigate them. This volume provides a representative cross-section of how state-of-the-art knowledge and tools are currently being applied to multi-hazards around the Pacific Rim. The material here should be of interest to scientists involved in all areas of multi-hazards, particularly seismic and tsunami hazards. In addition, it offers a valuable resource for students in the geosciences, covering a broad spectrum of topics related to hazard research.

The circum-Pacific seismic belt is home to roughly 80% of the world’s largest earthquakes, making it the ideal location for investigating earthquakes and related hazards such as tsunamis and landslides. Gathering 16 papers that cover a range of topics related to multi-hazards, the book is divided into three sections: earthquake physics, earthquake simulation and data assimilation, and multi-hazard assessment and earthquake forecasting models. The first section includes papers on laboratory-derived rheological parameters as well as seismic studies in the Gulf of California and China. In turn, the second section includes papers on improvements in earthquake simulators as well as the statistical methods used to evaluate their performance, automated methods for determining fault slip using near-field interferometric data, variabilities in earthquake stress drops in California, and the use of social media data to supplement physical sensor data when estimating local earthquake intensity. The final section includes a paper on probabilistic tsunami hazard assessment, several papers on time-dependent seismic hazard analysis around the Pacific Rim, and a paper on induced and triggered seismicity at the Geysers geothermal field in California.

In a world shaped by the forces of nature, humankind has always sought to understand and mitigate the impacts of natural hazards. Natural Hazards - New Insights delves into the intricate realm of floods, earthquakes, tsunamis, meteoritical hazards, mining-related disasters, and other major catastrophes that afflict our planet. This book takes readers on a journey to gain a deeper understanding of these phenomena, unearthing fresh insights into their causes, impacts, and strategies to mitigate their effects. Organized into six comprehensive sections, this book begins with a global perspective on natural hazards, laying the foundation for understanding the diverse range of challenges they pose. It then explores seismic hazards, analyzing earthquake patterns, urban damage assessment, fault reactivation, and more. Shifting the focus to flooding as a natural hazard, the book examines hydrological extremes, flood mapping, and risk reduction strategies. It further explores climatological hazards, including the intricate relationship between climate change and natural disasters, remote sensing technologies, and the impacts of climate change on agriculture. Landslides are also scrutinized as significant natural hazards, with chapters on polarization analysis, landslide assessment, hazard zonation, and the impact of underground coal mining methods on slope stability. Lastly, the book addresses the social challenges that arise when disasters strike, examining psychological reactions, spontaneous volunteers, urban planning responses, and social vulnerability to earthquake hazards. Through peer-reviewed chapters, this book offers valuable insights and expertise from renowned authors in the field. Their contributions have shaped this comprehensive exploration, which aims to navigate the challenges, minimize risks, and build a safer and more sustainable environment for future generations.
This book deals with natural hazards of geophysical, meteorological, hydrological, and biological types that are causing increasing social and economic damage. The development of these hazards and their impact on the living and non-living environment are described in the individual chapters. The compilation synthesises a natural and social geography approach, explores mitigation options and focuses attention on the processes that are most prevalent in Europe and Western Asia, in addition to global phenomena. The author argues that, with the right knowledge and preparedness, the wide-ranging impacts of natural hazards intertwined with climate change can be reduced. This work provides a wealth of digitally accessible professional information to help readers identify and manage natural hazards. The book is useful for students, educators, professionals, practitioners, and those interested in decision making.
Devastating natural disasters have profoundly shaped human history, leaving us with a respect for the mighty power of the earth—and a humbling view of our future. Paleontologist and geologist Donald R. Prothero tells the harrowing human stories behind these catastrophic events. Prothero describes in gripping detail some of the most important natural disasters in history: • the New Madrid, Missouri, earthquakes of 1811–1812 that caused church bells to ring in Boston • the 2004 Indian Ocean tsunami that killed more than 230,000 people • the massive volcanic eruptions of Krakatau, Mount Tambora, Mount Vesuvius, Mount St. Helens, and Nevado del Ruiz His clear and straightforward explanations of the forces that caused these disasters accompany gut-wrenching accounts of terrifying human experiences and a staggering loss of human life. Floods that wash out whole regions, earthquakes that level a single country, hurricanes that destroy everything in their path—all are here to remind us of how little control we have over the natural world. Dramatic photographs and eyewitness accounts recall the devastation wrought by these events, and the people—both heroes and fools—that are caught up in the earth's relentless forces. Eerie, fascinating, and often moving, these tales of geologic history and human fortitude and folly will stay with you long after you put the book down.
Scientific reportage on what we know and don’t know about the mega-earthquake predicted to hit the Pacific Northwest Scientists have identified Seattle, Portland, and Vancouver as the urban centers of what will be the biggest earthquake—the Really Big One—in the continental United States. A quake will happen—in fact, it’s actually overdue. The Cascadia subduction zone is 750 miles long, running along the Pacific coast from Northern California up to southern British Columbia. In this fascinating book, The Seattle Times science reporter Sandi Doughton introduces readers to the scientists who are dedicated to understanding the way the earth moves and describes what patterns can be identified and how prepared (or not) people are. With a 100% chance of a mega-quake hitting the Pacific Northwest, this fascinating book reports on the scientists who are trying to understand when, where, and just how big The Big One will be.
A puzzling tsunami entered Japanese history in January 1700. Samurai, merchants, and villagers wrote of minor flooding and damage. Some noted having felt no earthquake; they wondered what had set off the waves but had no way of knowing that the tsunami was spawned during an earthquake along the coast of northwestern North America. This orphan tsunami would not be linked to its parent earthquake until the mid-twentieth century, through an extraordinary series of discoveries in both North America and Japan. The Orphan Tsunami of 1700, now in its second edition, tells this scientific detective story through its North American and Japanese clues. The story underpins many of today�s precautions against earthquake and tsunami hazards in the Cascadia region of northwestern North America. The Japanese tsunami of March 2011 called attention to these hazards as a mirror image of the transpacific waves of January 1700.
