This is the first 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. 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. 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.

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 author examines natural disasters around the Pacific Rim throughout history together with scientific data context to produce enlightening—and highly readable—entries. On March 11, 2011, a magnitude 9.0 earthquake struck off Japan's coast, triggering a powerful tsunami. The massive destruction that resulted proved that not even sophisticated, industrialized nations are immune from nature's fury. Written to take some of the mystery out of the earth's behavior, this encyclopedia chronicles major natural disasters that have occurred around the Pacific Rim, an area nicknamed the "Ring of Fire" because of the volatile earth that lies above and below. The encyclopedia offers descriptions of deadly earthquakes, volcanic eruptions, and tsunamis through time. The entries provide in-depth information that promotes an understanding of the structure of the earth and earth processes and shares the insights of scientists whose work helps clarify the causes and effects of these cataclysmic events. At the same time, the work examines how the people and cultures of the Pacific Rim view this active part of the earth, how they live with the threat of disaster, and how they have been affected by major events that have occurred. Readers will come away with a holistic view of what is known, how this knowledge was gained, and what its implications may be.

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.

The mega-earthquake occurred on February 27 of March 2010, along the coast of the central Chile in South America, produced an early and shacked weak up to millions of people. The 8.8 Richter scale event hit the central zone at 03:34 A.M. while people were sleeping. Then, as if the damage weren't enough and still at dark, it was followed by a not only devastating but also lethal tsunami that was strong enough to travel across the Pacific Ocean, hitting Asia only fourteen hours after. This earthquake is the fifth more intense ever measured and it was so strong that Scientific American published in the March 4th newsletter the following article: "The magnitude 8.8 earthquake that jolted Chile on Saturday was felt as far away as São Paulo. But NASA scientists are proposing that its repercussions are truly global in a geophysical sense: it likely shifted Earth's axis by about eight centimeters." But unfortunately the tragedy didn't stop with the earthquake. It also originated a tsunami that hit the coast with 4 waves, the first arriving just a few minutes after the earthquake and the last, several hours after. This tsunami was so strong that it has been detected that at least one wave was 30 meters or 98 feet high. Before continuing I would like to prevent lecturers from falling into the temptation of thinking that this mega-nature-events, only happen in faraway lands affecting people quite different from us. The Indonesian Tsunami of December 2004 was very distant from Chile not only in miles but also in cultural terms. And now, it's clear that Indonesian experience helped to prevent more fatalities. That's why this book has been written to urge people living in the Pacific Rim, to take some time to analyze their situation, the one of each community and act in order to prevent or reduce potential damages and casualties.

Large-scale earthquake hazards pose major threats to modern society, generating casualties, disrupting socioeconomic activities, and causing enormous economic loss across the world. Events, such as the 2004 Indian Ocean tsunami and the 2011 Tohoku earthquake, highlighted the vulnerability of urban cities to catastrophic earthquakes. Accurate assessment of earthquake-related hazards (both primary and secondary) is essential to mitigate and control disaster risk exposure effectively. To date, various approaches and tools have been developed in different disciplines. However, they are fragmented over a number of research disciplines and underlying assumptions are often inconsistent. Our society and infrastructure are subjected to multiple types of cascading earthquake hazards; therefore, integrated hazard assessment and risk management strategy is needed for mitigating potential consequences due to multi-hazards. Moreover, uncertainty modeling and its impact on hazard prediction and anticipated consequences are essential parts of probabilistic earthquake hazard and risk assessment. The Research Topic is focused upon modeling and impact assessment of cascading earthquake hazards, including mainshock ground shaking, aftershock, tsunami, liquefaction, and landslide.
