This volume attempts to present the current state of seismic research by focusing not only on the modeling of earthquakes and earthquake generated tsunamis, but also on practical comparisons of the resulting phenomenology. In the 1990s, major advancements in seismic research greatly added to the understanding of earthquake fault systems as complex dynamical systems. Large quantities of new and extensive remote sensing data sets provided information on the solid earth.

This issue contains 16 papers, presenting work on tsunami hazards, earthquakes, and related computational infrastructure. The integration of multihazard simulations and remotely sensed observations is providing enormous benefits to earthquake and tsunami research. Earthquakes cause damage, but also generate tsunamis, which create additional damage. Remotely sensed observations coupled with geologic field measurements and simulations contribute to our understanding of earthquake processes, which is necessary for mitigating loss of life and property from these damaging events. This book focuses on assimilation of remotely sensed observations to advance multihazards simulation. This capability provides a powerful virtual laboratory to probe earthquake behavior and the earthquake cycle. Hence, it offers a new opportunity to gain understanding of the earthquake nucleation process, precursory phenomena, and space-time seismicity patterns needed for breakthrough advances in earthquake forecasting and hazard quantification.

This book introduces a framework of tsunami modelling from generation to propagation, aimed at application to the new observation started in Japan after the devastating tsunami of the 2011 Tohoku-Oki earthquake. About 150 seismic and tsunami sensors were deployed in a wide region off the Pacific coast of eastern Japan in order to catch tsunami generation inside the focal area, which makes a clear departure from conventional observations that detect tsunamis far from the source region. In order to exploit the full potential of this new observation system, it is not enough to model tsunami generation simply by static sea-bottom deformation caused by an earthquake. This book explains dynamic tsunami generation and sea-bottom deformation by kinematic earthquake faulting, in which seismic and acoustic waves are also included in addition to static sea-bottom deformation. It then systematically derives basic tsunami equations from the fundamental equations of motions. The author also illustrates the details of numerical schemes and their applications to tsunami records, making sound linkages among these topics to naturally understand how a tsunami is physically or mathematically described. This book will be a comprehensive guide for graduate students and young researchers to start their research activities smoothly.

Many coastal areas of the United States are at risk for tsunamis. After the catastrophic 2004 tsunami in the Indian Ocean, legislation was passed to expand U.S. tsunami warning capabilities. Since then, the nation has made progress in several related areas on both the federal and state levels. At the federal level, NOAA has improved the ability to detect and forecast tsunamis by expanding the sensor network. Other federal and state activities to increase tsunami safety include: improvements to tsunami hazard and evacuation maps for many coastal communities; vulnerability assessments of some coastal populations in several states; and new efforts to increase public awareness of the hazard and how to respond. Tsunami Warning and Preparedness explores the advances made in tsunami detection and preparedness, and identifies the challenges that still remain. The book describes areas of research and development that would improve tsunami education, preparation, and detection, especially with tsunamis that arrive less than an hour after the triggering event. It asserts that seamless coordination between the two Tsunami Warning Centers and clear communications to local officials and the public could create a timely and effective response to coastal communities facing a pending tsuanami. According to Tsunami Warning and Preparedness, minimizing future losses to the nation from tsunamis requires persistent progress across the broad spectrum of efforts including: risk assessment, public education, government coordination, detection and forecasting, and warning-center operations. The book also suggests designing effective interagency exercises, using professional emergency-management standards to prepare communities, and prioritizing funding based on tsunami risk.

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.

This book presents a series of numerical simulation studies of the earthquake generation process and the evaluation of the hazards caused by large earthquakes and tsunamis, drawn from three distinct topical areas. First, recent research results on earthquake source physics are introduced, which can be used as input for hazard evaluation studies. Then, propagation of seismic waves and tsunamis is discussed, connecting what happens at the source with the resulting damage. Finally, earthquake statistics for forecasting are discussed, a practical application of our knowledge for the mitigation of earthquake and tsunami disasters. This book is suitable for graduate students who are interested in the earthquake generation process and its application in the future. It also will serve researchers who want or need to know how to evaluate the damage due to earthquakes and tsunamis.
