With the recent catastrophe in Indonesia, the topic of tsunamis could not be more timely. This book, volume fifteen in a distinguished series surveying the frontiers of ocean science and research, looks at every aspect of the current science of tsunamis. The world's foremost experts write about the dynamics of geophysical processes involved in tsunami generation, propagation, and inundation, along with the statistical and geophysical properties of tsunami recurrence, and their application to tsunami forecasts and warnings. Together, their work constitutes the first comprehensive overview of a topic of paramount importance in ocean science today. Coinciding with the recent completion of the United States, enhanced tsunami warning program - which will provide an unprecedented volume of data on tsunamis in the deep ocean - this book will help crystallize a research agenda and foster the study of this critical issue in our understanding of the sea.In the manifold, multidisciplinary efforts of science to understand and manage our planet, contemporary ocean science plays an essential role. This new volume in the series "The Sea" advances these efforts with a clear focus on one of the ocean's more significant deadly phenomena.
