The hazards associated with tsunamis are well known and have been studied for decades. The majority of research is, however, focused on open coastlines which bear the brunt of a tsunamis force. Other regions that can be strongly impacted by a tsunami are large estuaries. Here, the tsunami encounters a long shallow body of water and is able to propagate much further than it would on land. Understanding the extent of tsunami propagation in rivers and the speed at which they propagate is important for the creation of timely and effective warning systems for communities along large estuaries. The present study investigates tsunami inundation and propagation up estuaries as a function of geometric shape, river discharge, and tidal state. This is accomplished by modeling tsunami wave-trains in three highly idealized estuaries, modeling a single tsunami wave-form in a local Columbia River Estuary grid, and by modeling an actual Cascadia Subduction Zone earthquake in a regional Eastern North Pacific grid. Comparison of water surface elevations in the three idealized estuaries indicate that faster estuary convergence causes greater energy dissipation but focuses the remaining energy resulting in higher energy density and larger tsunami waves. Changes in river discharge proved to have a minimal impact on tsunami propagation while changes in tidal state had large impacts.

Using observations of the 2011-Tohoku and some other tsunamis in rivers as a starting point for analytical and numerical exploration, this book suggests a basis for predicting tsunami impacts in a river after the wave has transitioned into the river’s channel.

This monograph is a compilation of a number of research studies presented in fourteen chapters dealing with the impact and restoration of coastal environments that have been affected by earthquakes and tsunamis. The focus is mainly on rivers, estuaries, coastal lagoons, beaches, and related ecosystems. In addition to direct impact and response due to flooding and subsequent abrasion, this publication covers physical, chemical and biological responses in coastal morphology, water quality and ecosystems and includes also topics dealing with risk reduction and vulnerability. This compilation mainly covers examples from large magnitude earthquake and tsunami events in the Indian and Pacific Ocean that are complemented with other events in Latin America and the Iberian Peninsula. Comprehensive descriptions of multi-scale impacts of tsunami and earthquake events, both spatially and temporally, will help the reader to understand the complicated interactions which occur in coastal zones in order to create a sustainable, resilient environment and achieve a society with smart post-event recovery planning. This book is aimed at researchers and students in coastal science and engineering as well as at policy makers, environmental planners and coastal managers.

This second edition reflects significant progress in tsunami research, monitoring and mitigation within the last decade. Primarily meant to summarize the state-of-the-art knowledge on physics of tsunamis, it describes up-to-date models of tsunamis generated by a submarine earthquake, landslide, volcanic eruption, meteorite impact, and moving atmospheric pressure inhomogeneities. Models of tsunami propagation and run-up are also discussed. The book investigates methods of tsunami monitoring including coastal mareographs, deep-water pressure gauges, GPS buoys, satellite altimetry, the study of ionospheric disturbances caused by tsunamis and the study of paleotsunamis. Non-linear phenomena in tsunami source and manifestations of water compressibility are discussed in the context of their contribution to the wave amplitude and energy. The practical method of calculating the initial elevation on a water surface at a seismotectonic tsunami source is expounded. Potential and eddy traces of a tsunamigenic earthquake in the ocean are examined in terms of their applicability to tsunami warning. The first edition of this book was published in 2009. Since then, a few catastrophic events occurred, including the 2011 Tohoku tsunami, which is well known all over the world. The book is intended for researchers, students and specialists in oceanography, geophysics, seismology, hydro-acoustics, geology, and geomorphology, including the engineering and insurance industries.

A theory is presented which describes the propagation of large amplitude Tsunamis across a basin of variable depth in the limit when this depth is varying slowly on a scale defined by the wavelength. In part I only the off-shore behavior is considered, in part II some features of the final run up are described. The technique used is to regard the wave as a slowly modulated simple wave with a slowly changing Riemann invariant. One of the most significant results is that over distances where the effect of depth variation modulates the amplitude of the wave, but does not disperse it, the variations of the amplitudes of the flow variables, such as maximum surface elevation, can be calculated as functions of the undisturbed depth without knowing how this depth varies in distance and without knowing the wave profile. These variations are fully calculated. (Author).

This volume presents a collection of contributions that were published in "Pure and Applied Geophysics - pageoph" and which deals with the major earthquake that hit Illapel, Chile on September 16, 2015 with magnitude 8.3, and associated trans-oceanic tsunami. The subducting Nazca plate beneath the Andes caused this major earthquake, generating strong shaking, permanent deformation, free oscillations of the Earth, and tsunamis. This event occurred in the flat-angle subducting segment of the plate.The generated tsunami spread throughout the entire Pacific Ocean and was recorded by numerous coastal tide gauges and open-ocean DART stations. All articles give an up-to-date account of research in one of the most active seismic zones worldwide. An introductory article by Kenji Satake rounds this collection off.

"Tsunamis, the giant waves that periodically engulf coastal areas and even the shores of lakes and rivers, have had a major impact on the world. Not only have they caused countless deaths, but have changed nations, societies and cultures from prehistoric to modern times. This book describes the science of tsunamis and the many ways they can be generated ranging from earthquakes, to volcanic eruptions and explosions, to landslides and others. It also explains how the waves travel across oceans at the speed of a jet airplane and how they focus or disperse their incredible energy. It delves into the clues that ancient tsunamis have left behind to be unraveled by modern science so that we can better understand not only what has happened in the past, but also what will happen in the future. The book also explores the human side of tsunami disasters looking at their effect on the residents of impacted communities by recounting the amazing true stories of survival, heroism and tragic loss. It discusses and provides examples of what works in mitigation, preparedness, warning, response and recovery from tsunamis, what doesn't work, and what needs to be done. It contains little-known stories about scientists struggling to better understand these catastrophic waves, while fighting government ignorance and reluctance to take action, as well as amazing chance discoveries, and the continued quest to learn more and become better prepared, as every year the odds of yet another catastrophic tsunami increase - It is not if, but when!"--

Earthquake-tsunamis, including the 2004 Indian Ocean Tsunami and the 2011 Tōhoku Tsunami in Japan, serve as tragic reminders that such waves pose a major natural hazard. Landslide-tsunamis, including the 1958 Lituya Bay case, may exceed 150 m in height, and similar waves generated in lakes and reservoirs may overtop dams and cause significant devastation. This book includes nine peer-review articles from some of the leading experts in the field of tsunami research. The collection represents a wide range of topics covering (i) wave generation, (ii) wave propagation, and (iii) their effects. Within (i), a tsunami source combining an underwater fault rupture and a landslide are addressed in the laboratory. Within (ii), frequency dispersion with the nonlinear shallow-water equations is considered and a detailed account of the 1755 Lisbon earthquake, tsunami, and fire in downtown Lisbon is presented. Two articles involve all three phases (i) to (iii), including runup and dam over-topping. Within (iii), a new semi-empirical equation for runup is introduced and the interaction of tsunamis with bridges and pipelines is investigated in large laboratory experiments. This state-of-the-art collection of articles is expected to improve modelling and mitigate the destructive effects of tsunamis and inspire many future research activities in this challenging and exciting research field.
