After the recent devastating tsunami in southern Asia, I tried to find a simple way to present the physics of this phenomenon to students—in particular, the origin of the dispersion relation and the consequent wave properties. Being unable to locate a suitable source for a truly elementary approach, I developed the simple derivation presented here by extending to shallow-water waves a clever capillary wave model recently developed by Behroozi and Podolefsky (2001 Eur. J. Phys. 23 225). The main… Expand

Understanding the tsunami with a simple model
In this paper, we use the approximation of shallow water waves (Margaritondo G 2005 Eur. J. Phys. 26 401) to understand the behaviour of a tsunami in a variable depth. We deduce the shallow water… Expand
Alternative tsunami models
The interesting papers by Margaritondo (2005 Eur. J. Phys. 26 401) and by Helene and Yamashita (2006 Eur. J. Phys. 27 855) analysed the great Indian Ocean tsunami of 2004 using a simple… Expand
Introduction to the Physics of Waves
TLDR
This textbook introduces the physics of wave phenomena in a refreshingly approachable way, making it ideal for first- and second-year undergraduate students in the physical sciences. Expand
Hydrodynamics and loadings of tsunami waves with different fluid characteristics: Newtonian & non-Newtonian
Tsunamis are impulsively generated waves which may severely damage structures within the coastal zones. Damage may occur to protective structures, port and waterfront facilities, and commercial and… Expand
Tsunami: a history of the term and of scientific understanding of the phenomenon in Japanese and Western culture
TLDR
This book uses Japanese and Western sources to document historical tsunami in Europe and Japan, the birth of the scientific understanding of tsunami, and how the Japanese term came to be adopted in English. Expand
Tsunami Propagation Models Based on First Principles
Abstract : Tsunamis are ocean waves generated by the displacement of a large volume of water due to earthquakes, volcanic eruptions, landslides or other causes above or below the ocean floor (e.g.,… Expand
The Physics of Tsunami: Basic understanding of the Indian Ocean disaster
This study gives a simple physics explanation behind the Indian Ocean earthquake, called December 26 th 's Tsunami. The explanation based on physics energy conservation and wave properties have been… Expand
A HISTORY OF THE TERM AND OF SCIENTIFIC UNDERSTANDING OF THE PHENOMENON IN JAPANESE AND WESTERN CULTURE by
In the past few years we have unfortunately had several reminders of the ability of a particular type of ocean wave—a tsunami—to devastate coastal areas. The Indian Ocean tsunami of 2004, in… Expand
The Physics of Tsunami: Basic understanding of the Indian Ocean disaster
TLDR
This study gives a simple physics explanation behind the Indian Ocean earthquake, called December 26th‘s Tsunami, based on physics energy conservation and wave properties. Expand
Wavelet-based multifractal analysis of nonlinear time series: the earthquake-driven tsunami of 27 February 2010 in Chile.
TLDR
This work analyzes an empirical time series of tidal gauge from the tsunami event of 27 February 2010 in Chile and studies a numerical solution of the driven-damped regularized long-wave equation (RLWE), suggesting a correspondence between the pre- and post-tsunami states and the on state in the RLWE.
