Tsunamis and hurricanes are natural catastrophes which can make cons- erable material damage and personal harm to humans. Any possibility to describe these phenomena and to ?nd methods of predictability of any kind seem therefore to be of interest not only for meteorologists, but also for governments, evacuation plans or the insurance industry etc. There may now exist a chance to satisfy these needs, if a tsunami wave equation could be found and solved. Seismic waves in the Earth's crust propagate faster (4-6 km/sec) than tsunamis (100-900 km/h). This speed di?erence allows an early warning time of up to a few hours, depending on the location of the earthquake or underwater explosion. If a tsunami wave equation and its solutions were known, even a guess of the tsunami crest height might be possible and useful. In this book a mathematical approach to tsunami wave equations is p- sented. To the author's knowledge some of the tools and computer codes presentedherehavenever beenappliedontsunamisandhurricanes. Someof the calculations in this book are based on thePreiswerk-Landau equ- alence principle between gasdynamics and hydrodynamics as well on the Bechert-Marx linearization method using the mass variable transfor- tion. Other tools used here are similarity transformations and the program packet Mathematica by Wolfram. Although knowledge of these codes is not necessary for the use of this book, it may however help to understand some calculations and the reader may acquire some knowledge of this p- gram.

‘Cap’s book establishes Proximization Theory firmly as a central methodological and theoretical focus of Critical Discourse Analysis. It provides a coherent framework and exemplary case studies for the analysis of persuasion through intimidation, which go far beyond traditional approaches to this crucial area of public discourse. It is essential reading not just for linguists but also for psychologists and social and political scientists.’ — Andreas Musolff, Professor, University of East Anglia, UK This book investigates linguistic strategies of threat construction and fear generation in contemporary public communication, including state political discourse as well as non-governmental, media and institutional discourses. It describes the ways in which the construction of closeness and remoteness can be manipulated in the public sphere and bound up with fear, security and conflict. Featuring a series of case studies in different domains, from presidential speeches to environmental discourse, it demonstrates how political and organizational leaders enforce the imminence of an outside threat to claim legitimization of preventive policies. It reveals that the best legitimization effects are obtained by discursively constructed fear appeals, which ensure quick social mobilization. The scope of the book is of immediate concern in the modern globalized era where borders and distance dissolve and are re-imagined. It will appeal to students and researchers in linguistics, discourse analysis, media communication as well as social and political sciences. Piotr Cap is Professor of Linguistics at the University of Łódź, Poland. His interests are in pragmatics, critical discourse studies, political linguistics and genre theory. His publications include Perspectives in Politics and Discourse (2010),Proximization: The Pragmatics of Symbolic Distance Crossing (2013), Analyzing Genres in Political Communication (2013) andContemporary Critical Discourse Studies (2014). He is Managing Editor of International Review of Pragmatics.
