Natural Disasters: Tsunamis

The Indian Ocean Tsunami

On December 26, 2004, a massive tsunami triggered by an underwater earthquake pummeled the coasts of Thailand, Indonesia, Sri Lanka, and other countries along the Indian Ocean. With casualties as far away as Africa, the aftermath was overwhelming: ships could be spotted miles inland; cars floated in the ocean; legions of the unidentified dead-an estimated 225,000-were buried in mass graves; relief organizations struggled to reach rural areas and provide adequate aid for survivors. Shortly after this disaster, researchers from around the world traveled to the regions most devastated areas, observing and documenting the tsunamis impact. The Indian Ocean Tsunami: The Global Response to a Natural Disaster offers the first analysis of the response and recovery effort. Editors Pradyumna P. Karan and S. Subbiah, employing an interdisciplinary approach, have assembled an international team of top geographers, geologists, anthropologists, and political scientists to study the environmental, economic, and political effects of the 2004 Indian Ocean tsunami. The volume includes chapters that address the tsunamis geo-environmental impact on coastal ecosystems and groundwater systems. Other chapters offer sociocultural perspectives on religious power relations in South India and suggest ways to improve government agencies response systems for natural disasters. A clear and definitive analysis of the second deadliest natural disaster on record, The Indian Ocean Tsunami will be of interest to environmentalists and political scientists alike, as well as to planners and administrators of disaster-preparedness programs.

Physics of Tsunamis

Till the very end of the twentieth century tsunami waves (or 'waves in a harbour', translated from Japanese) were considered an extremely rare and exotic natural p- nomenon, originating in the ocean and unexpectedly falling upon the seaside as gigantic waves. The 26th of December 2004, when tsunami waves wiped out, in a single day, more than 250,000 human lives, mourned in many countries, turned out to be a tragic date for all mankind. The authors of this book, who have studied tsunami waves for many years, - tended it to be a systematic exposition of modern ideas concerning * The mechanisms of tsunami wave generation * The peculiarities of tsunami wave propagation in the open ocean and of how waves run-up beaches * Methods for tsunami wave registration and the operation of a tsunami warning system * The mechanisms of other catastrophic processes in the ocean related to the se- mic activity of our planet The authors considered their main goal to be the creation of book prese- ing modern knowledge of tsunami waves and of other catastrophes in the ocean to scienti?c researchers and specialists in geophysics, oceanography, seismology, hydroacoustics, geology, geomorphology, civil and seaside engineering, postgr- uate students and students of relevant professions.
