Tsunami Science Four Years After the 2004 Indian Ocean Tsunami


Book Description

The tragedy of the 2004 Indian Ocean tsunami has led to a rapid expansion in science directed at understanding tsunami and mitigating their hazard. A remarkable cross-section of this research was presented in the session: Tsunami Generation and Hazard, at the International Union of Geodesy and Geophysics XXIV General Assembly in Perugia, held in July of 2007. Over one hundred presentations were made at this session, spanning topics ranging from paleotsunami research, to nonlinear shallow-water theory, to tsunami hazard and risk assessment. A selection of this work, along with other contributions from leading tsunami scientists, is published in detail in the 28 papers of this special issue of Pure and Applied Geophysics: Tsunami Science Four Years After the Indian Ocean Tsunami. Part I of this issue includes 14 papers covering the state-of-the-art in tsunami modelling and hazard assessment. Another 14 papers are published in Part II focusing on observations and data analysis.




The Indian Ocean Tsunami


Book Description

The Indian Ocean tsunami of December 2004 is considered to have been one of the worst natural disasters in history, affecting twelve countries, from Indonesia to Somalia. 175,000 people are believed to have lost their lives, almost 50,000 were registered as missing and 1.7 million people were displaced. As well as this horrendous toll on human life




Weathering the World


Book Description

The Asian tsunami in December 2004 severely affected people in coastal regions all around the Indian Ocean. This book provides the first in-depth ethnography of the disaster and its effects on a fishing village in Tamil Nadu, India. The author explores how the villagers have lived with the tsunami in the years succeeding it and actively worked to gradually regain a sense of certainty and confidence in their environment in the face of disempowering disaster. What appears is a remarkable local recovery process in which the survivors have interwoven the tsunami and the everyday in a series of subtle practices and theorisations, resulting in a complex and continuous recreation of village life. By showing the composite nature of the tsunami as an event, the book adds new theoretical insight into the anthropology of natural disaster and recovery.




The Indian Ocean Tsunami


Book Description

December 2004, a tsunami swept over the coasts of Indonesia, Sri Lanka, India, Thailand, and other South Asian countries, leaving hundreds of thousands dead and many more without the resources to rebuild their lives. 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 deadùan estimated 225,000ùwere buried in mass graves; relief organizations struggled to reach rural areas and provide adequate aid to survivors. The Indian Ocean Tsunami: The Global Response to a Natural Disaster is the first comprehensive assessment of the environmental, social, and economic costs of this tragedy. Soon after the tsunami, an international team of geographers, geologists, anthropologists, and political scientists traveled to the most damaged areas to observe and document the tsunami's impact. The Indian Ocean Tsunami draws on data collected by this team. Editors Pradyumna P. Karan and Shanmugam P. Subbiah, along with contributors from multiple disciplines, examine numerous issues that arose in the aftermath of the tsunami, such as inequities in response efforts, unequal distribution of disaster relief aid, and relocation and housing problems. The Indian Ocean Tsunami is organized into several sections, the first of which deals with the ecological destruction of the tsunami. It includes case studies and photographs of the damage in Japan, Indonesia, South India, and other areas. The second section analyzes the economic and social aspects of the aid responses, specifically discussing the role of NGOs in tsunami relief, the strengths and weaknesses of the reconstruction process, and the lessons the tsunami offers to those who are responsible for dealing with future disasters. In the tsunami's aftermath, the inadequacies of governmental and privately funded aid and the challenge of rehabilitating devastated ecosystems quickly became apparent. With this volume, Karan and Suhbiah illuminate the need for the development of efficient, socially and environmentally sustainable practices to cope with environmental disasters. They suggest that education about the ongoing process of recovery will mitigate the effects of future natural disasters. Including maps, photographs, and statistical analyses, The Indian Ocean Tsunami is a clear and definitive evaluation of the tsunami's impact and the world's response to it.




Tsunami Warning and Preparedness


Book Description

Many coastal areas of the United States are at risk for tsunamis. After the catastrophic 2004 tsunami in the Indian Ocean, legislation was passed to expand U.S. tsunami warning capabilities. Since then, the nation has made progress in several related areas on both the federal and state levels. At the federal level, NOAA has improved the ability to detect and forecast tsunamis by expanding the sensor network. Other federal and state activities to increase tsunami safety include: improvements to tsunami hazard and evacuation maps for many coastal communities; vulnerability assessments of some coastal populations in several states; and new efforts to increase public awareness of the hazard and how to respond. Tsunami Warning and Preparedness explores the advances made in tsunami detection and preparedness, and identifies the challenges that still remain. The book describes areas of research and development that would improve tsunami education, preparation, and detection, especially with tsunamis that arrive less than an hour after the triggering event. It asserts that seamless coordination between the two Tsunami Warning Centers and clear communications to local officials and the public could create a timely and effective response to coastal communities facing a pending tsuanami. According to Tsunami Warning and Preparedness, minimizing future losses to the nation from tsunamis requires persistent progress across the broad spectrum of efforts including: risk assessment, public education, government coordination, detection and forecasting, and warning-center operations. The book also suggests designing effective interagency exercises, using professional emergency-management standards to prepare communities, and prioritizing funding based on tsunami risk.




Tsunami Science Four Years After the 2004 Indian Ocean Tsunami


Book Description

The 2004 Indian Ocean tsunami was triggered by a 9. 15 magnitude earthquake (MELTZNER et al. , 2006; CHLIEH et al. , 2007) that occurred at 0:58:53 GMT, 7:58:53 LT (USGS) (t ). The epicenter was located at 3. 3 N, 95. 8 E (Fig. 1) with a focal depth of EQ approximately 30 km. The earthquake was responsible for a sudden fault slip estimated on average from 12–15 m (SYNOLAKIS et al. , 2005; LAY et al. , 2005) to 20 m (FU and SUN, 30 2006). The seismic moment estimate (Mo = 1. 3 5 9 10 dyne-cm), based on the Figure 1 Locations of video recordings, recovered clocks, and reliable eyewitness observations. 1: Coastal plains ?ooded by the tsunami; 2: non-?ooded coastal plains; 3: uplands. Insert 3D-map showing the Sumatra Island, the studied area, and the epicenter of the 26/12/2004 earthquake. The video taken at Uteuen Badeue, on the eastern edge of the Banda Aceh Bay, was recorded by the chief of the Fishery Regional Of?ce from the top of a cliff. The movie that was shot near the Baiturrahman mosque in downtown Banda Aceh has been shown worldwide on TV. The one at Peukan Bada has been recorded during a wedding party. The last two movies were analyzed in detail in order to calculate the tsunami velocity (FRITZ et al. , 2006). Vol.




The Orphan Tsunami of 1700


Book Description

A puzzling tsunami entered Japanese history in January 1700. Samurai, merchants, and villagers wrote of minor flooding and damage. Some noted having felt no earthquake; they wondered what had set off the waves but had no way of knowing that the tsunami was spawned during an earthquake along the coast of northwestern North America. This orphan tsunami would not be linked to its parent earthquake until the mid-twentieth century, through an extraordinary series of discoveries in both North America and Japan. The Orphan Tsunami of 1700, now in its second edition, tells this scientific detective story through its North American and Japanese clues. The story underpins many of today�s precautions against earthquake and tsunami hazards in the Cascadia region of northwestern North America. The Japanese tsunami of March 2011 called attention to these hazards as a mirror image of the transpacific waves of January 1700.

The Indian Ocean Tsunami Of 2004


Book Description

On December 26, 2004, a gigantic earthquake ripped apart the floor of the Indian Ocean off the coast of Sumatra. The force of the quake sent a tsunami in all directions toward unprotected shores and unwarned populations, many in remote areas or secluded vacation spots. Within 12 hours, more than 200,000 people had been killed, and many more left injured or homeless, their livelihoods destroyed. Cities and villages lay in ruins. Even the geography of the earth was changed. But as the affected countries, with help from around the world, struggled to recover, scientists warned that the next deadly tsunami could come at any time. The question remains whether the world will be any more prepared for the next one. Read how the Indian Ocean earthquake and tsunami changed the way nations are tracking natural-disaster warnings in an effort to prevent future disasters.
