Earthquake Hazards and Mitigation
Earthquake Hazards and Mitigation
About this eBook
Preface We have the great pleasure in welcoming all the participants to the International Workshop on Earthquake Hazards and Mitigations EHAM-2007 on December 7 and 8, 2007 in Guwahati, India. It is needless to emphasize again the importance of carrying out investigation and research on prediction of earthquake hazards and finding out appropriate mitigation measures. The extent of damage caused by the various earthquake related hazards occurred in historical time to the recent time are self explanatory. Extensive research is being carried out on prediction of earthquake hazards and its mitigations at global national regional levels in the last few decades. Several seminars, symposiums, workshops and conferences are being organized at national and international levels regularly to share recent experiences and research findings among the academicians, design consultants and practicing engineers. However, every earthquake teaches a new lesson causes severe problems and imposes new challenge, thus driving us to pursue the research on finding the solutions to these problems and challenges. Organization of workshops, symposiums, seminars and conferences on a regular basis on the field of earthquake engineering and allied areas is essential to exchange the present state-of-the-art and to promote recent and advanced technologies in mitigating earthquake hazards. Thus, we have the theme of the workshop as Earthquake Hazards and Mitigations . The objective of this workshop is to 1 bring together people from all spheres to exchange knowledge and discuss the new developments in the field of earthquake engineering and allied areas, 2 exchange information about present state-of-the-art and current practice adopted globally in prediction and mitigation of earthquake hazards, and 3 explore novel and innovative methods for prediction and mitigation of hazards considering the future earthquakes for building sustainable safe infrastructures and ensuring safety of community. It is expected that this workshop will contribute towards achieving these objectives through the exchange of information and ideas among the international scientific and research community. The themes covered broadly in this workshop are 1 Engineering Seismology and Seismic Hazards 3 Geotechnical Earthquake Engineering 4 Structural Earthquake Engineering 5 Other related issues Under these broad themes, several sub-topics related to estimation of structural and geotechnical hazards caused by earthquake and their mitigation methods are covered in the workshop. There has been an overwhelming response to our call for papers from all over the world. The workshop committee has been delighted at the number of interesting and stimulating papers that have been received. In this workshop, five keynote lectures and twelve invited lectures will be delivered by distinguished scholars and experts in this field. Another major attraction will be a panel discussion comprising of experts in different allied areas from various countries. Apart from keynote invited lectures a total of 44 papers submitted from various countries will be presented in total of six technical sessions conducted in parallel sessions of two. This workshop is held under the auspices of the Indian Institute of Technology Guwahati in association with Asian Technical Committee ATC-3 on Geotechnology for Natural Hazards and Technical Committee TC4 on Earthquake Geotechnical Engineering and Associated Problems of International Society of Soil Mechanics and Geotechnical Engineering. We would like to express sincere gratitude to both the organizations for their strong technical support.
The committee is looking forward to a very successful and convivial event for all participants. It is
