Pages: 140, Feb. 22, 2012 Copyright 2012 by the Geological Survey of Japan Preface As shown by the 2011 off the Pacific coast of Tohoku Earthquake, Asia-Pacific Region is an area with high risk of catastrophic natural disasters such as earthquakes and volcanic eruptions. Once a disaster occurs, in today's highly globalized economy, it can create unpredictable turmoil all over the world, not just in the affected area. These global-scale disasters are crucial for the sustainable development of the global economy to ensure human security. Japan is a country of plate convergence. Since the 1995 Hyogoken-Nanbu (Kobe) earthquake, extensive studies have been done in Japan, such as nation wide active fault surveys, development of high density seismograph networks and GPS crustal deformation monitoring system. Our knowledge on earthquakes is improved dramatically and observation and study results are systematically transferred to the society. However, it is fare to say that our understanding on earthquakes is still limited and farther studies should be done for the mitigation of seismic disasters. One of impediments to the development of geologic hazard studies is the infrequency of occurrence in a limited area. This makes it difficult to promote hypothesis and test processes. This may be solved by the international correlational study because geologic hazards are not less frequent phenomena any more. Now is the time to establish an effective international framework where we collaborate and develop a system to gather information on disaster mitigation in Asia-Pacific Region, including Japan. Here are the purposes of the workshop. 1) To enhance collaboration among geological institutes within the Asian Circum-Pacific Region and rearrange existing information about the future risk for global earthquakes and volcanic disasters, 2) to build international and national networks, set up a website, and establish a consortium so that we can share and provide the information, 3) to create the environment to promote cooperative research, including personnel training, in the area with little information, especially in developing countries, and 4) to evaluate the risk of business activities in the Asia-Pacific region and seek to develop new business opportunities to provide information on the risk of catastrophic natural disasters. Through this full research of natural disasters, we can contribute to the society. Grasping disaster risk in advance enables us to reduce the damage from large-scale disasters, which are expected to cause worldwide impact on the economy. By improving the database for hazard risk information, we can assist international economic activities in formulating their BCP, and various private businesses concerning risk reduction, non life insurance.
