Asia-Pacific Region is an area with high risk of catastrophic natural disasters such as earthquakes, tsunami and volcanic eruptions. In today's highly globalized economy, when a disaster occurs it can create unpredictable turmoil not just in the affected area but, all over the world. Countermeasures against these large-scale disasters are crucial for the sustainable development of the global economy to ensure human security. 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.

After the 2011 Tohoku earthquake, more efforts for the prevention and reduction of the risks of natural disasters have been made all over the world. The G-EVER Consortium promotes activities in collaboration with international and national institutes and organizations as follows;

    1. Establishment of a framework for cooperation of research institutes and related organizations in the Asia-Pacific region working on seismic and volcanic disaster prevention
    2. Enhancement of exchange and sharing of various information on seismic and volcanic disaster prevention
    3. Building the international standard for the database, data exchange and disaster risk assessment

The 2nd G-EVER International Symposium and the 1st IUGS & SCJ International Workshop on Natural Hazards aim to encourage extensive discussions on the present situation of natural disaster mitigation from earthquake, tsunami, volcanic eruption and landslide in the Asia and Pacific regions, including (1) important research works and priorities to make strong resilience to our society, (2) ideal hazard maps which are essential to the society and Asia-Pacific scale hazard assessment activities, and (3) importance of contributions to solid earth science. Intensive discussions on next-decade mitigation processes to reduce the risks of natural hazards are encouraged.
