The year 2010 is the 50 year anniversary of the 1960 Chilean Tsunami generated by a giant earthquake offshore Chile (M=9.5),
which caused severe damage in many countries along the Pacific Ocean. After the tsunami, understanding of tsunami generation
mechanisms, development of international warning systems, and integrated management became important issues in high-tsunami-risk
countries for future disaster mitigation. Since then, tsunami-related science and technology have been developed to overcome
those issues and have contributed to producing safe societies. However, similar tragedies such as the 2004 Indian Ocean tsunami,
have been repeated in different areas of the world. Now is the time to share data, experiences, and tsunami-associated issues
for disaster mitigation against future tsunamis. For this purpose, we organized the 3rd ITFS in Sendai, Japan. The major topics
of the symposium are the following.
