Symposium
Tsunami: generation and hazard

The 2004 Indian Ocean tsunami, the worst tsunami disaster in history, had a significant impact on
tsunami research, warning and hazard mitigation systems. To fully document the 2004 tsunami, IUGG
Tsunami Commission formed working groups to collect and compile field survey data, instrumental sea
level data and satellite data. Regional tsunami watch systems are being set up in basins and oceans in
the world with a guidance of UNESCO IOC. Tsunami hazard maps are implemented in many coastal
communities world-wide using the state-of-the-art numerical modeling techniques. Probabilistic tsunami
hazard assessments have been introduced in many coastal areas in the world. This joint session offers
forums for information exchange and discussion on such developments of tsunami research, particularly
after the 2004 Indian Ocean tsunami, as well as case studies of recent tsunamis. A part of this session
will be carried out as Workshop on Wave and water level data assessment and product development for
Tsunamis. Following the 2004 Indian Ocean Tsunami, the need for assessing the availability, quality,
access tools, archive, and analysis techniques of current and historic wave and water-level data for
tsunami event analysis became apparent. The objective of this workshop is to establish standard
procedures for data assessment and data archive for tsunami event analysis. The lessons learned from
this workshop and subsequent re-analysis of the data could apply to other extreme water level events.
