Tsunamis are one of the most devastating natural disasters, with the potential to cause tremendous damage along coastlines around the world. Catastrophic tsunami events of this century, such as the 2004 Indian Ocean and 2011 Tohoku tsunamis, have demonstrated the increasing risk of disasters for coastal population and infrastructure. As a response to these deadly tsunamis, many new tsunami forecast and warning capabilities have been developed and implemented. The 2018 Sulawesi and Krakatau tsunamis have demonstrated that tsunamis caused by mechanisms other than great earthquakes must also be considered. The more recent 2022 large volcanic eruption in Tonga generated air-sea coupled wave causing damage along the coast around the Pacific. Sea-level rise caused by global warning also presents new challenges for tsunami science. The IUGG symposium will discuss all aspects of tsunami science including: theoretical and numerical research on tsunami generation and inundation; development of forecast and warning methods; investigation of geologic records of past events; response, mitigation, and recovery strategies; observational studies, including collation of historical observations; and hazard and risk studies from tsunamis generated by earthquakes, landslides, volcanic eruptions. The symposium will also include a special session on meteo-tsunamis, including the air-sea coupled wave due to the 2022 Tonga eruption, in association with IAMAS.
