Interdisciplinary Tsunami Science

Session ID#: 159368

Session Description:
Tsunamis are one of the most devastating natural disasters, with the potential for inflicting tremendous damage along wide stretches of coastal areas. Recent tsunami events have demonstrated that the risk from tsunami hazards has grown tremendously since the devastating Pacific-wide tsunami of 1960. Expanding coastal populations and infrastructure will further increase tsunami risks and we still have a considerable way to go in our learning, education, and preparation around destructive tsunamis as evidenced by the catastrophic 2004 Indian Ocean event as well as the recent 2018 Sulawesi and Krakatau tsunamis. This session provides a broad forum for cross-disciplinary studies and invites contributions from all areas of tsunami science including: research; forecast and warning procedures; investigation of geologic records and hindcasting of past events; response, mitigation, and recovery strategies; databases of past observations; and hazard and risk studies from tsunamis generated by earthquakes, landslides, volcanic eruptions, meteorological phenomena, and meteorite impacts.
