Helen Crowley, GEM Secretary General, is set to be honoured with the prestigious Joyner Lecture Award for her distinguished contributions to earthquake science and engineering communication. She will deliver her lecture on April 10th, 2024 at 4:00 PM, Wednesday at the EERI Annual Meeting in Seattle, Washington; on May 2nd at 6:00 PM, 2024 at the SSA Annual Meeting in Anchorage, Alaska; and on July 4th at the 18th WCEE2024. Lecture day: Thursday July 4th, 17:00 - 18:00 Lecture title: Why seismic hazard modelling has become a risky business

Strong tsunamis are low-probability and high-consequence events. They are usually triggered by large subduction earthquakes, such as the 2004 Indian Ocean event. They can also be caused by complex cascades, such as flank collapse caused by the 2018 Anak Krakatau volcanic eruption and the 2018 Sulawesi submarine landslides triggered by a large strike-slip earthquake. They cause havoc and destruction along their paths and can have severe impacts and consequences on communities very far from their points of origin. Tsunami research is a perfect example of inter- and trans-disciplinary collaboration. There are major research challenges that make it an extremely vibrant and stimulating field: gaps in coverage of historical data and use of paleo-seismic and tsunami data, physics-based modelling of tsunami genesis and propagation, modelling of structural response to tsunami waves, loss and consequence modelling, the need for high-performance computing and simulations, uncertainty treatment in tsunami risk assessments, issuing timely warning, complexities related to modelling of human response to tsunami, and the central role of communication and capacity building. The physical sciences and engineering community can contribute significantly towards addressing these challenges. This technical section will welcome contributions across various aspects of tsunami risk engineering in a broad and inter-disciplinary sense: probabilistic tsunami hazard and risk analysis, modelling physical consequences of tsunami on buildings, infrastructure, and industrial facilities, tsunami resistant design in codes, design of vertical evacuation structures, experimental testing of tsunamis, damage-dependent fragility assessment, tsunami vulnerability and loss assessment, digital twins of tsunami and its consequences, physical countermeasures, tsunami early warning and impact forecasting, tsunami evacuation modelling, financial measures for tsunami preparedness, and tsunami risk communication.
