Tsunamis can produce catastrophic damage on vulnerable coastlines, essentially following major earthquakes, landslides or atmospheric disturbances. After the catastrophic events in 2004 and 2011, tsunami science has grown significantly, opening new fields of research for various domains, and also for specific regions where the tsunami hazard was underestimated. While tsunami modeling is essential to quantify possible hazard scenarios, based on numerical models or laboratory experiences, it is essential to rely on complete databases of past observations, including results of paleotsunami investigations. Furthermore a robust hazard analysis has to take into account uncertainties and probabilities with the more advanced approaches. The vulnerability of populations, of infrastructures and of the built environment in coastal zones increases everywhere, therefore integrated plans for tsunami risk prevention and mitigation should be encouraged in any exposed coastline, consistent with the procedures now in place in a growing number of Tsunami Warning System. The NH5.1/OS2.12/SM 3.07 Tsunami session welcomes contributions covering any of the aspects mentioned here, encompassing field data, regional hazard studies, observation databases, numerical modeling, risk studies, real time networks, operational tools and procedures towards a most efficient warning.
A focus on recent tsunami events all over the globe (Kos, Bodrum, Mexico) is encouraged, as well as on the achievements of recent research projects.
