Much of the research behind these guidelines has been based on the physical modelling of waves generated by traditional paddle generators, capable only of producing short-waves. Short-waves are not necessarily physically representative of tsunami, and research has so far been limited to a few facilities worldwide. A long-wave generator capable of testing at large-scale has been developed in collaboration between UCL and HR Wallingford, in part to address this shortcoming. This paper presents a review of tsunami research and guidance to date and uses data from experiments carried out using a pneumatic long-wave generator to compare and contrast with design equations in literature. The longer wavelengths generated by our test facility will extend the existing research, providing a more representative platform for improved tsunami design guidance in the ...

We seek common avenues of research and points of contact among the existing philosophies used in these four different fields in the context of multi-hazard assessment frameworks. In essence, this is a step towards the identification of a common underlying structure between different fields that will allow the future unification of vulnerability methodologies under a single framework.
