AbstractTsunamis are rare events with severe consequences. This generates a high demand onaccurate simulation results for planning and risk assessment purposes because of thelow availability of actual data from historic events. On the other hand, validation ofsimulation tools becomes very difficult with such a low amount of real-world data.Tsunami phenomena involve a large span of spatial and temporal scales—from oceanbasin scales ofto local coastal wave interactions oforeven, or from resonating wave phenomena with durations ofto rupture with time periods of. The scale gap of five orders ofmagnitude in each dimension makes accurate modelling very demanding, with anumber of approaches being taken to work around the impossibility of direct numericalsimulations. Along with the mentioned multi-scale characteristic, the tsunami wave hasa multitude of different phases, corresponding to different wave regimes and associatedequation sets. While in the deep ocean, wave propagation can be approximatedrelatively accurately by linear shallow-water theory, the transition to a bore or solitarywave train in shelf areas and then into a breaking wave in coastal regions demandsappropriate mathematical and numerical treatments. The short duration andunpredictability of tsunami events pose another challenging requirement to tsunamisimulation approaches. An accurate forecast is sought within seconds with very limited
