Conclusion

[18]  The data of observations in the Bay of Corinth indicate that, in the place of the landslide origin, water first receded from the shore and then returned, producing a run-up of 5-6 m. The numerical simulation of the tsunami wave run-up performed in this study showed that estimates obtained after the generation and propagation of the wave to the isobath x = -200 m agree well with observational data, thereby supporting the validity of the numerical schemes chosen in this study. Moreover, as was shown by Jiang and LeBlond [1993, 1994], who considered viscous and viscoplastic models of a landslide and solved this problem in a long-wave approximation for both the landslide and the generated wave, the generated wave first recedes from the shoreline at the initial time moment of the landslide movement, after which an elevation wave starts forming. Thus, the solution patterns obtained by Jiang and LeBlond [1993, 1994] and in our work are qualitatively similar; however, the analysis of the landslide movement in terms of an elastoplastic model, incorporating real data on sediments at the landslide origin and taking into account the strength reduction in the ground during the development of plastic deformations, provides the most correct (at present time) results of numerical simulation of tsunami wave generation and propagation and run-up values fitting better the available observational data.
