Data sets

La Palma landslide tsunami: computation of the tsunami source with a calibrated multi-fluid Navier-Stokes model and wave impact assessment with propagation models of different types S. Abadie, A. Paris, R. Ata, S. L. Roy, G. Arnaud, A. Poupardin, L. Clous, P. Heinrich, J. Harris, R. Pederos, and Y. Krien https://doi.org/10.17882/61301

Short summary

The tsunami which could be generated by a potential flank collapse of the Cumbre Vieja volcano in La Palma, Canary Islands, is evaluated through a numerical simulation based on an advanced and finely calibrated model. Then the consequences of such an event for Europe, France and Guadeloupe island are investigated using different numerical models for propagation. The impacts vary from negligible to very significant depending on the location considered.
