Abstract

Data corresponding to tsunami sources of potential La Palma collapse scenario for slide volumes of 20, 40, 80, and 450 km3.  The initiation of the slide is modeled using THETIS, a 3D Navier-Stokes model.  The slide is considered as a Newtonian fluid whose viscosity is adjusted to approximate a granular behavior.  After 5 minutes of propagation with THETIS, the generated water wave is transferred into FUNWAVE-TVD for 15 minutes fo Boussinesq model simulation.  Wave elevation and water velocity at this point in time, 20 minutes after the start of the flank collapse, are provided.
