Abstract
The key goals to studying submarine landslides and associated tsunamis are to better assess the magnitude
information of palaeo-tsunamis and to contribute to assessing future tsunami risks. The numerical modelling
of submarine landslides and the tsunamis thus generated comprises important interdisciplinary research that
requires knowledge of both geology and numerical modelling. Models are capable of delineating the time
evolution of tsunami hydrodynamics, sediment transport, and the resulting morphological changes associated
with deposition. To advance towards the ultimate goal of improved tsunami risk assessment, modellers and
geologists need to develop an in-depth mutual understanding of the advantages, limitations, and uncertainties
in both numerical modelling and geological records. In this work, seafloor features related to former submarine
landslides in the Alboran Sea basin have been identified through multibeam bathymetry data and high- to very
high-resolution seismic ...
