The application of simulation software has proven to be a crucial tool for tsunami hazard
assessment studies. Understanding the potentially devastating effects of tsunamis leads to the
development of safety and resilience measures, such as the design of evacuation plans or the planning
of the economic investment necessary to quickly mitigate their consequences. This article introduces
a pseudo-probabilistic seismic-triggered tsunami simulation approach to investigate the potential
impact of tsunamis in the southwestern coast of Spain, in the provinces of Huelva and Cádiz. Selected
faults, probabilistic distributions and sampling methods are presented as well as some results for the
nearly 900 Atlantic-origin tsunamis computed along the 250 km-long coast.This work has being carried out under a project funded by a public mutual agreement of
understanding between the CN-IGME (CSIC) and the CCS (Law reference: BOE 103, 30/04/2019).
This project is supported by an agreement of understanding between CN-IGME and UMA, creating a
cooperative entity INGEA (Law reference: BOE 332, 22/12/2020). The numerical results presented in
this work have been performed with the computational resources allocated by the Spanish Network
for Supercomputing (RES) grants AECT-2020-3-0023 and AECT-2021-2-0018. Further support has also
been received from the Spanish Government research project MEGAFLOW (RTI2018-096064-B-C21)
and ChEESE project (EU Horizon 2020, grant agreement No. 823844, https://cheese-coe.eu/) due to
the synergies found between the projects. Partial funding for open access charge: Universidad de Málag
