Short summary
Short summary
This study presents a Probabilistic Tsunami Hazard Assessment for Stromboli, Italy, quantifying long-term risks from landslide-generated tsunamis. By combining new simulation databases with expert-derived probabilities, it introduces a method to model hazard uncertainty. Results show significant risk to coastal areas over 50 years, with high probabilities of inundation exceeding 0.5 m and notable chances of severe impacts at key locations.

Short summary
Short summary
Modelling tsunami generation due to a rapid submarine earthquake is a complex problem. Under a variety of realistic conditions in a subduction zone, we propose and test an efficient solution to this problem: a tool that can compute the generation of any potential tsunami in any ocean in the world. In the future, we will explore solutions that would also allow us to model tsunami generation by slower (time-dependent) seafloor displacement.

Short summary
The L-ML-HySEA (Landslide Multilayer Hyperbolic Systems and Efficient Algorithms) model of the tsunami triggered by the Storfjorden LS-1 landslide provides new insights into the sliding mechanism and bathymetry controlling the propagation, amplitude values and shoaling effects as well as coastal impact times. This case study provides new perspectives on tsunami hazard assessment in polar margins, where global climatic change and its related ocean warming may contribute to landslide trigger.
The L-ML-HySEA (Landslide Multilayer Hyperbolic Systems and Efficient Algorithms) model of the...
