Abstract

This database, together with the one presented in de’ Michieli Vitturi et al. (2026), represents an update and extension of the dataset introduced in Cerminara et al. (2024). It contains a suite of numerical simulations of volcanic mass movement scenarios and the resulting tsunami generation, propagation, and inundation along the shores of Stromboli (Esposti Ongaro et al., 2021; 2025). All scenarios are computed using Multilayer-HySEA (Macías et al., 2021), a multilayer, depth-averaged, non-hydrostatic numerical model capable of simulating granular avalanche dynamics, their interaction with the sea, and the generation and propagation of water waves. The wave dispersion over complex bathymetries is captured by the shallow-water model by using 3 layers for the water phase.

In this database, we have used the same topo-bathymetry with 20 m resolution used in Cerminara et al. (2024). In detail, the combined topo-bathymetry consists of:

• Topography derived from a LiDAR (Light Detection And Ranging) survey carried out in May 2012 (MASE, 2013; Di Traglia et al., 2018);
• Bathymetry provided by the Marine Geohazards along the Italian Coasts (MaGIC) project (Chiocci and Ridente, 2011);

The two source datasets were standardized to a 10 m cell size, merged, and resampled to 20 m resolution (Fornaciai et al. 2019; 2024).

In total, simulations are done considering 13 landslides volumes, ranging from 0.5×10⁶ and 40×10⁶ m³, 11 vertical elevations from 500 m above to -580 m under the sea level and densities of 1667, 2000 and 2500 kg/m³ (i.e. density contrasts of 0.6, 0.5, and 0.4, with respect to water density). The original 198 scenarios of Cerminara et al. (2024) have been re-run utilizing new simulation settings, and complemented with 297 new scenarios, for a total of 495 scenarios.

For each scenario, maps of the maximum wave height above sea level, arrival times of the first positive peak, inundation height above the ground and water depth are provided, together with the waveforms at selected sampling points, including those of the two sensor-equipped buoys installed offshore the Sciara del Fuoco. A subset of the simulations of this database has been used to develop probabilistic tsunami inundation maps in de’ Michieli Vitturi et al. (submitted), whose approach of development has been described in Tadini et al. (submitted) and de’ Michieli Vitturi et al. (submitted). The simulations have been developed within the “Convenzione Attuativa per il potenziamento delle attività di servizio, Task 2.2” in the framework of “Accordo Quadro DPC-INGV 2022-2025”.
