The ongoing seismological research for the Central-Southern Aeolian Islands (CAVEAT project), Italy, from dense terrestrial seismic arrays

One of the tasks of the multidisciplinary project CAVEAT “Central-southern Aeolian islands: Volcanism and tEAring in the Tyrrhenian subduction system” was to deploy a dense seismic network composed by 120 wirelesss nodes, which were deployed for approximately 2 months on three islands of the Aeolian volcanic archipielago.

The main goals of this data acquisition are to:

• detect and locate the shallow weak seismicity related to both volcanic and tectonic activity,
• perform regional and local tomographic studies based on both passive methods and ambient noise cross-correlations (previously done for Lipari, Calò et al., 2023) to constrain the crust structure
• characterize the source mechanisms.

In this work we show the details of the data acquisition strategy and the preliminary analyses of the continuous ambient noise records, to reconstruct the shallow structure of the Aeolian Arc. This study is part of the INGV Pianeta Dinamico project 2023-2025 CAVEAT “Central-southern Aeolian islands: Volcanism and tEAring in the Tyrrhenian subduction system” (grant no.
