GNGTS 2024 - Atti del 42° Convegno Nazionale

Session 2.1 GNGTS 2024 A future perspective of this work could be to extend the method into different tectonic contexts (e.g. 2019 Ridgecrest earthquake sequence, on a strike-slip fault domain) where we have a huge amount of recordings available and different styles of faults. Acknowledgements We are very grateful to Prof. Daniele Spallarossa (University of Genoa, Italy) for making available the dataset used in this work and to Prof. Franti š ek Gallovi č (University of Prague, Czech Republic) for the fruitful discussion about this work. This research is supported by the Italian Ministry of University and Research (MIUR) in the frame of the project SECURE: "Regional-Scale Earthquake Ground Motion PrediCtions ThroUgh Pyhsics-based and EmpiRical ApproachEs: A Case study Central Italy".
