FURTHER - The role of FlUids in the pReparaTory pHase of EaRthquakes in Southern Apennines (collaboration)
We are collaborating on the FURTHER project with colleagues at INGV. The project PI is Francesca Di Luccio at INGV, Rome. The overarching goal of this project is to investigate the role of fluids in the preparatory phase of earthquakes in the Southern Apennines, Italy. The group aims to study the pathway of fluids from the source to the upper crust where major earthquakes occur, using a cross-disciplinary approach that includes seismological, geochemical, geodetic and geospace data. The interplay of fluids, shallow and deep-seated active structures and seismicity will be explored at the local and regional scales, including imaging the seismic structure beneath the Southern Apennines. We are contributing to the structural imaging by using receiver functions (RFs) computed from recordings at broadband stations in the region. We offer an update to previous results for the region by modeling the receiver functions to obtain the best multi-layer seismic velocity structure (VP, VS, VP/VS, thickness, and anisotropic/dipping structures) for the crust. Our initial station selection is shown in the map below.
