Goals Clausole campione

Goals. The general objective is the study of the anisotropy of the seismic waves propagation, investigating the spatial and the temporal variation of the attenuation parameters in central Italy. The ambition of this project is to provide useful data to reach the complete regionalization of seismic motion, especially in central Italy, where the geomorphological context is very complex, due to the presence of multiple faults alignments, variable geological units and local site conditions very different within narrow areas. The intermediate goals are: 1. To compile a dataset of spectral amplitudes in central Italy for P and S waves, including the metadata relative to the events and the recording stations; 2. To improve the inversion techniques both following parametric and non-parametric approaches to compute source, attenuation and site terms and their spatial variability; 3. To apply the inversion methods to explore the azimuthal and temporal attenuation properties in central Italy, in terms of quality factor Q and high-frequency decay kappa.
