Working Program Clausole campione

Working Program. The project is organized in three working tasks Task 1: Dataset The aim of this task is to build a dataset of ▇▇▇▇▇▇▇ spectral amplitude for P and S waves in central Italy, using seismic data recorded since 2008 with magnitude M > 2.5. The spectra will be provided as-recorded (NS-WE and UP components) and rotated in the directions useful to investigate the spatial variability. The dataset will also include information concerning the events and the recording stations, collected from the INGV databases and from recent publications available in the literature. This activity will be carried out in cooperation with ▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇▇▇▇ from Genoa University and associated to the INGV. The dataset will be subjected to a sanity check to exclude noisy and anomalous records and optimized the spatial coverage. Task 2: Inversion codes The aim of this task is to develop a common software to perform spectral inversions, adopting both parametric and non-parametric approaches. The software will be realized in Matlab language by INGV, translating the routines developed in CICESE and will be compatible with the data format of the flat-file of Task1. Several tests will be performed to investigate the pros and cons of using the two approaches in estimating ground motion spectral parameters.
