The GITANES software package allows an effective application of the Generalized Inverse Technique (Andrews, 1986) in the MATLAB environment for the joint evaluation of the source spectra and site spectral amplification using earthquake waveforms collected by a network of stations. The package includes a GUI, which allows the user to have a rapid visual overview of the available data, and an immediate insight in the corresponding results, when applying changes to the propagation model and to the selection of stations and events.
As it is provided, the GITANES package is equally suitable for site amplification surveys intended for microzonation studies as well as for studies regarding the spectrum of the seismic source.
