Abstract
Two variants of a method based on the Backus-Gilbert approach have been used for mapping phase velocities of Rayleigh waves for Western Europe. The results are quite stable and in good agreement with those of previous investigations. The data for Central Europe seem to be consistent also with the presence of some anisotropy in the proximity of the crust-mantle transition.
Riassunto
Viene illustrata ľapplicazione, alľEuropa Occidentale, di due varianti di regionalizzazione automatica delle velocità di fase di onde di Rayleigh. I risultati sono stabili ed in accordo con quelli di ricerche precedenti. Dallo studio è emersa la presenza di anisotropia, in prossimità della transizione crosta-mantello in Europa Centrale; la direzione delľasse di massima velocità ben si accorda con ľandamento del Graben del Reno.
