Caratterizzazione sismico-deposizionale della fascia pedemontana orientale della provincia di Treviso

The aim of this thesis is to analyze and develop the relationships between architecture depositional surface of Quaternary deposits and characteristics Rayeigh's spectral waves, which measured with geophysical technique ReMi (Refraction Microtremors). The fundamental mode of vibration of Rayleigh waves was compared with the local geological model reconstructed by mechanical and manual drilling, surface take over and other geophysical measurements. The study area, which located in the upper province of Treviso, cover the municipalities of Cordignano territory, Godega di Sant'Urbano, Orsago and San Fior. This area was affected by tectonics Alpine and evolution of the Veneto-Friuli plain during pre- and post-LGM. The study was showed that in most cases the types of deposit have specific signatures spectral and well defined. The spectral form, under controlled conditions, can be used as a marker of particular depositional architectures. The spectrum measurement is quick, inexpensive, and the technique can therefore be applied to the analysis in large areas. This can introduce a new correlation three-dimensional about morpho-sedimentary units and an immediate effect on seismic micro-zoning studies, which can benefit from this new knowledge in the definition of the seismic response.
