ABSTRACT: The objective of this paper is to compare the results obtained during the campaigns of seismic testing by MASW method and H/V-noise technique, made in the Damien’s plain (Port-au-Prince, Haiti). Both methods use the propagation of waves in the surface layers and identify the interfaces between the layers with impedance contrasts and/or important speeds. These contrasts are often the source site effects lithological. A connection between the frequency content of the wave indicated by H/V method and the shear-wave velocity indicated by MASW method is made according to the thickness of the layers. The comparison of these two types of results in the Damien’s plain (fundamental frequencies and shear- wave velocity) helps to improve the choice of estimation techniques site effects lithological, depending on the geophysical characteristics of the soil.
