Multichannel Analysis of Surface Waves (MASW) is increasingly applied in earthquake engineering and geotechnical problems, because of simple field procedures, time and cost saving. It can allow for maximum areal coverage, thus reduces the number of needed boreholes. This study illustrates the importance of the use of active and passive MASW to measure the average shear wave velocities of the upper surface layers (upper 30m) of the city of Irbid in North Jordan by integrating the outputs of the active and passive approaches, and by investigating the relationship between the estimated average shear wave velocity with the following geotechnical variables, Bearing capacity, depth of embedment, and soil thickness. The results show the existence of significant relationships between the estimated average shear wave velocities (Vs30) and a number of geoengineering parameters; bearing capacity (increasing R2 =0.8544), depth of embedment (decreasing R2 =0.8282), soil thickness (decreasing R2 =0.8317).
