Abstract
A passive seismic investigation technique known as the spatial auto-correlation (SPAC) method has been used to measure shear wave velocity profiles down to depths of approximately 100m around the Melbourne metropolitan area. A series of surveys have been carried out in different suburbs in Melbourne to develop an average shear wave velocity profile for the bedrock formation. This paper presents details of the surveys including geometries of the geophone arrays, measured auto-correlation spectra, theoretical spectra derived from layered earth models, and the resulting shear wave velocity profiles. These shear wave velocity profiles can be used to assist in modelling the seismic attenuation relationship and radiation damping properties of the bedrock in the area as demonstrated by companion papers presented at this conference.
