AbstractThe potential seismic amplification and attenuation properties of an area are well correlated with the shear wave velocity (SWV) profile of crustal rock. When local strong motion records are lacking, the a ttenuation behaviour of future earthquakes can be inferred fro m a crustal SWV model that is representative of the area of interest. Details of the SWV profile close to the e arth surface (1-2 km depth) are particularly critic al. Unfortunately, such details cannot be obtained by c onventional seismic reflection/refraction surveys. This study demonstrates the use of information from a combination of sources to produce a set of composite SWV profiles for four principal geological formations that are p revalent in Hong Kong. Their respective local upper crustal modification factors have been computed and the significant differences have been highlighted.
