Abstract: Xuzhou is one of the cities chosen for urban earthquake hazards prediction in China. The main factors causing urban earthquake hazards are the urban geologic background and the present urban situation. In this paper we take spot coverage data and macroscopic earthquake hazards as bases, and take the social factors, such as structure type, building quality, building density, population, open space and road conditions, into accound. With the help of the method of vulnerability analysis for multiple factors we have completed the vulnerability analysis of the urban social factors for Xuzhou. From the results obtained in the present study we indicate the weak points and places in the urban earthquake preparedness work, try to provide a basis for improving earthquake preparedness so as to mitigate natural calamities.The result of the seismic vulnerability analysis is presented as a map of seismic vulnerability analysis. The total index M is the base for compiling a map of vulnerability analysis. Of the total vulnerability index M, the building (structure type, building quality) vulnerability index b makes up 60—70 per cent, it is the trace of matrix C which the building vulnerability tendency matrix A times the building composition matrix B^T.
