Enterprises are exposed to various risks. 0ne effective measure for risk aversion is a defense in depth, which can be achieved by providing the alternative building. However, the seismic risk is caused by the common cause so that the effectiveness of a defense in depth may not be observed. In this paper, a method to obtain the conditional seismic hazard curve correlated to the seismic hazard curve of the main building was proposed. Using this method, 20 buildings were examined for their adequacy as an alternative building. Also Examined were 291 site, followed by the following findings ; (1) distribution of variability in attenuation relation has a large effect on results, (2) correlation in the ground motion intensity may differ corresponding to the given annual probability of exceedence, and (3) arrangement of alternative buildings can be determined by the conditional seismic hazard curve.
