The effectiveness of local network after earthquake has significant impact on the function of hazard mitigation. The main purpose of this paper is to articulate the method of network evaluation in the earthquake hazard and to provide with feasible evaluation method based on the data availability. Two levels of network evaluation are considered in the study, which includes the evaluation of the individual link and the network system. The evaluation of single link applies the factors of width of road, parking, debris, the activities beside the road and some indicators composed of them. For the network system evaluation, a connectivity index is introduced and modified to illustrate in the paper.
