For seismic microzoning on damage of wooden houses, the vulnerability functions of wooden houses should be defined. In this study, the vulnerability functions for different construction age are proposed using the damage survey data in Higashinada, Kobe area during the 1995 Hyogo-ken Nanbu, Japan earthquake. The proposed vulnerability functions are applied at five strong-motion stations in Kobe where the main shock records are available. The estimated damage rates agree well with the observations, suggesting the validity of the proposed functions. By using the proposed functions together with populations of wooden houses estimated from the Grid-Square Statistics data and peak ground velocities computed for a hypothetical earthquake, a procedure for seismic risk mapping of wooden houses is shown. The procedure is applied to the northern part of Kanagawa-prefecture.
