Damage estimation for scenario earthquakes is conducted by local governments for emergency response planning. However, local governments usually do not possess detailed data of utility pipelines and hence, they generally estimate the distribution of pipeline length. A problem of this approach is that the accuracy of pipeline length estimation is not so high. This study tries to perform the estimation of water-pipeline data for more accurate earthquake damage assessments. The method to estimate the pipeline length is proposed from road network data by using GIS for densely inhabited districts (DIDs). But outside of DIDs, buildings data must be introduced in addition to road network data as parameters to estimate water-pipeline lengths in grid cells.
