For detailed seismic hazard mapping, we created 50m-mesh engineering geomorphologic classification map using the existing 250m-mesh map, high-resolution satellite images and digital elevation model in the west part of Kanagawa, Japan. To validate the estimated geomorphologic mesh map, the average shear wave velocity in the upper 30m (AVS30) estimated from the 50m-mesh map is compared to AVS30 calculated from observed data such as PS-logging data and boring data. The standard deviation of ratio between observed AVS30 and estimated AVS30 is logarithm 0.15. The variance of the filled land and the boundary area of terrace, lowland are lager than that in the other areas. The histogram shows that the estimated AVS30 almost agrees with the observed AVS30.
