A procedure for predicting the isoseismal map of a hypothetical earthquake is proposed using the Digital National Land Information as the GIS application to seismic microzoning. The average shear wave velocities of ground from surface to 30m depth, AVS, are estimated from site parameters included in the Digital National Land Information. The isoseismal map is predicted by multiplying of the site amplification factor estimated from AVS, and the intensity of standard ground motion which is obtained from the attenuation law. The calculation was conducted for the 1987 Chiba-ken-toho-pki earthquake. The calculated values showed good agreements with the observed ones.
