A GIS database for seismic damage risk assessment was built in and around Marikina city, a suburb bedroom town of Metropolitan Manila. Building shape polygon data were available to measure building characteristics, as a layer of topographic CAD data which was digitized on 1:10000 scaie of aero photos. Buildings were classified into two types of residence overiaying the existing land use map; high dense housing and standard one. Those residentiai zones were found to have different trends of building density and histogram of building area. The seismic resistant quaiities of the buildings were evaiuated based on such regionai characteristics. Vulnerability curves of GESI method to the buiIding groups were decided and total number of casualties in the city was estimated at about 1900 people.
