Two districts of Lima city, La Molina and San Juan de Lurigancho were investigated and diagnosis of the seismic risk was performed in terms of retrofitting cost. Geospatial data base has been generated of the stock of buildings was produced in order to evaluate the vulnerability of the structural systems in the zone. Geotechnical microzonification was performed to produce the soil characterization of the area and the maximum accelerations thatt can be affected the districts. i t An introduction of the socio economical parameter is introduce in the determination of the seismic risk producing different functions for the diagnosis. 36
