Peru SATREPS project were presented.
presented• Two districts of Lima city, La Molina and San Juan deLurigancho were investigated and diagnosis of the seismic
risk was performed in terms of retrofitting cost.
• Geospatial data base has been generated of the stock ofbuildings was produced in order to evaluate the vulnerabilityof the structural systems in the zone.
• Geotechnical microzonification was performed to produce thesoil characterization of the area and the maximum
accelerations

ff t d theth districts.
di t i t• An introduction of the socio economical parameter isintroduce in the determination of the seismic risk producing
36
different functions for the diagnosis.
