CONCLUSIONS• Some of the outputs reached in the second year of Japan

Peru SATREPS project were presentedPeru SATREPS project were presented.• Two districts of Lima city, La Molina and San Juan de

Lurigancho were investigated and diagnosis of the seismicLurigancho were investigated and diagnosis of the seismicrisk was performed in terms of retrofitting cost.

• Geospatial data base has been generated of the stock ofGeospatial 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

l ti th t b ff t d th di t i taccelerations that can be affected the districts.• An introduction of the socio economical parameter is

introduce in the determination of the seismic risk producingintroduce in the determination of the seismic risk producingdifferent functions for the diagnosis. 36
