Summary The research project of the Spanish Ministry of Science and Innovation that is going to be carried out is presented. The subsidy for this project has been obtained in a competitive call at the national level. One of the main aims of this project is to study the optimal and affordable use of seismic methods, active and passive, to characterize the subsoil from a geotechnical point of view with a suitable detail that would let us properly predict induced seismic phenomena, such as liquefaction, unexpected soil settling, and failures. It is planned to conduct improved passive seismic methods, in conjunction with up-to-date active seismic methods and traditional geotechnical techniques in the 32 municipalities that constitute the Granada Metropolitan Area (972 km2) in Spain. This important area is located in the most dangerous region of Spain in terms of seismicity and seismic risk. Moreover, this region presents clear evidence of significant seismic amplification and susceptibility to induced phenomena. In this way, obtaining a microzonation of this area will enable to precisely quantify and pinpoint these effects and to establish empirical relationships between important parameters such as the corrected SPT-N, the liquefaction potential index, the Poisson's coefficient, densification phenomena.
