Abstract

The results obtained with different seismic methods, both active and passive, and conventional geotechnical tests, are complementary and consistent based on the characteristics of the soil column, and the S-wave velocity values. Passive seismic methods, in conjunction with up-to-date active seismic methods, and traditional geotechnical techniques (field and laboratory tests) have been applied on municipalities that constitute the Granada Metropolitan Area (972 km2) in Spain. This important area is 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 seismic induced phenomena. This work means an important contribution to accomplish an appropriate microzonation study for this area, considered as the zone under the most seismic risk of Iberian Peninsula. That will be useful for prevention and intervention actions, not only for the present buildings, but also, for future construction planning.
