18. Conclusions HVSR 3 periods for each site discarded the biggest cause of high uncertainty. The other 2 were between 0.3 - 0.4 hz and 0.8 - 1.4 hz MASW The only profile was compared with REMI showing a good fit between them REMI 5 layers Max depth around 160m and > 2000 m/s for Vs. Low velocity layer between 45 - 100m of depth Airport soil is Class B SPAC No low frequencies at the p-f plot, which make it difficult to identify this range. Spac results present high misfit. They however are in good agreement with other methods

19. Conclusions HVSR High influence on high frequencies. Uncertainty in the analysis. Provides a fast estimate of the basin shape and depth. MASW Easy to make the site caracterizacion but it takes more time for the acquition of data. REMI Easy to classify a site and do the caracterization. Very fast analysis, and good resolution of penetration. SPAC Time consuming on data acquisition and analysis. Special needs for the site to be able to do the acquisition.
