000020229 520__ $$2eng$$aHistorical and recent Chilean earthquakes (1906, 1960, 1985, 2010) showed similar building damage distribution in Viña del Mar city related to ground conditions and building height A detailed analysis of 122 geotechnical reports has allowed us to obtain their geotechnical parameters and the VS surface ground structure (calculated from NSPT data) up to a depth of 30 m in 62 of these sites. The site predominant period (Tp) was estimated from ambient noise records (with the HVSR technique) in 84 points regularly spaced (∆ ~200 m). The highest values (Tp > 0.8 s) were found nearby the Marga-Marga fault trace, and gradually decrease on both sides up to 0.4 s close hill zones, being less than 0.2 s at the hills. Two estimates of the basement depth (VS> 800 m/s) from the VS(z) and H/V observed curves show similar results: depth > 60-70 m in onethird of the plain area, reaching 120 m in the center of the basin. The spectral amplification obtained in 12 representative sites by computing the 1-D response of the shallow Vs structure exceeds a factor of 4 in the area with greater thickness and is greater than 3 in the remaining area for the corresponding key periods.
