The dynamic soil characteristics in Eastern Ghoota, which is located on
Damascus basin, was studied to estimate the predominant period and the
amplification factor in all sites, using Nakamura's technique. This technique is
considered as one of th
e important empirical techniques used in the world to
study the surface geology effects on site response. About 1000 seismic noise
measurements were carried out in 265 sites covering different geology deposits.
The H/V spectra ratio were calculated and analyzed to determine the site
predominant period and amplification factor. The results exhibit good
correlation with the local geology and the modeling of geotechnical boreholes,
whereas the predominant period and amplification factor values vary clearly
from site to site.
