... the fractures and the free-surface under incident S-wave is investigated by using a two-dimensional UDEC model with fractured zone characterized as one, two, three and four sets of parallel fractures with varied intersecting angles. The results show that wave amplification factor varies according...

... . The comparison between the main frequencies of the events and the fundamental frequencies of the site show resonance effects. The raised amplifications were demonstrated to be caused by geological site effects, related to the upper geotechnical unit and not by the topography. These results show the importance...
