Microtremor survey was conducted together with boring survey for the determination of site amplification and strong ground motion characteristics in southern Yogyakarta Depression, Indonesia. 1-D dynamic response analysis by equivalent linear method had been performed based on results of microtremors survey, data from nine boreholes, and standard penetration test results. The DYNEQ Program, version 3.25, coded by Dr. Nozomu Yoshida in 2004 was used for 1D dynamic response analysis by combining with Bunsanf HV Matsuo Program. 1-D seismic response analysis had been performed by using the input...
