#microtremor

Considering the possible local site effect is one of the most important facts in seismic hazard assessment. Depending on the local site condition, the characteristics of the seismic waves propagated through different geological layers and amplified the surface ground motion. In this study, one of the geophysical method of microtremor observations were carried out at 112 sites throughout the Taikkyi area. After analyzing the recorded microtremor observed data by Cygwin Software, we determined the horizontal to vertical spectral ratio HVRs that reflects the local site effects of the study area. The main outcomes of this research is to develop the fundamental frequency map and peak amplitude or soil amplification map of Taikkyi area. According to the evaluation results, the fundamental frequency is ranging from 1 to 2.3 Hz and most parts of Taikkyi area show in the range of 1.3 to 1.6 Hz. The peak amplitude of HVRs potential soil amplification is ranging from 1.5 to 3.6 and most parts of the area are in the range of 1.5 to 2.5.
