Field observations were made of microtremors at 16 sites widely distributed in Miyakonojyo city, to investigate the dynamic properties of sedimentary basin. The microtremor measurements were carried out using a servo type pick in the present study. Analysis of the Fourier spectrum was also made to investigate the spectral ratios between horizontal and vertical components and the predominant period of the ground. The relationship between the ground conditions and dynamic properties of sedimentary basin in Miyakonojyo basin was investigated quantitatively, based on the results of the microtremor observation. The predominant periods of the ground depend on the strength characteristics of surface soil layers. Finally, use of the microtremor makes such determinations relatively quick and inexpensive and is recommended to gain a better understanding of earthquake damage and evaluation of the ground. The potential use of microtremor can be refined with further research.}, pages = {175--180}, title = {都城盆地の常時微動特性に及ぼす堆積盆地構造の影響}, volume = {40}, year = {2011}, yomi = {ナカムラ, マサキ and ハラダ, タカノリ and カメイ, タケシ and カメガワ, ユウタ} }
