摘      要：The single-station microtremor method is one of the fastest,most reliable,and cheapest methods used to identify dynamic soil *** study utilizes 49 single-station microtremor measurements to identify the dynamic soil properties of the Hilalkent quarter of the Yakutiye district in *** dominant frequency and the amplification factor were calculated by using the Nakamura horizontal/vertical spectral ratio(H/V)*** the soil dominant frequency values varied between 0.4 Hz and 10 Hz,the soil amplification factor changed between 1 and *** H/V values were acquired with lower frequency *** vulnerability index(K_(g))and shear strain parameters that are utilized to estimate the damage that may be caused by an earthquake were *** in the west side of the study area,higher K_(g) values were *** shear strain map was created with 0.25 g,0.50 g and 0.75 g bedrock accelerations,and soil types that lost elasticity during an earthquake were *** average shear wave velocity for the first 30 m(V_(s30))was ***,it was observed that the western part of the study area,which resulted in a higher period and higher H/V,higher K_(g) and lower V_(s30) values,presents a higher risk of damage during an earthquake.
