Abstarct: The purpose of this study is to determine the shear wave velocity in the surface laxyers of the earth using recorded Microtremor data. Microtremors are constant movements of the earth's surface with very low amplitude that occur from natural sources such as ocean waves, or from human factors such as machine traffic. After recording the microtremors by seismometers, the Rayleigh wave phase velocity diagram will be obtained from the analysis of the recorded waves, and in the next step, the shear wave velocity profile of the underground structures will be obtained by inversion techniques. In this research, miniature arrays have been used which determine the shear wave velocity structure of surface laxyers in Shahroud. For this purpose, an array with a diameter of 60 cm was placed on the ground. In this array, a seismometer was placed in the center and three other seismometers were placed on the perimeter of the array at the same segment intervals. After recording the data and analyzing the microtremor results, the subsurface structure was estimated and the results were compared with borehole observations from geotechnical surveys. During these studies, it was found that the results of microtremor study in determining the number and type of soil laxyers which are consistent with the drilled geotechnical borehole and the resulting shear of wave velocity is obtained as the shear wave velocity baxsed on the relations of Journal 360 of the Management and Planning Organization. Therefore, it seems that if there are suitable fields for microtremor waves, the use of miniature arrays can be used as an effective way to identify the earth's surface laxyers.
