The paper presents the results of the ground motion measurements and dynamic analysis performed in The Polish synchrotron radiation facility Solaris. The analysis has been carried out within the framework of the installation experimentals lines inside SOLARIS bilding and accelerator tunnel. The equipment used in this study consists of 4 seismic, high sensitivity, ceramic flexural ICP accelerometer. Models 393B31. (PCB) , which performed measurements in one vertical directions. The first analysis was to evaluate the power spectral density for each sensors and event. The power spectral density is calculated from the auto power spectrum. The power spectral density shows a typical curve with the micro seismic peak between 0.2 and 0.4 [Hz]. It is important to point that ground vibrations should not be ignored in planning accelerator facility. All over the measurement, the RMS integrated level in th e vertical direction at 1 [Hz] were calculated and presented in paper.
