Investigation of seismic vibrations and relative displacements of linear collider VLEPP elements

The results of seismic motion measurements in the Protvino region where VLEPP and UNK will be built are presented. Measurements of correlations and power spectra were carried out in the UNK tunnel and on the Earth's surface. Factors that are the main contributors to seismic motion have been investigated. Significant influence of atmospheric pressure on low-frequency seismic motion was observed. The work is important for linear supercollider design.<
