description This document presents an analysis of ground motion induced orbit drifts and presents two models describing the propagation and amplification of ground motion on the SPS, LEP, and LHC orbits qualitatively and quantitatively. The analysis shows that the largest ground motion contribution to the orbit drift on the time scale ranging from seconds to a month is due to random ground motion and is barely influenced by correlated ground motion. An upper limit of the expected drifts at the LHC, SPS, and the TI8 and CNGS transfer lines due to ground motion only are given. The predictions are supported by beam measurements at LEP in 1999 and ground and beam motion based measurements performed in 2004 in the SPS and TI8.
