The European Organization for Nuclear Research is an organization that operates the largest particle physics laboratory in the world. CERN's main function is to provide the particle accelerators and other infrastructure needed for high-energy physics research – as a result, numerous experiments have been constructed at CERN through international collaborations. Many activities at CERN currently involve operating the Large Hadron Collider (LHC) and the experiments for it which most of them are situated in the 27 km circumference circular tunnel around 100m under the ground. One of the main reasons for this location is requirement of stability for the beam. This means that vibration conditions must be taken into account. Additionally, the High Luminosity upgrade of the LHC (HL-LHC) will require unprecedented orbit stability and the effect of seismic noise might become a relevant source of luminosity loss. Many studies have been conducted in the past to characterise the actual ground motion in the LHC tunnel, and recently a few geophones have been installed to permanently monitor the ground stability in two LHC locations. The CERN seismic network, equipped with both broadband and strong-motion seismometers, allows now for continuous monitoring of vibratory conditions. Moreover, in the past, due to transfer function approach the impact of heavy machinery work on the induced oscillation of the magnetic centre was calculated. Currently, additional two surface monitoring stations were placed at the sites where new shafts are being excavated. This allow for constant monitoring of civil engineering works and impact of specific machinery on vibration levels in the tunnel and connect specific events to the machinery working on the site. Full characterisation of the equipment impact will allow to foreseen future vibration problems for LHC and its upgrades depending on the activity on the surface.
