This report introduces the HL-LHC project and discusses the importance of monitoring the effects of earthquakes on the present LHC beam orbit and luminosity using a novel instrument, the Precision Laser Inclinometer (PLI). After a brief description of the instrument principles, a comparison of data from the PLI and from the LHC beam instrumentation in the event of earthquakes is given. The aim is to characterize the response of the accelerator to remote or nearby Earth surface movements. The first results from simulation in comparison with data are presented. The impact of vibrations on high luminosity small-sized beam colliders, as in High Luminosity LHC among many other future projects, the possible applications of the PLI instrument and ideas about possible feedback systems conclude the contribution.
