The article presents the results of experimental studies aimed at evaluating the effect of non-tidal variations in the free-fall acceleration. The change in the free-fall acceleration due to changes in the moisture saturation of rocks, changes in atmospheric pressure and ambient temperature was studied. It was found that the greatest influence on the FFA is exerted by changes in atmospheric pressure and ambient temperature (30–35 mcGal).

Keywords: free-fall acceleration, variations in free-fall acceleration.
