AbstractPrecise gravity measurements have been carried out by using LaCoste & Romberg gravimeters, repeatedly, in the southeastern part of Shikoku District, in order to detect the secular change of gravity.The results obtained by the gravity measurements were compared with the results of levelling surveys which were performed during the almost corresponding period. It shows that the gravity changes obtained were not the correlation with the vertical movements obtained from levelling surveys.
