Leveling surveys of the neighbourhood of Muroto Point, Shikoku were carried out seven times after the Nankaido great earthquake in 1946. The results of the surveys together with those before the earthquake show that the remarkable northward tilting of this locality, about 6.2" in magnitude, accompanying the earthquake is has been gradually recovering, and the present rate of southward tilting nearly constant, being 0.035"/ year, which is almost equal to that for the pre-earthquake period. The main results are graphically represented in Figs. 4 and 5.
