The comparison of the change in the height of Bench Mark at Aburatubo resulted by Levelling Survey and that of Mean Sea-level, was already made, and reported in my recent paper [1]. In that case, pretty good parallelism was observed in the changing mode, but we must be obliged to perceive some discrepancy in the numerical value, that of mean sea-level being somewhat greater than that obtained by Levelling Survey. <BR> In this case, the result is contrary, the value of the change of mean sea-level being smaller than that obtained by Levelling Survey in the same epoch. Thus, some question was thrown that the Standard Origin of Bench Mark at Miyakesaka meight has subsided in some amount, about 20 mm during the period of two years. It's value is not sounnatural, remembering that, it was 86 mm on the occasion of Great Earthquake of September 1, 1923.
