内容記述 | The result of the present study is summarized as follows: The distribution of excess mass in the earth's crust in the region near Izu-Osima was determined by using the data of gravity anomalies on the surface of the earth. In determining the distribution of the excess mass, we assumed, for convenience in calculation, that (i) The earth's crust in the region under consideration is divided into 75 blocks or cubes; and that the excess mass that is responsible for the gravity anomalies on the surface of the earth is concentrated at the centre of each of such cubes. (ii) The density of the excess mass ρ'was assumed to be 0・1 or zero. After the distribution of excess mass was thus determined, the deviations of the verticals for the stations, Okada and Habu, were calculated, and the results compared with actual data, with satisfactory results. It should be added, however, that the mode of distribution of the excess mass is not a unique solution. | |||||
