Geodesy in Japan

Abstract

Abstract. T. Inoh was the first who completed a nation-wide map of Japan, in the beginning of the 19th century. He determined geodetic positions by distance and angle measurements and by astronomical observations.

Applications of Geodesy to Geodynamics an International Symposium

“…No values were given for the associated elevation changes, but they were described as being too small to affect the observed gravity values. In another area of Japan, the Muira Peninsula, which was uplifted 1-2 m during the 1923 Kanto earthquake, repeated gravity and leveling surveys conducted since 1955 have shown the expected inverse correlation between gravity change and elevation change (Hagiwara, 1974). However, the gravity changes are about ten times larger than expected.…”
