[SGD21-P01] Gravity variations and vertical displacements over the Japanese islands

3-min talk in an oral session

*Koji MATSUO¹, Hiroshi MUNEKANE¹, Yuki HATANAKA¹ (1.GSI of Japan)

Keywords:time-variable gravity, vertical displacement, GRACE, GNSS, cryology, hydology

We are going to analyze satellite gravity data for the Japanese islands and discuss the characteristics of gravity variations in each region. To corroborate our results of gravity analysis, we shall show the comparison results with vertical crustal deformation from GNSS observation.
