Abstract
GPS observations for the determination of precise geoidal height in a volcanic area were carried out at the geodesic control points in and around Sakurajima volcano. The spatial pattern of the geoidal undulation was detected to coincide with volcanic depression in and around the crater and agree with the profile of volcanic underground structure determined from gravity anomaly by Yokoyama and Ohkawa (1986). Two positive geoid undulations in the E-W direction were detected on the outer sides of the depression.0utside the caldera’s outer wall, other positive geoid anomalies in the E-W direction were found. These are considered to be produced by the formations of Kagoshima graben and Sakurajima volcano in the tectonic field of the E-W compression and N-S elongation. For the prognosis of the volcanic eruption, time-varying geoidal height in the case of the 1914 great eruption was estimated.
