Crustal Deformation Observed at the Sagami Bay. Area, Japan, by means of GPS Interferometry

The Japanese University Consortium for GPS Research

Abstract

Several years of repetition of GPS observation at the Sagami Bay area, south Kanto, Japan, suggest that the crustal deformation is proceeding in the area with roughly north-south extention and east-west contraction. West to south-westward migration of southern tip of the Izu Peninsula, northward migration of the Izu-Oshima island, and north-westward migration of southern tip of the Boso Peninsula are also found . These deformations seem to be harmonious with other geodetic data and tectonic models .
