Abstract

Very Long Baseline Interferometry (VLBI) data between the Shanghai station, China and other stations in the world suggest that Shanghai is moving east-southeastward by ~1 cm/year with respect to the stable interior of the Eurasian plate. This agrees with a kinematic model of crustal blocks in Central and Eastern Asia inferred from geologic and neotectonic observations and the results of geophysical numerical studies of the continental collision. The present result gives the first space geodetic evidence supporting the hypothesis that the northward movement of the Indian subcontinent after its collision with Eurasia is partly accomodated by eastward displacements of crustal blocks in Central and Eastern Asia.
