ABSTRACT
Very few studies have been conducted on the larger oceanic part of the Indian plate using space geodesy. In order to holistically determine the kinematics of the Indian Ocean Basin between Antarctica and India, the data available are very sparse, and characterization and the delineation of the plate boundaries, especially in the Indian Ocean, are poor. The study focuses on GPS geodesy to improve the understanding of the complex plate motions, diffuse and poorly located plate boundaries, and striking intraplate deformation that characterize the Indian Ocean Basin and also addresses several of these issues, as follows:

• How rigid is the Indian plate and Indian Ocean Basin? • Does relatively high level of intraplate seismicity on the oceanic
part of the Indian plate indicate internal deformation in excess of other plates?
