In this paper, the authors concentrate on analyzing and assessing the effectiveness of satellite altimetry-derived data in studying geological researches of the East Vietnam Sea. A series of geological features such as faulting system, seafloor spreading ridges, volcanoes, and sedimentary basins have been determined by 2D, 3D modeling based on the interpretation of satellite altimetry-derived data. The achieved results were cross-checked and confirmed by the available shipboard data.
