In this paper we focus on advantages of the parallel visualization and remote visualization, and propose a new scheme: remote data extraction and parallel visualization analysis diagnosis. For the multi-scale feature of geological research objects, we establish a multi-scale extraction algorithm and corresponding parallel algorithm of large scale geological data with the aid of multi-scale and multi-resolution data extraction tools. Finally, we realize the multi-scale display of tsunami data based on VTK software.
