Project Name EQVis: Visualization of Large-Scale Seismic Field Data
Team Members Tung-Ju Hsieh, Falko Kuester and Tara C. Hutchinson
Project Sponsor National Science Foundation (NSF) and Holmes Fellowship Foundation



This project is focused on developing tools for interactive 3-D visualization and exploration to facilitate the intuitive analysis and interpretation of large-scale seismic field data sets. Digital Elevation Maps (DEMs) are used in combination with 3-D rendering, shading and data augmentation techniques to form easily interpretable and quantitative landscapes. A variety of imagery is texture mapped on top of the DEMs to better define the interconnectivity between diverse scientific information. Different geometric proxies are used to represent field data and earthquake events and color-coded to reflect earthquake year, magnitude, and other important parameters. The interactive environment facilitates the exploration of large-scale data sets in geologic and seismic application. Interactive rendering speeds are achieved on a 2.4 GHz Pentium 4 PC, running Windows XP, with 1GB RDRAM and GeForce4 graphics. An example application showing the interactive processing of field collected Global Positioning System (GPS) data sets to aid in the analysis of fault movements is shown below. When properly geo-referenced and treated, the data sets can be presented in a natural and intuitive form that facilitates the understanding of governing events and mechanisms.
