TETHYS is an interdisciplinary GIS database project funded by the NSF. The database is built to act as a tool for researchers, educators, and students studying continental collisions, and as a means to better characterize natural hazards in one of the world's most densely populated regions. Our ArcIMS servers and tools provide geophysical, geochemical, geological and remote sensing data on the web in GIS format.

This project builds on the International Geological Correlation Project (IGCP) 430, a UNESCO-IUGS program addressing links between plate collision responses and Tethyan geologic hazards.
