|Digital World Tectonic Activity Map (DTAM)|
This visualization tool aids researchers and educators in understanding the tectonic activity of our planet for the past 1 million years. DTAM is a Geographical Information System (GIS) that displays a realistic synoptic view of present global tectonism by filling in the cartographic gap between conventional geological maps and plate reconstruction maps. This integrative technique provides a new and unique visualization tool that presents an actual representational view of global tectonics rather than the traditional schematic illustrations (i.e. plate maps) of the past. The map is a Robinson projection showing: actively spreading ridges and transform faults, total spreading rate, major active faults and fault zones, normal faults and rifts, reverse faults (overthrust, subduction zones), and volcanic centers.
