Abstract TM data are major remote sensing data now and can completely meet the precision for the identification of the active tectonic zones in Tibet. Tibet has special geographical and environmental background, and possesses a complete set and wide distribution of active tectonic zones. As conditions are extremely bad, people can hardly approach there. Applying the remote sensing technology and the high-precision TM image, we can achieve the purpose of simple imaging, high resolution, wide projection and low cost. Thus, the rapid and accurate identification of all kinds of active tectonic zones can be realized. The method has overcome such shortcomings of the traditional surveying methods as long periodicity, high cost and impossibility of making insite investigation at many places.
