Abstract: The following problems are presented in this paper. The remote sensing geological methods are used to process and interpret remote sensing information for the middle of Tancheng-Lujiang fault zone, the distribution of main faults in the region, especially the faults in cryptic fields and some transcurrent faults which are approximately perpendicular to the main faults.The results which are essentially in conformity with the field works, are achieved by processing the satellite tapes using the method of enhanced high-pass fittering. Some useful data are derived from also essential phenomena analysis of active faults and measurement of apparatuses.We have established the preliminary interpreting marks of active faults in the region after interpreting the layer and tectonics and examining them in field works.The surface distribution of the faults in the region, including the situation of the transcurtent faults and the characteristics of the active faults, are clearly shown in Fig.2, which illustrates also the characteristics of the active faults from north to south.
