Abstract

In order to enhance the linear image, the authors conducted directional filtering of the TM image and digital elevation model (DEM), and then used false color composite technique to produce a base map. Through interpretation of the base map and field verification, the distribution of fractures in Qingyuan County was mapped. The spatial correlation between fractures and mountain hazards was also investigated. The results show that if a region is affected intensely by deep faults, the positive correlation between mountain hazards and intersection density of fractures or density of fractures are existent but not notable. By contrast, the porphyritic distribution of mountain hazards caused by volcano-tectonic activity is quite obvious.
