Application of drainage analysis to infer 'hidden'' regional or localn tectonic deformation

摘要

Some features in the landscape are the direct result of earthquake and tectonic deformation. The recognition and analysis of these geomorphological features allows the identification of regions subjected to past earthquake activity or tectonic deformation, which can be directly applied in many areas of engineering geology. However, some regions lack evident geomorphological features despite being subjected to recurrent earthquakes and/or ongoing tectonism. Drainage networks are very sensitive to
