The Relationship between Linear Weak-Information of Radar Image and Subordinate Faults in Landslide Area of Hong Kong
摘要
Abstract
By processing the Airborne L-SAR image of the study area,we selected the weak -information of SAR image as indicator of subordinate faults,and traced the st ructural background of landslides in the region.The regional fault in the study area is the NE strike-slip fault.Its sinistral movement forming a serial subo rdin ate faults,including R plan,P plan and R′ plan,which are represented as weak i nformation of lineation in radar image and related to the development of micro- g eography.By selecting and enhancing the weak information,we made the deformati on frame of subordinate shear faults.Together with field investigation,we foun d that the location of P shear plan on the northeastern Jubilee Reservoir can fo rm landslides of gravity unbalanced alluvium,with a background of strong strain deformation belt.The newly formed landslide of boulder falls was located at so utheast of Jubilee Reservoir.It has features of structural tension background,and relates to the subordinate faults with pull-apart action on the direction o f the R shear plan.关键词
