DEFORMATION DETECTION OF POTENTIAL LANDSLIDE WITH INSAR OBSERVATION

摘要

Influenced by geological and climate conditions, Guide County has beenrnidentified as a landslide prone area. Multi-temporal InSAR technique canrnimplement continuous earth surface deformation detection with long timernscale and wide geography coverage. In this research, we employ the SBASrnmethod to survey potential landslide in Guide County. Two anomalousrndeformation regions have been detected by L-band PALSAR stacks.rnPreliminary correlation between the time series deformation andrntriggering factors is analyzed to explore the driving mechanism forrnlandslide movement. As a consequence, L-band SAR has a goodrnapplication potential in landslide monitoring and the results can be thernbasis for landslide recognizing and early warning.
