The remote sensing monitoring of geological hazards on the Moxi Platform in Luding County

Sichuan Province

China

was carried out using remote sensing data from the multi-temporal and multiplatform satellite.Evolution trends and stability of geological hazards were obtained

and a scientific basis for prevention of geological hazards was provided.Results from the remote sensing monitoring reveal that during the period of nearly four years from January 2

2006to December 21

2009

new debris flows and avalanches did not occur at the platform

which means that there were no recurrence of debris flows and avalanches

debris flow were intermittent

and avalanches and most of landslides were in a steady state.There was only one new landslide still in developing and precarious state

which is subject to further development and needs to be monitored.Slides and collapses induced by river erosion and shallow debris flow on margins of the Moxi Platform are always developed continuously

which will threaten the stability of bank and reduce the area of the platform and hence needs handling at early date.
