Abstract：Collapse is a typical geologic disaster in karst area. The collapses are increasing with the intensity of the man's economic activities. Soluble rocks cover a area about one third of China, therefore predicting and managing of the karst collapse are taken to be a serious matter. Remote sensing techniques area significant method of detecting collapse. Within these techniques, visible aerial photography is the most common, and various criteria of interpretation have been set up. Thermal infrared scanning technique could also be a considerable method in the special investigation, but the surface temperature of the target needs to be measured in the field for several days and The flight altitude is selected appropriately. Satellite imagery interpretation is a assistant method associated with ground investigation on predicting collapse and studing the region distribution of collapse.
