抄録: The heavy rainfall which occurred in July, 1982 brought about natural disaster and subsequent serious damage over the western and the central Kyushu in Japan; particularly debris flows and slope failures on 23rd to 24th July in Nagasaki, and farm submergence on 23rd to 25th July in Kumamoto. This paper investigates these natural disaster in both areas of Nagasaki and Kumamoto through the remote sensing technique. Remote sensing data used for investigation were obtained with the Multispectral Scanner (MSS) and the Return Beam Vidicon (RBV) cameras on board Landsat-3. These data are analyzed analogly for the disaster in Nagasaki and digitally for that in Kumamoto, respectively. It follows that manual interpretation of MSS and RBV imageries obtained before and after the disaster is capable of detecting a debris flow and a slope failure, and that binary classification of MSS data obtained after the disaster, using a computer-compatible tape (CCT) , succeeds in mapping of flooded zone and calculation of its area.
