| Abstract: | SummaryMonitoring of Recent Geological Events in the Khumbu Area (Himalaya, Nepal) by Digital Processing of Landsat MSS Data In September 1977 a serious flash flood catastrophe happened in the Khumbu area (E Nepal). By means of digital processing of Landsat data scanned before and after the flood it was possible to demonstrate that it originated in the uppermost Nare Drangka Valley. It was caused by the break of a frontal moraine which induced the outflow of a glacial lake. Extensive erosions and slides can be spotted in the satellite image.With 13 Figures |
