| 抄録 | Rain-induced landslides may result in disaster by destroying homes and buildings. Fluid landslides are characterized by rapid movement and long run-out distance. Aerial photos have been used to observe and measure the slopes. In addition, a new technology called airborne laser scanning, is a promising tool for observing and measuring slopes. In this study, hilly terrain where landslides have occurred was measured by airborne laser scanning. Furthermore micro landslide characteristics such as scars were identified in detail, by combining contour maps based on airborne laser scanning data and remote sensing such as aerial photos interpretation. |
