摘要:Korea Peninsula is exposed to landslide problems because large regions of Korea are composed of mountain. As a result, we have a great loss of life and property every year. Conventional survey has many restrictions in terms of time and man power. In recent days, remote sensing has been utilized as an effective technique to detect damaged place as it has many advantages over conventional methods. Synthetic Aperture Radar (SAR) provides the all-weather capability and complements information available. Through differential interferometry technique, we can measure even very small displacement effect. In this study, we generated 12 interferograms of Kangwondo area from JERS-1 satellite images between 1992 and 1998, and monitored landslide area. As a result, around Audae mountain (N 37°. 50', E 128°. 37') and Gebang mountain (N 37°. 44', E 128°. 29') in the north part of Kangwondo and around Uljin(N 37°. 00', E 129°. 08') and Gagok(N 37°.08', E 129°.12') city which is located in the south part of Kangwondo are detected as damaged area by landslide. Also, comparing with weather forecast data, landslide in korea is much affected with a heavy rain during the rainy spell in summer
