Landslide in Korea occurs generally in summer, and rainfall is a major factor to trigger landslides. This study evaluates the
applicability of radar rainfall to estimate landslide occurs locally in mountainous area. Temporal changes in spatial
distribution of rainfall is analyzed using radar data, and the characteristics of rainfall in landslide area during the landslide
occurred in Inje, July 2006. This study shows radar rainfall field can estimate local landslides more precisely than the
rainfall data from ground gauges.
