Abstract

Landslide is the third largest disaster occurred in Indonesia, including in Probolinggo District. Analyze the place exposure patterns toward landslide disaster due to heavy rainfall which triggering the landslide in Probolinggo District is the purpose of this study. Daily rainfall data in 1990-2015 are used to obtain the frequency of heavy rainfall regions (> 50 mm/day, >100mm/three days and >150mm/five days) using the interpolation method based on Thiessen Polygon. The potential landslide region are obtained by using SINMAP models which is verified by the landslide location data from 2015 to 2016. Descriptive spatial analysis using the overlay technique showed that 50,30% (85.358 Ha) area in Probolinggo District has the potential of landslide, especially in Sub District Krucil, Andisol Soil region, the slopes of 15-40% region, and the rainfall of 1500-2000mm/year region. The place exposure patterns toward landslide disaster due to heavy rainfall in Probolinggo District is in the region which has the higher potential of landslides and heavy rainfall frequency, the level of place exposure to landslides disaster due to heavy rainfall will be higher.
