Landslides have occurred massively, comprehensively and at the same time in Sukajaya Sub District, on January 1, 2020. Sukajaya Sub District is included in a high landslide hazard zone. Many factors cause landslides in Sukajaya Sub District, namely: slope, geological and soil conditions, land use, drainage patterns, rainfall, and human activities. The most influential dominant factors are: extreme daily rainfall before and during landslides, types of volcanic rock that form very thick and loose soil, and steep-very steep slopes. Analysis of various factors causing landslides, landslide zoning and analysis of landslide mechanisms, will greatly assist in handling and anticipating future disasters. Arrangement of the area after a landslide is very necessary to be able to reduce the risk of disasters and build a sustainable safe area. Many things that can be done in the arrangement of the landslide area include: former and landslide-prone areas made conservation areas, relocation of threatened populations to safe places, drainage arrangements, strengthening of cliffs and road slopes, avoiding living on hill slopes and river courses, greening with hard plants and strong roots. The formation of community preparedness is also needed to form a community that is resilient to landslides.
