It was caused by the absence of disaster response organization, socialization, basic training about landslide, the making of disaster early sign system, and disaster prone map. Moreover, the quality of the landslide barrier infrastructures such as gabion, embankment, concrete wall, and foundation was still low. The maintenance was also still low, because it was only done when there was a damage. In addition, there were no evacuation facilities or routes in place to anticipate landslides.
