The local disaster agency along with the military, police and volunteers were evacuating the area.
Indonesia is often hit by landslides. Twelve people including three children died in a landslide on the holiday island of Bali last February.
In September, almost thirty people died in devastating floods and landslides in Garut, West Java.
