| Summary: | Mass movement mapping in Plosorejo and Gempolan village, sub-distric of Kerjo,
Karanganyar, Central Java because these area is known frequent of mass
movement. The mapping method used direct mapping method, which is mapping
the mass movement by observation in the field, with determination criteria of
mass movement susceptibility based on realcondition in the field. From the
results of direct observation in the field, it is known that the occurance of mass
movement in the study area has several dominant control factors such as the
degree of slope, the influence of geological condition, soil thickness, also bad
condition of land use development and the trigger factor is rainfall intensity was
high. The results of mass movement susceptibility mapping in the study area is
Mass Movement Susceptibility Map in which there are 4 zone of mass movement
susceptibility, those are low of mass movement susceptibility, medium of mass
movement susceptibility, high of mass movement susceptibility, and very high of
mass movement susceptibility. From the research, it is known that the high and
very high zones of mass movement susceptibility had most of the mass movement�s
occurances, so the development area recommendation only for temporary area
such as rice fields, forests, and gardens. To low and medium zones of mass
movement susceptibility can be recommended for permanent area such as
residential areas, placesof worship, and schools.
