| description | Sengir area is located in Prambanan District, Yogyakarta Special Province,
Indonesia. This area is considered to be a susceptible area to landsliding due to the
interactions of unfavorable conditions such as steep morphology, weak
engineering properties of lithology, and landuse changing. Moreover, there are
significant numbers of landslide traces which are found in the area and those
landslides have provoked several considerable disasters to the habitants living in
the region. The main objective of this research is to assess landslide susceptibility
map, understanding the controlling factors and mechanism of landslide.
In this study, landslide susceptibility map was developed based on four
parameters such as slope inclination, lithology, landuse, and distance to faults.
Supported by GIS software, scores given to each class of parameters were done
according to landslide density, a ratio between the area occupied by the landslide
pixels on a class of a certain parameter and the total area of that class, changed
into percentage. Meanwhile, weights for all parameter were determined by using
opinion-based scores adopting a criterion of analytic hierarchy process (AHP).
The landslide susceptibility zonation map shows that the area of the
prediction groups of very low, low, moderate, and high landslide susceptibility are
29 %, 17 %, 36 %, and 18 %. A significant percentage (18 %) of the research area
has high of landslide susceptibility. As a result, landslide susceptibility map was
a very reliable result as it has a close relationship with the real situation in the
field. The results reveal that the high susceptibility zones were located along the
steep slope showing the coincidence with the landslides locations. The most
controlling factors of landslide occurrence are the slope inclination and lithology.
Meanwhile, the second important parameters in controlling the occurrences of
landslide are distance to fault and landuse. |
