| dc.description.abstract | This research aims at identification of spatial plan zonation in rockfall prone areas. Research method
applies hazard, vulnerability and risk analysis as an input for spatial modeling using Multi Criteria
Evaluation (MCE). Research reveals that in Girimulyo is susceptible towards rockfall. In the last decades,
there were 16 occurrences of rockfall that impacted to physical damages. Fortunately, such disaster did not
cause any harm to human life. Therefore, research argue that physical vulnerability analysis can be analyzed,
while social vulnerability cannot be analyzed further, since it had less data support. According to the research,
there are more than 48 housing units located in hazard zone. Hence, local government should initiate
structural mitigation to avoid further loss. Research also reveals that areas with high susceptibility will not
directly consider as high risk zone, unless it has high vulnerability index. Example: areas along escarpment,
where it has high susceptibility, but it has no element at risk in the area. Thereby, research tries to present
zonation for prone hazard areas, using risk index. The result is quite representative, since possible areas to
be developed is anywhere alongside road network. Indication of the area is produced from the multi criteria
analysis. Multi criteria analysis is an essential method to combine spatial data and its attribute. Using such
method requires more data input and expertise in justifying indicator to be selected. | en_US |
