Abstract

One of the most obvious factors that affect the susceptibility of the mass movement is its forming morphological process, especially the slope aspect. There is a quite strong relation between the historical geology, tectonic activity, lithology, and the slope forming. These aspects are some of the factors that differ the responses of mass movement to the tectonic processes. Response of one location's lithology to this tectonic process can be analyzed with the geomorphology principle through the morphotectonical analysis. This research purposes are to identify the morphotectonical condition at the research location and its impact to the susceptibility of the mass movement there. The methods used here are: (i) field activity to measure the direction of the structural geology; and (ii) studio method to collect and analyze the direction of the lineament of ridges and valleys (drainage pattern) using remote sensing method. These methods and the analysis result then verified with the t-test and f-test statistics to see the tectonical effect in the forming of the morphological aspect at the location. The result shows that there is a similarity from the orientation of structures found at the research location with the orientation of valley and ridge lineaments, which means that the forming of valleys and ridges there were affected by the geological structures at the research location. It is also confirmed by the t-test and f-test that shows an association between these data. With the association between the geological structures and the formation of the ridges and valleys at the research site, the level of soil susceptibility at the research site will be high, considering the deformation rate of the slope is also influenced by the availability of structures in the area.
