Abstract

Unit of Area Genetics (SGW) as one of the methods in considering geological aspects for geologicarea-based development. The geological condition as part of the natural movement in a particularcondition makes it possible to predict its effect on the movement of an area in particular with regard tonatural disasters. Pangalengan who has a million beautiful natural charm, especially from the point ofpan-dang geology need it to be studied based on geological data. The charm is the presence of activevolcanoes in the region such as Mount Malabar, Mount Wayang, Mount Windu and others. In addition,the morphology of Pangalengan is relatively well represented in the highlands, hills and mountainareas as part of Java's tectonic activity. Another evidence of such activity is the existence of fault linesin the Pan-galengan mountains of Southeast-Northwest.
