Landslide hazard in Indonesia has caused many victims of people killed and number of casualties. This was created by such geologic condition, climate and human factors. Especially for the areas, in which economic and transportation is vital, monitoring of landslide by using GPS has been done episodically. The result of monitoring for Bandung – Jakarta and Bandung – Jogyakarta main roads within 2 months period in rainy season, showed 5 cm road sliding was detected. Two dimensional resistivity imaging survey was done in understanding the degree of sliding slope and thickness of the upper layer. Usually for the upper layer of 3-5 m in thickness with slope of 20 degrees, causing the damage of building, roads and many other public facilities. The areas of those fulfill the above criteria was stated to be unlikely for human living, limited farmer activities and needs road maintenance with a special engineering technique. |
