滑坡是发生在印尼爪哇等热带湿润气候山区的重要自然灾害。作为经济和政府活动的中心，爪哇岛成为印度尼西亚人口最多的岛屿，并且每年都在增加。这种情况使人口更容易受到危害。爪哇人口为1.2亿，占印度尼西亚人口的60%，仅占印度尼西亚总面积的6.9%。由于其地质环境、地形特征和气候特征，爪哇是最容易发生滑坡灾害的地区，并与以下几个因素密切相关：（1）位于俯冲带，爪哇60%是山区，火山构造山脉，印度尼西亚129座活火山中有36座活火山，这些火山物质被强烈风化。（2）爪哇属于潮湿的热带气候，10月至次年4月的雨季降雨量很大。除了这些“自然”条件之外，由于人口密度高，人类活动是滑坡发生的另一个因素
Landslides are important natural hazards occurring on mountainous area situated in the wet tropical climate like in Java, Indonesia. As a central of economic and government activity, Java become the most populated island in Indonesia and is increasing every year. This condition create population more vulnerable to hazard. Java is populated by 120 million inhabitants or equivalent with 60% of Indonesian population in only 6,9% of the total surface of Indonesia. Due to its geological setting, its topographical characteristics, and its climatic characteristics, Java is the most exposed regions to landslide hazard and closely related to several factors: (1) located on a subduction zone, 60% of Java is mountainous, with volcano-tectonic mountain chains and 36 active volcanoes out of the 129 in Indonesia, and these volcanic materials are intensively weathered (2) Java is under a humid tropical climate associated with heavy rainfall during the rainy season from October to April. On top of these “natural” conditions, the human activity is an additional factor of landslide occurrence, driven by a high demographic density
