Abstract
The northern railway of Cirebon-Semarang route is vulnerable for natural hazards such as flooding and subsidence as it is located close to the coastal area and has complex geomorphological condition. This study aims to identify and map the potential of natural hazards that can affect the Cirebon-Semarang railway by using a Geographic Information System (GIS). The valuation method used the landscape analysis approach used to determine the disaster vulnerability level. To make the GIS maps, topographic maps and geological maps of BAKORTANAL or BIG (Geospatial Information Agency) and the Geological Research and Development Center were used as the main sources. The results showed that the geomorphological conditions of the Cirebon-Semarang railway line predominantly had structural, marine and alluvial landforms which identified the high potential for flood and depression in the study area
