Description :
Yogyakarta urban area is located in Central Java on the fluvio-volcanic plain beside Merapi volcano. Since the last eruption of Merapi in November 1994, the Code river, which goes across this city, is particularly threatened by lahars. A detailed hazard map (1/2,000 scale) is drawn, based on morphometric surveys of the Code channel and on 4 scenarios of discharge. An additional risk assessment revealed that about 13,000 people live at risk along this river. However, the risk level varies between the urban suburbs.
