Through the example of the Merapi volcano in Central Java in Indonesia, this talk will explore different practices and conceptions related to the comprehension and the communication with this uncertain environment. Merapi volcano is located in the “ring of fire” where Indo-Australian plate meets the Eurasian plate. At almost 3000 meter above the sea level, it is considered as permanently active. The volcano stands at 30 kilometers from the city of Yogyakarta, capital city of the eponym province. In the region, population density is quite high with 7000 inhabitant/km2 in the city and around 1000 inhabitant/km2 in the rural areas of Merapi’s south flank.
This reflection is a part of an anthropological research about the post-disaster resettlement (relokasi) of a village (dusun) located in the Merapi volcano’s south flank. Totally destroyed by the 2010 eruption of Merapi, the 81 household of the studied village was removed 5 kilometers downstream of its original location, through a post disaster governmental reconstruction program.
