The Hot Mudflow disaster in Sidoarjo was happened for the first time on 29 May 2006. It's been 4 years, but until now the hot mud doesn't seems to stop flowing out from beneath of earth surface. On the other hand, this disaster causes various effects. There are some physical effects that occurs due to this disaster such as, existence of a pool of mud in the surface, land subsidence around the center of explosion, the emergence of cracks and bubbles around the center of explosion, and water and air pollution. Besides that, this disaster also causes the other effects that can not be seen physically, the increasement of crime and unemployment. The availability of information that contain about these effects and the affected areas is really important. In this research, map of affected areas that contained land use and land cover changes and land subsidence information will be done. Identification of land use changes can be done by multitemporal satellite imagery interpretating. Identification of land subsidence can be done by GPS survey. Based on the result, land use and land cover changes occur only in areas that covered by a pool of hot mud and land subsidence was happened widespread until several kilometers from the center of explosion.
