The occurrence of a great forest fire in Indonesia in this summer gave impacts on various phases in social and economic activities. The smog caused by the fire influences neighboring countries in addition to Indonesia. To prevent the damage area extending, we need to get information about present conditions on the disaster. However, since a target area is broad in this case, it's difficult to get needed information.<BR>We have used Defense Meteorological Satellite Program (DMSP) and Geostationary Meteorological Satellite (GMS) to monitor this disaster. DMSP detects slight emission such as fires at night and GMS collects data on cloud every hour. By using two different types of satellite data, we can get information on the location of hot spots and spread of smog caused by the fire. Time sequential data we have processed from GMS clarifies movement of the smog. From DMSP, we can detect the locations of hot spots.<BR>On September 21, there were many hot spots in the southern part of the Kalimantan Island. On September 30, however, a number of the hot spots in that area became smaller. On the other hand, a number of hot spots in the Sumatra Island didn't change for more than 10 days. Smog generated in the Kalimantan Island moves westward; Singapore, Malaysia, and so on. The spread of smog still remains as of September 30.<BR>As mentioned, by using two satellites of different characteristic, we can clarify the change in conditions of the hot snots and the movement of smoe venerated by the fire.
