This study focuses on developing FMI and TMI through looking at the MODIS data on forest fires that occurred in inaccessible areas for 2011 to 2015 years. In order to do this, 1,469 fire ignition points were extracted from 3,637 fire spots. The ratio of forest fires for each of forest types showed 59.4% (deciduous), 21.7% (evergreen), and 18.9% (mixed). In terms of altitude and aspect, the fire frequency was the highest at 56.3% under 550m and 18.9% in the southeast. The results of calculating the FMI and the TMI by the weight of the fire frequency, the deciduous forest showed FMI 10, FMI 4 in evergreen forest and mixed forest showed FMI 3. The highest TMI of 10 has an altitude index of 5.0 under 550m and a southeast aspect index of 5.0. On the other hand, the altitude index of 1,537m or more was 0.5, and the aspect index of northeast, east, and south was 1.0, which was the lowest of FMI 1.5. Thus, this study results will be useful for decision-makers to prevent forest fires in accessible areas, and when coming up with system to do intensive monitoring of the fire risk areas.
