Ministry of Environment and Forestry Finds 580 Hotspots in Indonesia, Most in East Nusa Tenggara (Monday, September 15, 2025)

Based on the SiPongi forest and land fire monitoring system of the Ministry of Environment and Forestry (KLHK), monitoring in the last 24 hours shows that 580 hotspots were detected in Indonesia. This number of hotspots increased by 38 points compared to the previous period.

This data is the result of Terra/Aqua, SNPP, and NOAA satellite imagery accessed on Monday (September 15, 2025) at 11:28 AM WIB. Of the 580 hotspots detected, 23 points have a high hotspot confidence level, 527 points are medium scale, and 30 points are low scale.

The hotspot confidence level is divided into 3 scales. Low scale has a range of 0 - 29, medium scale 30 - 79, and high scale 80 - 100. The higher the hotspot confidence level, the higher the likelihood of forest and land fires occurring in a particular area.

The most detected hotspots are in East Nusa Tenggara with 205 points. West Nusa Tenggara ranks second with the most hotspots, with 103 points. East Java is in third place with 55 hotspots.

A total of 54 hotspots were detected in South Sumatra, followed by Southeast Sulawesi with 17 hotspots, and East Kalimantan and Central Java each having 17 and 15 detected hotspots.

A hotspot is a coordinate point of an area that has a higher surface temperature than its surroundings, and not the number of forest and land fire incidents.

However, a large number of clustered hotspots in an area indicates the occurrence of forest and land fires. This means that hotspot data from remote sensing satellite detection is still the most effective in monitoring forest and land fires for large areas.
