Ministry of Environment and Forestry: Number of Hotspots in Indonesia Reaches 443 in Last 24 Hours (Wednesday, January 21, 2026)

Based on the SiPongi forest and land fire monitoring system of the Ministry of Environment and Forestry (KLHK), monitoring in the last 24 hours showed 443 hotspots detected in Indonesia. This number of hotspots decreased by 84 points compared to the previous period.

The data is the result of Terra/Aqua, SNPP, and NOAA satellite imaging accessed on Wednesday (1/21/2026) at 11:02 AM WIB. Of the 443 detected hotspots, 2 points have a high hotspot confidence level, 438 points are at a medium scale, and 3 points are at a low scale.

Hotspot confidence levels are divided into 3 scales. A low scale has a range of 0 - 29, a medium scale 30 - 79, and a 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 highest number of detected hotspots was in West Kalimantan with 139 points. Central Kalimantan ranked second with 134 hotspots. North Maluku was in third place with 26 hotspots.

As many as 20 hotspots were detected in East Kalimantan, followed by South Sulawesi with 19 hotspots, and Aceh and Bangka Belitung Islands each had 19 and 11 detected hotspots.

A hotspot is a coordinate point of an area that has a higher surface temperature compared to 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 for monitoring forest and land fires over a large area.
