Indonesia's hotspots over 90 days: how far did they spread?

Explore daily NOAA-20 hotspot detections over 90 days and see how many regencies and provinces had stored detections.

This map plays NOAA-20 satellite hotspot detections one day at a time. Each circle represents a map cell with detections on that day. Move the date control to stop on a day, or press Play to watch the whole record.

Bright dots show detections in an approximately 28 km cell on one day: yellow 1–9, orange 10–49, red 50 or more. They fade after five days. Dim footprints mark approximately 111 km cells where a detection occurred by the selected date. Colour does not show severity.

From August 4, 2026 to November 1, 2026, 166,600 detections were recorded in Indonesian city or regency areas. Detections occurred in 425 of 514 cities and regencies across 38 of 38 provinces. These figures describe the spread of the satellite record, not a count of separate fires.

Areas with the most detections

  5. Kapuas · Kalimantan Tengah9,009

The peak day in this record was October 14, 2026, with 12,522 detections in 263 cities and regencies across 35 provinces.

How confident is the sensor?

The VIIRS sensor assigns each detection one of three confidence classes: low, moderate, or high. The percentage ranges below follow SiPongi, Indonesia's Ministry of Forestry wildfire early detection system.

  • Low · 0–29%8,258
  • Moderate · 30–79%153,291
  • High · 80–100%5,051

Confidence describes how sure the sensor is that it detected a fire. It does not measure burned area or danger.

How to read a hotspot

  • One dot is a 375-metre pixel. One large fire may produce many detections.
  • It may not be a wildfire. Burning crop residues or industrial chimneys may also be detected.
  • The satellite passes twice a day, around midday and midnight. A fire starting and ending between passes may be missed.
  • No dot does not mean no fire. Cloud and thick smoke can conceal heat.

How severe is the fire?

The hotspot map shows where and when the satellite detected heat. One fire can produce several detections, and other heat sources can also appear as hotspots. These counts therefore do not equal the number of fires or the area burned. The data show where heat was indicated but cannot establish the extent of damage.

This record uses one satellite, NOAA-20, so detections from multiple satellites are not added together and double counted. Area boundaries follow the stored Indonesian city and regency map.

Source: NASA LANCE FIRMS, VIIRS NOAA-20 instrument. Period: August 4, 2026–November 1, 2026 WIB. Map circles represent cells about 28 km (0.25°) across; circle size follows detection counts in each cell on the selected day.

64 days have no stored detection record. They are marked unavailable and are not counted as zero.
