Between 2012 and 2025, VIIRS detected fire in 32,930 km² of Riau at least once. In an average year it detected fire in 5,370 km², ranking 7th of 33 regions of Indonesia.
Year by year
Detected area per year, km². Area of 0.01° cells with at least one detection in the year.
The busiest year was 2014, with 15,630 km² detected; the quietest was 2022, with 926 km². The 2021–2025 average is 89% lower than the 2012–2016 average.
Through the year
Share of all fire-days 2012–2025 by month. A fire-day is one cell with a detection on one day.
June, July and August together hold 49% of the fire-days in the record. The single busiest day was 20 June 2013, with detections in 2,938 cells.
Ground that burns again
Of the 32,930 km² with at least one detection, 34% had detections in three or more different years.
| Years with a detection | km² | Share |
|---|---|---|
| 1 year | 14,000 | 43% |
| 2 years | 7,800 | 24% |
| 3 to 5 years | 9,610 | 29% |
| 6 to 10 years | 1,490 | 4.5% |
| 11 years or more | 35 | 0.1% |
The half-degree square with the most fire-days is centred at 1.75, 101.25 and holds 7.7% of the region's fire-days.

- How these figures are madeDetected area, cells, and the single-satellite record.
Detected area counts every 0.01° cell with at least one VIIRS detection, so a small fire counts as a whole cell and a fire missed by cloud or between passes is absent. Borders: Natural Earth 1:10m. 2012 begins on 20 January.
