Between 2012 and 2025, VIIRS detected fire in 104,280 km² of Rondônia at least once. In an average year it detected fire in 21,760 km², ranking 10th of 27 regions of Brazil.
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 2015, with 30,630 km² detected; the quietest was 2025, with 5,840 km². The 2021–2025 average is 17% 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.
August, September and October together hold 83% of the fire-days in the record. The single busiest day was 12 September 2015, with detections in 2,095 cells.
Ground that burns again
Of the 104,280 km² with at least one detection, 43% had detections in three or more different years.
| Years with a detection | km² | Share |
|---|---|---|
| 1 year | 38,600 | 37% |
| 2 years | 20,690 | 20% |
| 3 to 5 years | 29,910 | 29% |
| 6 to 10 years | 14,540 | 14% |
| 11 years or more | 547 | 0.5% |
The half-degree square with the most fire-days is centred at -9.75, -64.25 and holds 5.5% 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.
