Between 2012 and 2025, VIIRS detected fire in 50,630 km² of Chaco at least once. In an average year it detected fire in 8,420 km², ranking 4th of 24 regions of Argentina.
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 2020, with 19,910 km² detected; the quietest was 2015, with 6,240 km². The 2021–2025 average is within 5% of 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 59% of the fire-days in the record. The single busiest day was 30 September 2020, with detections in 1,312 cells.
Ground that burns again
Of the 50,630 km² with at least one detection, 34% had detections in three or more different years.
| Years with a detection | km² | Share |
|---|---|---|
| 1 year | 20,820 | 41% |
| 2 years | 12,640 | 25% |
| 3 to 5 years | 14,370 | 28% |
| 6 to 10 years | 2,750 | 5.4% |
| 11 years or more | 43 | 0.1% |
The half-degree square with the most fire-days is centred at -26.25, -61.25 and holds 6.1% 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.
