Between 2012 and 2025, VIIRS detected fire in 16,050 km² of Diana at least once. In an average year it detected fire in 5,080 km², ranking 15th of 22 regions of Madagascar.
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 2013, with 6,440 km² detected; the quietest was 2017, with 4,160 km². The 2021–2025 average is 22% 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.
September, October and November together hold 76% of the fire-days in the record. The single busiest day was 8 November 2013, with detections in 294 cells.
Ground that burns again
Of the 16,050 km² with at least one detection, 71% had detections in three or more different years.
| Years with a detection | km² | Share |
|---|---|---|
| 1 year | 2,340 | 15% |
| 2 years | 2,340 | 15% |
| 3 to 5 years | 6,340 | 40% |
| 6 to 10 years | 4,560 | 28% |
| 11 years or more | 472 | 2.9% |
The half-degree square with the most fire-days is centred at -12.75, 49.25 and holds 16% 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.
