Between 2012 and 2025, VIIRS detected fire in 55,180 km² of Hunan at least once. In an average year it detected fire in 6,050 km², ranking 10th of 31 regions of China.
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 12,110 km² detected; the quietest was 2020, with 2,540 km². The 2021–2025 average is 48% 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.
January, February and March together hold 37% of the fire-days in the record. The single busiest day was 3 April 2012, with detections in 1,974 cells.
Ground that burns again
Of the 55,180 km² with at least one detection, 12% had detections in three or more different years.
| Years with a detection | km² | Share |
|---|---|---|
| 1 year | 37,360 | 68% |
| 2 years | 11,450 | 21% |
| 3 to 5 years | 5,830 | 11% |
| 6 to 10 years | 421 | 0.8% |
| 11 years or more | 124 | 0.2% |
The half-degree square with the most fire-days is centred at 27.75, 111.75 and holds 6.5% 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.
