Between 2012 and 2025, VIIRS detected fire in 36,040 km² of Sichuan at least once. In an average year it detected fire in 4,620 km², ranking 15th 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 2020, with 6,780 km² detected; the quietest was 2025, with 2,970 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.
December, January and February together hold 36% of the fire-days in the record. The single busiest day was 1 February 2023, with detections in 733 cells.
Ground that burns again
Of the 36,040 km² with at least one detection, 17% had detections in three or more different years.
| Years with a detection | km² | Share |
|---|---|---|
| 1 year | 23,850 | 66% |
| 2 years | 5,960 | 17% |
| 3 to 5 years | 4,940 | 14% |
| 6 to 10 years | 950 | 2.6% |
| 11 years or more | 342 | 0.9% |
The half-degree square with the most fire-days is centred at 26.75, 101.75 and holds 20% 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.
