Between 2012 and 2025, VIIRS detected fire in 33,200 km² of Jiangsu at least once. In an average year it detected fire in 3,870 km², ranking 18th 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 2012, with 10,860 km² detected; the quietest was 2021, with 2,220 km². The 2021–2025 average is 59% 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.
April, May and June together hold 37% of the fire-days in the record. The single busiest day was 13 June 2012, with detections in 2,915 cells.
Ground that burns again
Of the 33,200 km² with at least one detection, 12% had detections in three or more different years.
| Years with a detection | km² | Share |
|---|---|---|
| 1 year | 22,410 | 67% |
| 2 years | 6,780 | 20% |
| 3 to 5 years | 3,190 | 10% |
| 6 to 10 years | 612 | 1.8% |
| 11 years or more | 214 | 0.6% |
The half-degree square with the most fire-days is centred at 31.75, 120.75 and holds 11% 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.
