Between 2012 and 2025, VIIRS detected fire in 17,680 km² of Zhejiang at least once. In an average year it detected fire in 2,320 km², ranking 22nd 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 2013, with 5,380 km² detected; the quietest was 2020, with 1,540 km². The 2021–2025 average is 47% 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.
July, August and September together hold 36% of the fire-days in the record. The single busiest day was 1 May 2013, with detections in 1,135 cells.
Ground that burns again
Of the 17,680 km² with at least one detection, 16% had detections in three or more different years.
| Years with a detection | km² | Share |
|---|---|---|
| 1 year | 11,790 | 67% |
| 2 years | 3,010 | 17% |
| 3 to 5 years | 2,010 | 11% |
| 6 to 10 years | 671 | 3.8% |
| 11 years or more | 199 | 1.1% |
The half-degree square with the most fire-days is centred at 28.75, 118.75 and holds 10% 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.
