Between 2012 and 2025, VIIRS detected fire in 203,870 km² of Heilongjiang at least once. In an average year it detected fire in 37,120 km², ranking 1st 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 2017, with 65,410 km² detected; the quietest was 2012, with 17,710 km². The 2021–2025 average is 26% 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.
March, April and May together hold 51% of the fire-days in the record. The single busiest day was 21 April 2021, with detections in 7,284 cells.
Ground that burns again
Of the 203,870 km² with at least one detection, 40% had detections in three or more different years.
| Years with a detection | km² | Share |
|---|---|---|
| 1 year | 71,730 | 35% |
| 2 years | 49,970 | 25% |
| 3 to 5 years | 68,460 | 34% |
| 6 to 10 years | 13,310 | 6.5% |
| 11 years or more | 401 | 0.2% |
The half-degree square with the most fire-days is centred at 46.25, 126.75 and holds 2.0% 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.
