Between 2012 and 2025, VIIRS detected fire in 6,000 km² of Hainan at least once. In an average year it detected fire in 790 km², ranking 27th 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 2015, with 1,740 km² detected; the quietest was 2022, with 365 km². The 2021–2025 average is 35% 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 42% of the fire-days in the record. The single busiest day was 4 April 2015, with detections in 132 cells.
Ground that burns again
Of the 6,000 km² with at least one detection, 21% had detections in three or more different years.
| Years with a detection | km² | Share |
|---|---|---|
| 1 year | 3,680 | 61% |
| 2 years | 1,090 | 18% |
| 3 to 5 years | 1,030 | 17% |
| 6 to 10 years | 192 | 3.2% |
| 11 years or more | 8.1 | 0.1% |
The half-degree square with the most fire-days is centred at 19.25, 108.75 and holds 40% 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.
