Between 2012 and 2025, VIIRS detected fire in 10,200 km² of Sơn La at least once. In an average year it detected fire in 3,100 km², ranking 4th of 63 regions of Vietnam.
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 5,450 km² detected; the quietest was 2022, with 1,420 km². The 2021–2025 average is 51% 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.
February, March and April together hold 85% of the fire-days in the record. The single busiest day was 6 March 2012, with detections in 546 cells.
Ground that burns again
Of the 10,200 km² with at least one detection, 62% had detections in three or more different years.
| Years with a detection | km² | Share |
|---|---|---|
| 1 year | 2,140 | 21% |
| 2 years | 1,690 | 17% |
| 3 to 5 years | 3,290 | 32% |
| 6 to 10 years | 2,630 | 26% |
| 11 years or more | 446 | 4.4% |
The half-degree square with the most fire-days is centred at 21.25, 104.25 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.
