Between 2012 and 2025, VIIRS detected fire in 5,590 km² of Phayao at least once. In an average year it detected fire in 1,910 km², ranking 20th of 77 regions of Thailand.
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 2019, with 3,040 km² detected; the quietest was 2022, with 570 km². The 2021–2025 average is 25% 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 79% of the fire-days in the record. The single busiest day was 17 March 2016, with detections in 253 cells.
Ground that burns again
Of the 5,590 km² with at least one detection, 77% had detections in three or more different years.
| Years with a detection | km² | Share |
|---|---|---|
| 1 year | 666 | 12% |
| 2 years | 615 | 11% |
| 3 to 5 years | 2,170 | 39% |
| 6 to 10 years | 2,040 | 36% |
| 11 years or more | 97 | 1.7% |
The half-degree square with the most fire-days is centred at 19.25, 100.25 and holds 48% 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.
