Between 2012 and 2025, VIIRS detected fire in 6,500 km² of Phrae at least once. In an average year it detected fire in 2,630 km², ranking 14th 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 3,930 km² detected; the quietest was 2022, with 1,290 km². The 2021–2025 average is 20% 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 81% of the fire-days in the record. The single busiest day was 17 March 2016, with detections in 326 cells.
Ground that burns again
Of the 6,500 km² with at least one detection, 85% had detections in three or more different years.
| Years with a detection | km² | Share |
|---|---|---|
| 1 year | 413 | 6.4% |
| 2 years | 566 | 8.7% |
| 3 to 5 years | 2,240 | 35% |
| 6 to 10 years | 2,930 | 45% |
| 11 years or more | 346 | 5.3% |
The half-degree square with the most fire-days is centred at 18.25, 100.25 and holds 41% 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.
