Between 2012 and 2025, VIIRS detected fire in 15,060 km² of Houaphanh at least once. In an average year it detected fire in 5,370 km², ranking 5th of 17 regions of Lao PDR.
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 2023, with 8,440 km² detected; the quietest was 2017, with 4,010 km². The 2021–2025 average is 6.1% higher 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 90% of the fire-days in the record. The single busiest day was 6 April 2023, with detections in 959 cells.
Ground that burns again
Of the 15,060 km² with at least one detection, 76% had detections in three or more different years.
| Years with a detection | km² | Share |
|---|---|---|
| 1 year | 1,780 | 12% |
| 2 years | 1,810 | 12% |
| 3 to 5 years | 5,450 | 36% |
| 6 to 10 years | 5,340 | 35% |
| 11 years or more | 673 | 4.5% |
The half-degree square with the most fire-days is centred at 20.25, 103.75 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.
