Between 2012 and 2025, VIIRS detected fire in 112 km² of Northern Ostrobothnia at least once. In an average year it detected fire in 13 km², ranking 4th of 18 regions of Finland.
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 2014, with 21 km² detected; the quietest was 2012, with 6.9 km². The 2021–2025 average is within 5% of 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.
July, August and September together hold 39% of the fire-days in the record. The single busiest day was 28 July 2021, with detections in 12 cells.
Ground that burns again
Of the 112 km² with at least one detection, 6.2% had detections in three or more different years.
| Years with a detection | km² | Share |
|---|---|---|
| 1 year | 101 | 90% |
| 2 years | 3.8 | 3.4% |
| 3 to 5 years | 2.1 | 1.9% |
| 6 to 10 years | 0.0 | 0.0% |
| 11 years or more | 4.8 | 4.3% |
The half-degree square with the most fire-days is centred at 64.75, 24.25 and holds 95% 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.
