Between 2012 and 2025, VIIRS detected fire in 118 km² of Uusimaa at least once. In an average year it detected fire in 14 km², ranking 1st 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 2017, with 21 km² detected; the quietest was 2025, with 8.6 km². The 2021–2025 average is 19% 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.
April, May and June together hold 46% of the fire-days in the record. The single busiest day was 26 July 2017, with detections in 7 cells.
Ground that burns again
Of the 118 km² with at least one detection, 6.2% had detections in three or more different years.
| Years with a detection | km² | Share |
|---|---|---|
| 1 year | 102 | 86% |
| 2 years | 9.2 | 7.8% |
| 3 to 5 years | 0.0 | 0.0% |
| 6 to 10 years | 3.0 | 2.5% |
| 11 years or more | 4.3 | 3.6% |
The half-degree square with the most fire-days is centred at 60.25, 25.75 and holds 60% 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.
