Between 2012 and 2025, VIIRS detected fire in 70 km² of Harju at least once. In an average year it detected fire in 6.0 km², ranking 1st of 15 regions of Estonia.
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 2018, with 16 km² detected; the quietest was 2012, with 1.3 km². The 2021–2025 average is 11% 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 73% of the fire-days in the record. The single busiest day was 4 May 2013, with detections in 4 cells.
Ground that burns again

- 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.
