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 2016, with 59 km² detected; the quietest was 2020, with 25 km². The 2021–2025 average is 12% 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.
September, October and November together hold 41% of the fire-days in the record. The single busiest day was 10 March 2016, with detections in 6 cells.
Ground that burns again
Of the 211 km² with at least one detection, 40% had detections in three or more different years.

- 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.
