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 727 km² detected; the quietest was 2025, with 218 km². The 2021–2025 average is 28% lower than the 2012–2016 average.
Through the year

- 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.
