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 2020, with 11,510 km² detected; the quietest was 2022, with 2,220 km². The 2021–2025 average is 43% 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.
February, March and April together hold 89% of the fire-days in the record. The single busiest day was 14 March 2015, with detections in 830 cells.
Ground that burns again
Of the 20,430 km² with at least one detection, 80% had detections in three or more different years.
| Years with a detection | km² | Share |
|---|---|---|
| 1 year | 2,000 | 10% |

- 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.
