Between 2012 and 2025, VIIRS detected fire in 10,820 km² of Biobío at least once. In an average year it detected fire in 1,440 km², ranking 2nd of 16 regions of Chile.
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 2023, with 3,280 km² detected; the quietest was 2012, with 904 km². The 2021–2025 average is 36% 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.
February, March and April together hold 50% of the fire-days in the record. The single busiest day was 4 February 2023, with detections in 1,059 cells.
Ground that burns again
Of the 10,820 km² with at least one detection, 20% had detections in three or more different years.
| Years with a detection | km² | Share |
|---|---|---|
| 1 year | 5,900 | 55% |
| 2 years | 2,710 | 25% |
| 3 to 5 years | 1,910 | 18% |
| 6 to 10 years | 282 | 2.6% |
| 11 years or more | 13 | 0.1% |
The half-degree square with the most fire-days is centred at -37.75, -72.25 and holds 17% 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.
