Between 2012 and 2025, VIIRS detected fire in 245 km² of Pernik at least once. In an average year it detected fire in 22 km², ranking 23rd of 28 regions of Bulgaria.
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 2012, with 51 km² detected; the quietest was 2023, with 6.4 km². The 2021–2025 average is 50% 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.
July, August and September together hold 42% of the fire-days in the record. The single busiest day was 27 July 2025, with detections in 9 cells.
Ground that burns again
Of the 245 km² with at least one detection, 3.7% had detections in three or more different years.
| Years with a detection | km² | Share |
|---|---|---|
| 1 year | 216 | 88% |
| 2 years | 20 | 8.2% |
| 3 to 5 years | 7.3 | 3.0% |
| 6 to 10 years | 0.0 | 0.0% |
| 11 years or more | 1.8 | 0.7% |
The half-degree square with the most fire-days is centred at 42.75, 23.25 and holds 51% 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.
