Between 2012 and 2025, VIIRS detected fire in 144 km² of Nam Định at least once. In an average year it detected fire in 19 km², ranking 61st of 63 regions of Vietnam.
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 40 km² detected; the quietest was 2013, with 3.5 km². The 2021–2025 average is 81% 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.
May, June and July together hold 46% of the fire-days in the record. The single busiest day was 21 June 2019, with detections in 9 cells.
Ground that burns again
Of the 144 km² with at least one detection, 18% had detections in three or more different years.
| Years with a detection | km² | Share |
|---|---|---|
| 1 year | 95 | 66% |
| 2 years | 23 | 16% |
| 3 to 5 years | 19 | 13% |
| 6 to 10 years | 5.9 | 4.1% |
| 11 years or more | 1.2 | 0.8% |
The half-degree square with the most fire-days is centred at 20.25, 106.25 and holds 97% 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.
