Dupnitsa fire, August 2024 Дупница · Dupnitsa

Out · last detection 27 Aug 2024, 12:32 UTC

The fire started on 24 August 2024 in Dupnitsa, Bulgaria, and satellites saw it burning for 4 days. Copernicus mapped a burnt perimeter of 207 hectares from satellite imagery, spread across a single municipality.

Number 38 in Bulgaria in 2024, of 62.

The power measured by the satellite is low (22.4 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

Burnt area inside each municipality, from crossing the official perimeter with administrative boundaries. The distance runs from the point marking the centre of each area to the nearest fire: staying a kilometre away does not mean it reached the houses.

Frequently asked questions

How long did the Dupnitsa fire last?
According to the heat detections seen by satellite inside the perimeter, it burned from 24 August 2024 to 27 August 2024 (4 days). The perimeter dates it from 24 August 2024 to 25 August 2024.
How much area did it burn?
The perimeter Copernicus measured from satellite imagery is 207 hectares (2.1 km²). Official national figures may differ.
Which municipalities burned?
The fire only entered Dupnitsa (207 ha, 0.6 %).
Did the fire reach a town?
The fire started in Dupnitsa and came within 9.7 km of its centre. That is the distance from the perimeter, or the nearest hotspot, to the point marking the centre; it does not mean it entered the houses.
What was the weather like?
During the fire the temperature reached 23.5 °C, humidity dropped to 27 % and gusts hit 45 km/h. The fire danger index (FWI) reached 13, class Moderate.
Where does this data come from?
From the EFFIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Bulgaria (geoBoundaries). It is not an official report.

Where to verify it

A satellite detection is not an official report. Final figures and the fire’s status are published by each country’s emergency service.

Does something look wrong on this page?

This page is built from satellite data and official records, and it sometimes gets things wrong: the wrong dates, the wrong town, two fires merged into one, or something that was not a wildfire at all. If you know this fire first-hand (you live nearby, saw it, fought it or reported on it), tell us what really happened and we will check it.

How we know this
  • Perimeter: EFFIS (Copernicus), mapped on satellite imagery.
  • Dates adjusted with the VIIRS detections inside the perimeter, which said 24 August 2024 to 25 August 2024. 31 Suomi-NPP VIIRS detections on those dates.
  • We have not matched this page with any official record.
  • Weather: Copernicus ERA5 reanalysis at the fire location, in cells of about 25 km.

Where this data comes from

The perimeter and land cover come from the Copernicus European Forest Fire Information System (EFFIS), measured on MODIS and Sentinel-2 imagery and published under CC BY 4.0. Heat detections come from the VIIRS sensors aboard Suomi-NPP and NOAA-20, distributed by NASA FIRMS at 375 m resolution. Municipal boundaries come from geoBoundaries ADM2 (Public Domain). The area per municipality is computed by WorldFires by crossing the perimeter with those boundaries, so it may differ slightly from each country’s official figure.
