Varshets fire, March 2019 Вършец · Varshets
The fire started on 27 March 2019 in Varshets, Bulgaria, and satellites saw it burning for 2 days. Copernicus mapped a burnt perimeter of 263 hectares from satellite imagery, spread across a single municipality.
It is the 7th largest in Montana since 2016 (of 19 with a page). Number 12 in Bulgaria in 2019, of 42.
The power measured by the satellite is low (6.6 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.

The weather day by day
ECMWF ERA5 reanalysis at the fire location, the standard reference for past weather, and the Canadian Fire Weather Index (the same system Copernicus uses), computed by WorldFires from that data. Days after the fire run until the first rain.

The smoke
CAMS · CopernicusOn 26 March 2019 the air beside the fire reached 28 µg/m³ of PM2.5. That day averaged 17: 1.1 times the WHO daily guideline (15).

Frequently asked questions
- How long did the Varshets fire last?
- Copernicus dates it between 27 March 2019 and 28 March 2019: 2 days between the first and last image with fire.
- How much area did it burn?
- The perimeter Copernicus measured from satellite imagery is 263 hectares (2.6 km²). Official national figures may differ.
- Which municipalities burned?
- The fire only entered Varshets (263 ha, 1.1 %).
- Did the fire reach a town?
- The fire started in Varshets and came within 8.9 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 12.7 °C, humidity dropped to 34 % and gusts hit 37 km/h. The fire danger index (FWI) reached 9, class Low.
- 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 from the perimeter: the VIIRS detections inside it did not change them. 7 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.
