How long did the Harmanli fire last?

Copernicus dates it between 6 August 2024 and 7 August 2024: 2 days between the first and last image with fire.

How much area did it burn?

The perimeter Copernicus measured from satellite imagery is 688 hectares (6.9 km²). Official national figures may differ.

Which municipalities burned?

The fire entered 2 municipalities: Harmanli (662 ha, 1.0 %); Topolovgrad (27 ha, 0.0 %).

Did the fire reach a town?

The closest fire to a town centre came within 16.4 km of Topolovgrad. That is the distance to the perimeter or nearest hotspot; it does not mean it entered the houses.

What was the weather like?

During the fire the temperature reached 31.6 °C, humidity dropped to 27 % and gusts hit 44 km/h. The fire danger index (FWI) reached 26, class High.

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.

Harmanli fire, August 2024 Харманли · Harmanli, Topolovgrad

Out · last detection 7 Aug 2024, 00:43 UTC

The fire started on 6 August 2024 in Harmanli, Bulgaria, and satellites saw it burning for 2 days. Copernicus mapped a burnt perimeter of 688 hectares from satellite imagery, spread across 2 municipalities.

It is the 14th largest in Haskovo since 2016 (of 46 with a page). Number 11 in Bulgaria in 2024, of 62.

The power measured by the satellite is low (3.8 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

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.

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.
