Teteven fire, 9 March 2025 Тетевен · Teteven

Out · last detection 9 Mar 2025, 00:30 UTC

The fire started on 9 March 2025 in Teteven, Bulgaria, and satellites saw it burning for 1 day. Copernicus mapped a burnt perimeter of 102 hectares from satellite imagery, spread across a single municipality.

It is the 49th largest in Lovech since 2016 (of 52 with a page). Number 43 in Bulgaria in 2025, of 44.

The power measured by the satellite is low (4.1 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

It had gone 6 days without rain (1 mm or more) when it started. Rain came after the fire: 1.2 mm on 13 Mar.

This area had burned before

97% of the perimeter overlaps earlier fires recorded since 2016: 79 ha in 2021, 96 ha in 2023. Part of it burned more than once, so the yearly figures add up to more than the 99 ha that had burned before.

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

Frequently asked questions

How long did the Teteven fire last?
Copernicus dates it between 9 March 2025 and 9 March 2025: 1 day between the first and last image with fire.
How much area did it burn?
The perimeter Copernicus measured from satellite imagery is 102 hectares (1.0 km²). Official national figures may differ.
Which municipalities burned?
The fire only entered Teteven (102 ha, 0.2 %).
Did the fire reach a town?
The closest fire to a town centre came within 13.4 km of Teteven. 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 16.9 °C, humidity dropped to 21 % and gusts hit 17 km/h. The fire danger index (FWI) reached 5, 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.

Emergency number: 112

Satellite cross-check

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.

We will only use your email to reply about this report. Privacy. This is not an emergency service: if there is a fire now, call 112.

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.
