Topleț fire, September 2026 Topleț
The fire started on 29 September 2026 in Topleț, Romania, and satellites saw it burning for 12 days. Copernicus mapped a burnt perimeter of 477 hectares from satellite imagery, spread across a single municipality.
It is the 31th largest in Caraș-Severin since 2016 (of 196 with a page). Number 7 in Romania in 2026, of 59.
The power measured by the satellite is low (10.0 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

What happened to each town
-
477 ha reached on 29 Sept5.1 %
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.
What burned
- Broadleaved forest100 %
Land cover inside the perimeter according to Corine Land Cover, as reported by Copernicus.
People and buildings inside the perimeter
GHSL 2025Inside the perimeter there was no noticeable built-up land and almost nobody lived there (GHSL 2025, satellite-based estimate).
This is an estimate on 100 m cells, made from satellite imagery and census data: it does not mean that homes burned or that anyone was harmed. The perimeter also contains land that never burned. The GHSL 2025 epoch is a projection made from 2020 and earlier data.

The smoke
CAMS · CopernicusOn 8 October 2026 the air beside the fire reached 96 µg/m³ of PM2.5. That day averaged 45: 3.0 times the WHO daily guideline (15).

Frequently asked questions
- How long did the Topleț fire last?
- The official perimeter only gives the start date (4 October 2026). The end comes from the heat detections inside the perimeter: it burned until 10 October 2026 (12 days from 29 September 2026), the last day with detections before more than 10 days in a row without any, so it is approximate.
- How much area did it burn?
- The perimeter Copernicus measured from satellite imagery is 477 hectares (4.8 km²). Official national figures may differ.
- Which municipalities burned?
- The fire only entered Topleț (477 ha, 5.1 %).
- Is the Topleț fire still active?
- No fire detections since 10 Oct 2026, 00:30 UTC. A lack of detections is not an official extinction.
- Did the fire reach a town?
- The fire started in Topleț and came within 1.9 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 23.4 °C, humidity dropped to 15 % and gusts hit 37 km/h. The fire danger index (FWI) reached 32, class High.
- Where does this data come from?
- From the EFFIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Romania (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.
- The official perimeter has no end date: the end is the last day with VIIRS detections inside the perimeter before a gap of more than 10 days (150 days at most), so it is approximate. 33 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.
- Built-up area and population come from the JRC Global Human Settlement Layer (epoch 2025, 100 m cells), summed inside the perimeter: an estimate of what was there, not a damage count.
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 (Creative Commons Attribution 4.0 International (CC BY 4.0)). 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.
