Băile Herculane fire, 10 September 2026 Băile Herculane, Podeni
Out · last detection 20 Oct 2026, 00:41 UTC
The fire started on 10 September 2026 in Băile Herculane, Romania, and satellites saw it burning for 41 days. Copernicus mapped a burnt perimeter of 426 hectares from satellite imagery, spread across 2 municipalities.
It is the 34th largest in Caraș-Severin since 2016 (of 194 with a page). Number 9 in Romania in 2026, of 59.
The power measured by the satellite is low (24.4 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

Satellites pass a few times a day and cloud or smoke can hide the fire: a lack of detections is not an official extinction. Each country’s emergency service declares a fire contained or out.

Inside 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.

It was 2.4 times larger than the median of its twins and lasted 41 days, against 2 days.
Only 3 of its 20 twins burned more. The weather on the first day does not explain everything: the wind in the following days, the fuel and the firefighting also count. All of them had rain in the ten days after the end: the first rainy day brought a median of 3.0 mm.

How a twin is chosen
- Same area: fires that have already ended, less than 250 km from this one, since 2016.
- Same start: we compare the FWI on the first day, the minimum humidity that day and the run of days without rain before it. The slider sets how much they may differ.
- Only pages with final weather data (ERA5 reanalysis) calculated in the same way as this fire’s; agricultural and grass burns and pages with data under review are left out.
- Fires burning at the same time as this one (a week before or after) are left out: they share the same spell of weather and do not count as a precedent.
- They are sorted by similarity, and the outlines of the first five are drawn.

Frequently asked questions
- How long did the Băile Herculane fire last?
- The official perimeter only gives the start date (11 September 2026). The end comes from the heat detections inside the perimeter: it burned until 20 October 2026 (41 days from 10 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 426 hectares (4.3 km²). Official national figures may differ.
- Which municipalities burned?
- The fire entered 2 municipalities: Băile Herculane (421 ha, 6.0 %); Podeni (6 ha, 0.1 %).
- Is the Băile Herculane fire still active?
- No fire detections since 20 Oct 2026, 00:41 UTC. A lack of detections is not an official extinction.
- What was the weather like?
- During the fire the temperature reached 24.5 °C, humidity dropped to 22 % and gusts hit 59 km/h. The fire danger index (FWI) reached 29, 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.
- How did the fires that started in similar weather in this area end?
- Fires less than 250 km away that started since 2016 with a similar FWI, humidity and dry spell: 20. Their median duration was 2 days and their median area 174 ha; 5 % went past 1,000 ha. Only 3 of its 20 twins burned more. The weather on the first day does not explain everything: the wind in the following days, the fuel and the firefighting also count. All of them had rain in the ten days after the end: the first rainy day brought a median of 3.0 mm.
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. 59 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.
