Lumaco fire, February 2025 Lumaco, Galvarino
The fire started on 10 February 2025 in Lumaco, Chile, and satellites saw it burning for 3 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 1,274 hectares from heat detections, spread across 2 municipalities.
It is the 107th largest in Región de La Araucanía since 2016 (of 159 with a page). Number 22 in Chile in 2025, of 39.

Where it burned
How it evolved, day by day
Fire radiative power detected each day, in megawatts, and number of hotspots. The magenta bar marks the peak day.
The weather it burned in
It had gone 17 days without rain (1 mm or more) when it started.
This area had burned before
61% of the perimeter overlaps earlier fires recorded since 2016: 361 ha in 2019, 569 ha in 2022. Part of it burned more than once, so the yearly figures add up to more than the 776 ha that had burned before.

Burnt area inside each municipality, from crossing the GWIS 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.
People and buildings inside the perimeter
GHSL 2025Inside the perimeter there were about 1.0 hectares of built-up land and about 40 residents (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 12 February 2025 the air beside the fire reached 55 µg/m³ of PM2.5. That day averaged 29: 1.9 times the WHO daily guideline (15).

Frequently asked questions
- How long did the Lumaco fire last?
- According to the heat detections seen by satellite inside the perimeter, it burned from 10 February 2025 to 12 February 2025 (3 days). The perimeter dates it from 10 February 2025 to 11 February 2025.
- How much area did it burn?
- The perimeter GWIS (Copernicus) rebuilt from heat detections is 1,274 hectares (12.7 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire entered 2 municipalities: Lumaco (1,273 ha, 1.1 %); Galvarino (4 ha, 0.0 %).
- What was the weather like?
- During the fire the temperature reached 23.3 °C, humidity dropped to 36 % and gusts hit 49 km/h. The fire danger index (FWI) reached 28, class High.
- Where does this data come from?
- From the GWIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Chile (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: GWIS (Copernicus), rebuilt from heat detections rather than mapped on imagery.
- Dates adjusted with the VIIRS detections inside the perimeter, which said 10 February 2025 to 11 February 2025. 56 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 comes from the Copernicus Global Wildfire Information System (GWIS), which rebuilds it from MODIS and VIIRS heat detections and publishes it under CC BY 4.0. It is not measured on imagery as in Europe, so it is an estimate. 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 ADM3 (Creative Commons Attribution 3.0 Intergovernmental Organisations (CC BY 3.0 IGO)). The area per municipality is computed by WorldFires by crossing the perimeter with those boundaries, so it may differ from each country’s official figure.
