Chandrexa de Queixa fire, August 2017 Chandrexa de Queixa
The fire started on 23 August 2017 in Chandrexa de Queixa, Spain, and satellites saw it burning for 2 days. Copernicus mapped a burnt perimeter of 394 hectares from satellite imagery, spread across a single municipality. According to EGIF (MITECO), it was detected on 22 August 2017 at 19:34 and declared extinguished on 26 August 2017.

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.

Official record
According to EGIF (MITECO), this fire started on 22 August 2017 and burned 448 ha (the satellite measured 394 ha).

MITECO, Estadística General de Incendios Forestales (EGIF). This is the agency’s consolidated statistic: it measures the area in its own way, which is why it can differ from the satellite.
The weather day by day
ECMWF ERA5 reanalysis at the fire location, the standard reference for past weather, and the Canadian Fire Weather Index (the same system Copernicus uses), computed by WorldFires from that data. Days after the fire run until the first rain.

The smoke
CAMS · CopernicusOn 24 August 2017 the air beside the fire reached 18 µg/m³ of PM2.5, but no daily average passed the WHO guideline (15).
Particles from the Copernicus CAMS model at the centre of the perimeter; these are not measurements in each town. The pale bar is the worst hour, the solid one the daily average.

Frequently asked questions
- How long did the Chandrexa de Queixa fire last?
- Copernicus dates it between 23 August 2017 and 24 August 2017: 2 days between the first and last image with fire. According to EGIF (MITECO), it was detected on 22 August 2017 at 19:34 and declared extinguished on 26 August 2017.
- How much area did it burn?
- The perimeter Copernicus measured from satellite imagery is 394 hectares (3.9 km²). Official national figures may differ.
- Which municipalities burned?
- The fire only entered Chandrexa de Queixa (394 ha, 2.3 %).
- Did the fire reach a town?
- The fire started in Chandrexa de Queixa and came within 2.0 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 24.8 °C, humidity dropped to 32 % and gusts hit 34 km/h. The fire danger index (FWI) reached 28, class High.
- Where does this data come from?
- From the EFFIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Spain (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.
- Dates from the perimeter: the VIIRS detections inside it did not change them. 28 Suomi-NPP VIIRS detections on those dates.
- Compared with EGIF (MITECO): 448 official ha against 394 ha of perimeter; they agree within 25%.
- Weather: Copernicus ERA5 reanalysis at the fire location, in cells of about 25 km.
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 ADM3 (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.
