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.

Official record

According to EGIF (MITECO), this fire started on 20 September 2017 and burned 1,826 ha (the satellite measured 1,561 ha).

Frequently asked questions

How long did the Tejeda fire last?
Copernicus dates it between 20 September 2017 and 21 September 2017: 2 days between the first and last image with fire. According to EGIF (MITECO), it was detected on 20 September 2017 at 14:00 and declared extinguished on 30 September 2017.
How much area did it burn?
The perimeter Copernicus measured from satellite imagery is 1,561 hectares (15.6 km²). Official national figures may differ.
Which municipalities burned?
The fire entered 6 municipalities: Vega de San Mateo (887 ha, 23 %); Tejeda (272 ha, 2.6 %); San Bartolomé de Tirajana (206 ha, 0.6 %); Santa Lucía de Tirajana (106 ha, 1.7 %); Valsequillo de Gran Canaria (56 ha, 1.4 %); Agüimes (41 ha, 0.5 %).
Did the fire reach a town?
The closest fire to a town centre came within 0.6 km of Tejeda. 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 15.1 °C, humidity dropped to 59 % and gusts hit 52 km/h. The fire danger index (FWI) reached 16, class Moderate.
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.

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.

What do you think is wrong?

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.

How we know this
  • Perimeter: EFFIS (Copernicus), mapped on satellite imagery.
  • Dates from the perimeter: the VIIRS detections inside it did not change them. 44 Suomi-NPP VIIRS detections on those dates.
  • Compared with EGIF (MITECO): 1,826 official ha against 1,561 ha of perimeter; they agree within 25%.
  • Checked against news and agencies: 4 confirmed sources.
  • 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.
