Jokkmokk fire, 15 July 2018 Jokkmokk
The fire started on 15 July 2018 in Jokkmokk, Sweden, and satellites saw it burning for 4 days. Copernicus mapped a burnt perimeter of 104 hectares from satellite imagery, spread across a single municipality.
It is the 10th largest in Norrbottens län since 2016 (of 10 with a page). Number 25 in Sweden in 2018, of 25.
The power measured by the satellite is low (21.4 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

The weather it burned in
It had gone one day without rain (1 mm or more) when it started. Rain came after the fire: 1.3 mm on 21 Jul.

No earlier perimeters overlap this fire since 2016, when the satellite record begins.

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.

Land cover inside the perimeter according to Corine Land Cover, as reported by Copernicus.
People and buildings inside the perimeter
GHSL 2020Inside the perimeter there was no noticeable built-up land and almost nobody lived there (GHSL 2020, 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.

Frequently asked questions
- How long did the Jokkmokk fire last?
- According to the heat detections seen by satellite inside the perimeter, it burned from 15 July 2018 to 18 July 2018 (4 days). The perimeter dates it from 15 July 2018 to 16 July 2018.
- How much area did it burn?
- The perimeter Copernicus measured from satellite imagery is 104 hectares (1.0 km²). Official national figures may differ.
- Which municipalities burned?
- The fire only entered Jokkmokk (100 ha, 0.0 %).
- What was the weather like?
- During the fire the temperature reached 28.2 °C, humidity dropped to 31 % and gusts hit 37 km/h. The fire danger index (FWI) reached 18, class Moderate.
- Where does this data come from?
- From the EFFIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Sweden (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 adjusted with the VIIRS detections inside the perimeter, which said 15 July 2018 to 16 July 2018. 26 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 2020, 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 (CC0 1.0 Universal (CC0 1.0) Public Domain Dedication). 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.
