Les Pennes-Mirabeau fire, August 2016 Vitrolles, Les Pennes-Mirabeau, Cabriès

Out · last detection 11 Aug 2016, 02:36 UTC

The fire started on 10 August 2016 in Les Pennes-Mirabeau, France, and satellites saw it burning for 2 days. Copernicus mapped a burnt perimeter of 3,015 hectares from satellite imagery, spread across 5 municipalities.

It is the largest fire in Bouches-du-Rhône since 2016 (of 18 with a page). The largest in France in 2016, of 11.

The power measured by the satellite is low (18.8 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

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.

Built-up area98 ha
Residents≈ 4,700

Inside the perimeter there were about 98 hectares of built-up land and about 4,700 residents (GHSL 2015, 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.

Official record

According to BDIFF, a fire of 2,663 ha was recorded in Rognac on 10 August 2016 (the satellite measured 3,015 ha). The record has no coordinates, so it was matched by municipality and date.

BDIFF (Base de Données sur les Incendies de Forêts en France). This is the agency’s consolidated statistic: it measures the area in its own way, which is why it can differ from the satellite.

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 Les Pennes-Mirabeau fire last?
Copernicus dates it between 10 August 2016 and 11 August 2016: 2 days between the first and last image with fire.
How much area did it burn?
The perimeter Copernicus measured from satellite imagery is 3,015 hectares (30.2 km²). Official national figures may differ.
Which municipalities burned?
The fire entered 5 municipalities: Vitrolles (1,749 ha, 47 %); Les Pennes-Mirabeau (827 ha, 24 %); Cabriès (200 ha, 5.4 %); Rognac (174 ha, 9.9 %); Aix-en-Provence (66 ha, 0.4 %).
Did the fire reach a town?
The fire started in Les Pennes-Mirabeau and reached its centre: the point marking it was inside the burnt area or less than 500 metres from it. That does not mean houses burned.
What was the weather like?
During the fire the temperature reached 28.8 °C, humidity dropped to 25 % and gusts hit 74 km/h. The fire danger index (FWI) reached 84, class Very extreme.
Where does this data come from?
From the EFFIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of France (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. 72 Suomi-NPP VIIRS detections on those dates.
  • Compared with BDIFF: 2,663 official ha against 3,015 ha of perimeter; they agree within 25%.
  • 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 2015, 100 m cells), summed inside the perimeter: an estimate of what was there, not a damage count.

How we build fire pages: methodology

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 ADM5 (Open Data Commons Attribution License 1.0). 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.
