Orkadiere fire, November 2016 Orkadiere

Out · last detection 23 Nov 2016, 14:44 UTC

The fire started on 21 November 2016 in Orkadiere, Senegal, and satellites saw it burning for 3 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 2,810 hectares from heat detections, spread across a single municipality.

It is the 46th largest in Matam since 2016 (of 95 with a page). Number 20 in Senegal in 2016, of 58.

The power measured by the satellite is low (11.6 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 GWIS 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.

Frequently asked questions

How long did the Orkadiere fire last?
GWIS (Copernicus) dates it between 21 November 2016 and 23 November 2016: 3 days between the first and last heat detection of the perimeter.
How much area did it burn?
The perimeter GWIS (Copernicus) rebuilt from heat detections is 2,810 hectares (28.1 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire only entered Orkadiere (2,824 ha, 1.1 %).
What was the weather like?
During the fire the temperature reached 37.6 °C, humidity dropped to 14 % and gusts hit 35 km/h. The fire danger index (FWI) reached 50, class Very high.
Where does this data come from?
From the GWIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Senegal (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: 18

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.

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 18.

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.
