Mashare fire, 13 September 2018 Mashare

Out · last detection 18 Sept 2018, 12:02 UTC

The fire started on 13 September 2018 in Mashare, Namibia, and satellites saw it burning for 5 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 2,990 hectares from heat detections, spread across a single municipality.

It is the 213th largest in Kavango East since 2016 (of 394 with a page). Number 44 in Namibia in 2018, of 83.

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 Mashare fire last?
GWIS (Copernicus) dates it between 13 September 2018 and 17 September 2018: 5 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 2,990 hectares (29.9 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire only entered Mashare (3,008 ha, 0.3 %).
What was the weather like?
During the fire the temperature reached 36.3 °C, humidity dropped to 6 % and gusts hit 42 km/h. The fire danger index (FWI) reached 62, class Extreme.
Where does this data come from?
From the GWIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Namibia (OCHA COD-AB). 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.

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.

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 OCHA COD-AB (Namibia Statistics Agency (NSA)) (Creative Commons Attribution for Intergovernmental Organisations (CC BY-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.
