Luchazes fire, 11 September 2017 Luchazes

Out · last detection 21 Sept 2017, 11:51 UTC

The fire started on 11 September 2017 in Luchazes, Angola, and satellites saw it burning for 11 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 9,053 hectares from heat detections, spread across a single municipality.

It is the 18th largest in Moxico since 2016 (of 108 with a page). Number 41 in Angola in 2017, of 158.

Frequently asked questions

How long did the Luchazes fire last?
GWIS (Copernicus) dates it between 11 September 2017 and 21 September 2017: 11 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 9,053 hectares (90.5 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire only entered Luchazes (9,131 ha, 0.2 %).
What was the weather like?
During the fire the temperature reached 35.8 °C, humidity dropped to 10 % and gusts hit 50 km/h. The fire danger index (FWI) reached 61, class Extreme.
Where does this data come from?
From the GWIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Angola (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.

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 geoBoundaries ADM2 (Public Domain). 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.
