How long did the Sussundenga fire last?

GWIS (Copernicus) dates it between 12 October 2017 and 17 October 2017: 6 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 4,734 hectares (47.3 km²). It is an estimate: official national figures may differ.

Which municipalities burned?

The fire only entered Sussundenga (4,756 ha, 0.7 %).

What was the weather like?

During the fire the temperature reached 42.0 °C, humidity dropped to 13 % and gusts hit 37 km/h. The fire danger index (FWI) reached 45, class Very high.

Where does this data come from?

From the GWIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Mozambique (geoBoundaries). It is not an official report.

Sussundenga fire, 12 October 2017 Sussundenga

Out · last detection 17 Oct 2017, 23:13 UTC

The fire started on 12 October 2017 in Sussundenga, Mozambique, and satellites saw it burning for 6 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 4,734 hectares from heat detections, spread across a single municipality.

It is the 78th largest in Manica since 2016 (of 198 with a page). Number 72 in Mozambique in 2017, of 196.

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 (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.
