Morondava fire, 27 August 2016 Morondava

Out · last detection 7 Sept 2016, 10:14 UTC

The fire started on 27 August 2016 in Morondava, Madagascar, and satellites saw it burning for 12 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 4,426 hectares from heat detections, spread across a single municipality.

It is the 20th largest in Menabe since 2016 (of 98 with a page). Number 10 in Madagascar in 2016, of 59.

Frequently asked questions

How long did the Morondava fire last?
GWIS (Copernicus) dates it between 27 August 2016 and 7 September 2016: 12 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 4,426 hectares (44.3 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire only entered Morondava (4,459 ha, 0.8 %).
What was the weather like?
During the fire the temperature reached 31.9 °C, humidity dropped to 20 % and gusts hit 53 km/h. The fire danger index (FWI) reached 52, class Extreme.
Where does this data come from?
From the GWIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Madagascar (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 (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.
