How long did the Ankazobe fire last?

GWIS (Copernicus) dates it between 10 September 2024 and 13 September 2024: 4 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 2,057 hectares (20.6 km²). It is an estimate: official national figures may differ.

Which municipalities burned?

The fire only entered Ankazobe (2,068 ha, 0.3 %).

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.

Ankazobe fire, September 2024 Ankazobe

Out · last detection 14 Sept 2024, 09:55 UTC

The fire started on 10 September 2024 in Ankazobe, Madagascar, and satellites saw it burning for 4 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 2,057 hectares from heat detections, spread across a single municipality.

It is the 21th largest in Analamanga since 2016 (of 22 with a page). Number 52 in Madagascar in 2024, of 54.

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.
