How long did the Marte fire last?

GWIS (Copernicus) dates it between 9 November 2025 and 11 November 2025: 3 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 2,532 hectares (25.3 km²). It is an estimate: official national figures may differ.

Which municipalities burned?

The fire entered 2 municipalities: Marte (2,441 ha, 1.2 %); Mafa (105 ha, 0.0 %).

Where does this data come from?

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

Marte fire, 9 November 2025 Marte, Mafa

Out · last detection 11 Nov 2025, 00:11 UTC

The fire started on 9 November 2025 in Marte, Nigeria, and satellites saw it burning for 3 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 2,532 hectares from heat detections, spread across 2 municipalities.

It is the 278th largest in Borno since 2016 (of 457 with a page). Number 197 in Nigeria in 2025, of 294.

This area had burned before

81% of the perimeter overlaps earlier fires recorded since 2016: 2,242 ha in 2017, 107 ha in 2018, 293 ha in 2020, 119 ha in 2023. Part of it burned more than once, so the yearly figures add up to more than the 2,061 ha that had burned before.

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 4.0 International (CC BY 4.0)). 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.
