How long did the Lac Iro fire last?

According to the heat detections seen by satellite, it burned from 14 October 2026 to 23 October 2026 (10 days between the first and the last detection). There is no perimeter yet to date it.

How much area did it burn?

There is no perimeter yet. Heat detections rebuild about 2,366 hectares with fire (23.7 km²), a rough figure; GWIS will give its own when it publishes the perimeter, which can take several days.

Which municipalities burned?

The fire entered 3 municipalities: Lac Iro (1,232 ha, 0.1 %); Barh-Signaka (1,036 ha, 0.0 %); Bahr-Azoum (98 ha, 0.0 %).

Is the Lac Iro fire still active?

No fire detections since 23 Oct 2026, 11:57 UTC. A lack of detections is not an official extinction.

What was the weather like?

During the fire the temperature reached 40.6 °C, humidity dropped to 11 % and gusts hit 35 km/h. The fire danger index (FWI) reached 46, class Very high.

Where does this data come from?

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

Lac Iro fire, October 2026 Lac Iro, Barh-Signaka, Bahr-Azoum

Dying down · last detection 23 Oct 2026, 11:57 UTC

Satellites first detected fire on 14 October 2026 in Lac Iro, Chad. It has been active for 10 days, with 183 heat detections and an area with fire of about 2,366 hectares rebuilt from them, spread across 3 municipalities.

GWIS (Copernicus) has not yet published the perimeter of this fire. It rebuilds it from hotspots, which can take several days, and it does not always arrive. For now the area is the one rebuilt from heat detections (about 14 hectares per pixel). If the perimeter arrives, this page picks it up on its own and keeps the same address.

Is it still active?

No detections since 23 Oct 2026, 11:57 UTC. That usually means no flame is visible from space any more, although hotspots may remain. Satellites pass a few times a day and cloud or smoke can hide the fire: a lack of detections is not an official extinction. Each country’s emergency service declares a fire contained or out.

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.
