Mitre fire, January 2025 Mitre

Out · last detection 15 Jan 2025, 05:49 UTC

The fire started on 11 January 2025 in Mitre, Argentina, and satellites saw it burning for 5 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 1,709 hectares from heat detections, spread across a single municipality.

It is the 227th largest in Santiago del Estero since 2016 (of 320 with a page). Number 165 in Argentina in 2025, of 206.

The power measured by the satellite is low (26.0 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

It had gone 3 days without rain (1 mm or more) when it started. Rain came after the fire: 1.2 mm on 18 Jan.

This area had burned before

68% of the perimeter overlaps earlier fires recorded since 2016: 88 ha in 2017, 1 ha in 2018, 1,017 ha in 2020, 352 ha in 2022. Part of it burned more than once, so the yearly figures add up to more than the 1,166 ha that had burned before.

Burnt area inside each municipality, from crossing the GWIS perimeter with administrative boundaries. The distance is from the town centre to the nearest fire: staying a kilometre away does not mean it reached the houses.

ECMWF ERA5 reanalysis at the fire location, the standard reference for past weather, and the Canadian Fire Weather Index (the same system Copernicus uses), computed by WorldFires from that data. Days after the fire run until the first rain.

The smoke

CAMS · Copernicus

On 10 January 2025 the air beside the fire reached 17 µg/m³ of PM2.5, but no daily average passed the WHO guideline (15).

Frequently asked questions

How long did the Mitre fire last?
GWIS (Copernicus) dates it between 11 January 2025 and 15 January 2025: 5 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 1,709 hectares (17.1 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire only entered Mitre (1,717 ha, 0.5 %).
What was the weather like?
During the fire the temperature reached 39.5 °C, humidity dropped to 19 % and gusts hit 40 km/h. The fire danger index (FWI) reached 31, class High.
Where does this data come from?
From the GWIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Argentina (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.
