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

People and buildings inside the perimeter

GHSL 2025
Built-up area5.4 ha
Residents≈ 400

Inside the perimeter there were about 5.4 hectares of built-up land and about 400 residents (GHSL 2025, satellite-based estimate).

This is an estimate on 100 m cells, made from satellite imagery and census data: it does not mean that homes burned or that anyone was harmed. The perimeter also contains land that never burned. The GHSL 2025 epoch is a projection made from 2020 and earlier data.

Official record

Several official records match this area

According to CONAFOR, 2 fires started inside this perimeter on these dates, totalling 921 ha (the satellite measured 1,788 ha). The two figures differ a lot, so these may not be exactly the same fire: take them as nearby records.

CONAFOR records each fire that started at a different time or place separately; the satellite sees a single burned area, so this page groups them together. The numbers on the map show where each one started.

Frequently asked questions

How long did the Miacatlán fire last?
According to the heat detections seen by satellite inside the perimeter, it burned from 24 March 2024 to 7 April 2024 (15 days). The perimeter dates it from 26 March 2024 to 7 April 2024.
How much area did it burn?
The perimeter GWIS (Copernicus) rebuilt from heat detections is 1,788 hectares (17.9 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire entered 3 municipalities: Ocuilan (1,585 ha, 4.1 %); Miacatlán (190 ha, 0.9 %); Cuernavaca (22 ha, 0.1 %).
What was the weather like?
During the fire the temperature reached 29.5 °C, humidity dropped to 4 % and gusts hit 49 km/h. The fire danger index (FWI) reached 49, class Very high.
Where does this data come from?
From the GWIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Mexico (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.

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.

How we know this
  • Perimeter: GWIS (Copernicus), rebuilt from heat detections rather than mapped on imagery.
  • Dates adjusted with the VIIRS detections inside the perimeter, which said 26 March 2024 to 7 April 2024. 106 Suomi-NPP VIIRS detections on those dates.
  • Compared with CONAFOR: 921 official ha against 1,788 ha of perimeter; similar, but with reservations.
  • Weather: Copernicus ERA5 reanalysis at the fire location, in cells of about 25 km.
  • Built-up area and population come from the JRC Global Human Settlement Layer (epoch 2025, 100 m cells), summed inside the perimeter: an estimate of what was there, not a damage count.

How we build fire pages: methodology ›

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 (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.
