Sahuaripa fire, April 2022 Sahuaripa, Madera, Temósachic
The fire started on 24 April 2022 in Sahuaripa, Mexico, and satellites saw it burning for 17 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 11,347 hectares from heat detections, spread across 3 municipalities.
It is the 12th largest in Sonora since 2016 (of 83 with a page). Number 11 in Mexico in 2022, of 232.

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 2020Inside the perimeter there were about 0.21 hectares of built-up land and almost nobody lived there (GHSL 2020, 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.

Several official records match this area
According to CONAFOR, 2 fires started inside this perimeter on these dates, totalling 8,867 ha (the satellite measured 11,347 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 Sahuaripa fire last?
- According to the heat detections seen by satellite inside the perimeter, it burned from 24 April 2022 to 10 May 2022 (17 days). The perimeter dates it from 25 April 2022 to 10 May 2022.
- How much area did it burn?
- The perimeter GWIS (Copernicus) rebuilt from heat detections is 11,347 hectares (113.5 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire entered 3 municipalities: Sahuaripa (7,276 ha, 1.4 %); Madera (3,239 ha, 0.4 %); Temósachic (831 ha, 0.2 %).
- What was the weather like?
- During the fire the temperature reached 30.2 °C, humidity dropped to 10 % and gusts hit 58 km/h. The fire danger index (FWI) reached 51, class Extreme.
- 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 25 April 2022 to 10 May 2022. 833 Suomi-NPP VIIRS detections on those dates.
- Compared with CONAFOR: 8,867 official ha against 11,347 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 2020, 100 m cells), summed inside the perimeter: an estimate of what was there, not a damage count.
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.
