Juchipila fire, May 2017 Juchipila, Teúl de González Ortega, Moyahua de Estrada
The fire started on 22 May 2017 in Juchipila, Mexico, and satellites saw it burning for 10 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 3,837 hectares from heat detections, spread across 4 municipalities.
It is the 12th largest in Zacatecas since 2016 (of 32 with a page). Number 104 in Mexico in 2017, of 374.

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 2015Inside the perimeter there were about 0.55 hectares of built-up land and almost nobody lived there (GHSL 2015, 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.

Official record
According to CONAFOR, this fire started on 22 May 2017 and burned 2,502 ha (the satellite measured 3,837 ha). The two figures differ a lot, so these may not be exactly the same fire: take them as nearby records.

Frequently asked questions
- How long did the Juchipila fire last?
- According to the heat detections seen by satellite inside the perimeter, it burned from 22 May 2017 to 31 May 2017 (10 days). The perimeter dates it from 22 May 2017 to 28 May 2017.
- How much area did it burn?
- The perimeter GWIS (Copernicus) rebuilt from heat detections is 3,837 hectares (38.4 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire entered 4 municipalities: Juchipila (3,383 ha, 10.0 %); Teúl de González Ortega (203 ha, 0.3 %); Moyahua de Estrada (189 ha, 0.4 %); Mezquital del Oro (82 ha, 0.2 %).
- What was the weather like?
- During the fire the temperature reached 30.5 °C, humidity dropped to 8 % and gusts hit 48 km/h. The fire danger index (FWI) reached 52, 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 22 May 2017 to 28 May 2017. 201 Suomi-NPP VIIRS detections on those dates.
- Compared with CONAFOR: 2,502 official ha against 3,837 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 2015, 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.
