Villa Comaltitlán fire, April 2019 Villa Comaltitlán, Huixtla
The fire started on 23 April 2019 in Villa Comaltitlán, Mexico, and satellites saw it burning for 2 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 2,176 hectares from heat detections, spread across 2 municipalities.
It is the 129th largest in Chiapas since 2016 (of 265 with a page). Number 216 in Mexico in 2019, of 364.

Official record
According to CONAFOR, this fire started on 23 April 2019 and burned 801 ha (the satellite measured 2,176 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 Villa Comaltitlán fire last?
- GWIS (Copernicus) dates it between 23 April 2019 and 24 April 2019: 2 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 2,176 hectares (21.8 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire entered 2 municipalities: Villa Comaltitlán (1,841 ha, 4.1 %); Huixtla (347 ha, 0.9 %).
- What was the weather like?
- During the fire the temperature reached 35.9 °C, humidity dropped to 33 % and gusts hit 35 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 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.
Emergency number: 911

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 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.
