Santo Domingo fire, May 2017 Santo Domingo, Villa de Cos, Mazapil
The fire started on 15 May 2017 in Santo Domingo, Mexico, and satellites saw it burning for 5 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 4,417 hectares from heat detections, spread across 3 municipalities.
It is the 8th largest in San Luis Potosí since 2016 (of 19 with a page). Number 85 in Mexico in 2017, of 374.

Fire radiative power detected each day, in megawatts, and number of hotspots. The magenta bar marks the peak day.
The weather it burned in
It had gone 0 days without rain (1 mm or more) when it started. Rain came after the fire: 1.5 mm on 23 May.
This area had burned before
No earlier perimeters overlap this fire since 2016, when the satellite record begins.

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 0.23 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.

Several official records match this area
According to CONAFOR, 2 fires started inside this perimeter on these dates, totalling 1,875 ha (the satellite measured 4,417 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.

- 2 Villa de Cos Rancho el Chorreado 16 May 2017 893 ha · extinguished on 20 May 2017 · cause: natural (lightning)
Total according to CONAFOR: 1,875 ha, 42 % of the 4,417 ha in the satellite perimeter.

The weather day by day
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.

Frequently asked questions
- How long did the Santo Domingo fire last?
- GWIS (Copernicus) dates it between 15 May 2017 and 19 May 2017: 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 4,417 hectares (44.2 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire entered 3 municipalities: Santo Domingo (2,434 ha, 0.6 %); Villa de Cos (1,132 ha, 0.2 %); Mazapil (874 ha, 0.1 %).
- What was the weather like?
- During the fire the temperature reached 28.7 °C, humidity dropped to 6 % and gusts hit 40 km/h. The fire danger index (FWI) reached 40, 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 from the perimeter: the VIIRS detections inside it did not change them. 202 Suomi-NPP VIIRS detections on those dates.
- Compared with CONAFOR: 1,875 official ha against 4,417 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.
