Dzilam de Bravo fire, September 2016
Dzilam de Bravo, San Felipe
Out · last detection 24 Sept 2016, 18:34 UTC
The fire started on 22 September 2016 in Dzilam de Bravo, Mexico, and satellites saw it burning for 3 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 2,043 hectares from heat detections, spread across 2 municipalities.
It is the 7th largest in Yucatán since 2016 (of 15 with a page). Number 118 in Mexico in 2016, of 204.

Satellites pass a few times a day and cloud or smoke can hide the fire: a lack of detections is not an official extinction. Each country’s emergency service declares a fire contained or out.

Fire radiative power (FRP) measures the energy the fire gives off when the satellite passes. Added up by day, it compares intensity, not area.

High of 33.5 °C and minimum humidity of 59% on 24 September 2016; gusts of 35 km/h on 22 September 2016.
These are model values for a cell of about 25 km, not from a weather station: they may differ from what was measured on the ground.

Nearby records with very different figures: 1,265 ha (records: 1).
A version keeps the area, dates, name and official record; the area as it was logged (changes under 2% are not logged). The map, hotspots and weather always show today’s data.

A lede of about 60 words figures only, no adjectives
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 2015
Built-up area< 0.1ha
Residents< 20
Inside the perimeter there was no noticeable 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.
According to CONAFOR, this fire started on 22 September 2016 and burned 1,265 ha (the satellite measured 2,043 ha). The two figures differ a lot, so these may not be exactly the same fire: take them as nearby records.

How a twin is chosen
Same area: fires that have already ended, less than 250 km from this one, since 2016.
Same start: we compare the FWI on the first day, the minimum humidity that day and the run of days without rain before it. The slider sets how much they may differ.
Only pages with final weather data (ERA5 reanalysis) calculated in the same way as this fire’s; agricultural and grass burns and pages with data under review are left out.
Fires burning at the same time as this one (a week before or after) are left out: they share the same spell of weather and do not count as a precedent.
They are sorted by similarity, and the outlines of the first five are drawn.
GWIS (Copernicus) dates it between 22 September 2016 and 24 September 2016: 3 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 2,043 hectares (20.4 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire entered 2 municipalities: Dzilam de Bravo (1,734 ha, 4.0 %); San Felipe (290 ha, 0.6 %).
What was the weather like?
During the fire the temperature reached 33.5 °C, humidity dropped to 59 % and gusts hit 35 km/h. The fire danger index (FWI) reached 6, class Low.
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.
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.
⚑Report an errorHow 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. 61 Suomi-NPP VIIRS detections on those dates.
Compared with CONAFOR: 1,265 official ha against 2,043 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.
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.
