San Matías fire, 2 August 2024 San Matías, Puerto Suárez, El Carmen Rivero Tórrez
Out · last detection 9 Oct 2024, 04:41 UTC
The fire started on 2 August 2024 in San Matías, Bolivia, and satellites saw it burning for 69 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 378,054 hectares from heat detections, spread across 3 municipalities.
This page is probably a fire complex, not a single fire. GWIS merges into one perimeter the fires that touch over weeks, which in large burning seasons can join dozens of separate fires. The total area is reliable; the origin and dates refer to the whole complex.

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.

It had gone more than two months without rain (1 mm or more) when it started. Rain came after the fire: 1.3 mm on 14 Oct.
This area had burned before
35% of the perimeter overlaps earlier fires recorded since 2016: 13,015 ha in 2016, 6,029 ha in 2017, 2 ha in 2018, 41,442 ha in 2019, 53,069 ha in 2020, 42,325 ha in 2021, 3,805 ha in 2022, 3,505 ha in 2023. Part of it burned more than once, so the yearly figures add up to more than the 132,899 ha that had burned before.

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 2025Built-up area1.1 ha
Residents≈ 100
Inside the perimeter there were about 1.1 hectares of built-up land and about 100 residents (GHSL 2025, 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. The GHSL 2025 epoch is a projection made from 2020 and earlier data.

It was 39.8 times larger than the median of its twins and lasted 69 days, against 11 days.
None of its 21 twins burned more. The weather on the first day does not explain everything: the wind in the following days, the fuel and the firefighting also count. In 5 of 21, not even 1 mm fell in the ten days after the end: they went out without rain. In the rest, the first rainy day brought a median of 3.0 mm.

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.

Frequently asked questions
- How long did the San Matías fire last?
- GWIS (Copernicus) dates it between 2 August 2024 and 9 October 2024: 69 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 378,054 hectares (3,780.5 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire entered 3 municipalities: San Matías (348,253 ha, 13 %); Puerto Suárez (22,086 ha, 1.6 %); El Carmen Rivero Tórrez (18,179 ha, 1.7 %).
- What was the weather like?
- During the fire the temperature reached 41.4 °C, humidity dropped to 16 % and gusts hit 54 km/h. The fire danger index (FWI) reached 78, class Very extreme.
- Where does this data come from?
- From the GWIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Bolivia (geoBoundaries). It is not an official report.
- How did the fires that started in similar weather in this area end?
- Fires less than 250 km away that started since 2016 with a similar FWI, humidity and dry spell: 21. Their median duration was 11 days and their median area 9,496 ha; 48 % went past 10,000 ha. None of its 21 twins burned more. The weather on the first day does not explain everything: the wind in the following days, the fuel and the firefighting also count. In 5 of 21, not even 1 mm fell in the ten days after the end: they went out without rain. In the rest, the first rainy day brought a median of 3.0 mm.
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; 8 polygons grouped in this page.
- Dates from the perimeter: the VIIRS detections inside it did not change them. 49,816 Suomi-NPP VIIRS detections on those dates.
- We have not matched this page with any official record.
- 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 2025, 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 ADM3 (Public Domain). 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.
