Out · last detection 26 Oct 2023, 05:25 UTC

The fire started on 8 October 2023 in Huacaraje, Bolivia, and satellites saw it burning for 19 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 19,681 hectares from heat detections, spread across a single municipality.

It is the 54th largest in Beni since 2016 (of 903 with a page). Number 17 in Bolivia in 2023, of 248.

It had gone 0 days without rain (1 mm or more) when it started. Rain came after the fire: 2.5 mm on 27 Oct.

This area had burned before

100% of the perimeter overlaps earlier fires recorded since 2016: 9,802 ha in 2016, 4,453 ha in 2017, 4,168 ha in 2018, 2,664 ha in 2019, 13,359 ha in 2020, 13,543 ha in 2021, 14,527 ha in 2022. Part of it burned more than once, so the yearly figures add up to more than the 19,664 ha that had burned before.

How big is it?

10 km
It burned the equivalent of 12% of the area of London (197 km² against 1,583 km²).

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.

Inside the perimeter there was no noticeable built-up land and almost nobody lived there (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.

Frequently asked questions

How long did the Huacaraje fire last?
GWIS (Copernicus) dates it between 8 October 2023 and 26 October 2023: 19 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 19,681 hectares (196.8 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire only entered Huacaraje (19,802 ha, 3.6 %).
What was the weather like?
During the fire the temperature reached 38.8 °C, humidity dropped to 32 % and gusts hit 44 km/h. The fire danger index (FWI) reached 28, class High.
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.

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. 973 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.

How we build fire pages: methodology ›

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.
