Concepción fire, October 2021 Concepción
The fire started on 19 October 2021 in Concepción, Bolivia, and satellites saw it burning for 6 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 5,528 hectares from heat detections, spread across a single municipality.
It is the 404th largest in Santa Cruz since 2016 (of 834 with a page). Number 70 in Bolivia in 2021, of 155.

Where it burned
How it evolved, day by day
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: 2.8 mm on 28 Oct.
This area had burned before
80% of the perimeter overlaps earlier fires recorded since 2016: 97 ha in 2016, 407 ha in 2018, 4,657 ha in 2019. Part of it burned more than once, so the yearly figures add up to more than the 4,432 ha that had burned before.
What happened to each town
-
5,568 ha0.2 %
Burnt area inside each municipality, from crossing the GWIS perimeter with administrative boundaries. The distance is from the town centre to the nearest fire: staying a kilometre away does not mean it reached the houses.
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 Concepción fire last?
- GWIS (Copernicus) dates it between 19 October 2021 and 24 October 2021: 6 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 5,528 hectares (55.3 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire only entered Concepción (5,568 ha, 0.2 %).
- What was the weather like?
- During the fire the temperature reached 36.0 °C, humidity dropped to 32 % and gusts hit 74 km/h. The fire danger index (FWI) reached 27, 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.

Satellite cross-check
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 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.
