Reyes fire, 5 September 2022 Reyes

Out · last detection 9 Sept 2022, 18:25 UTC

The fire started on 5 September 2022 in Reyes, Bolivia, and satellites saw it burning for 5 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 11,510 hectares from heat detections, spread across a single municipality.

It is the 118th largest in Beni since 2016 (of 903 with a page). Number 38 in Bolivia in 2022, of 222.

It had gone 16 days without rain (1 mm or more) when it started. Rain came after the fire: 4.1 mm on 10 Sept.

This area had burned before

59% of the perimeter overlaps earlier fires recorded since 2016: 1,941 ha in 2016, 3,196 ha in 2017, 938 ha in 2018, 1,995 ha in 2019, 869 ha in 2020, 566 ha in 2021. Part of it burned more than once, so the yearly figures add up to more than the 6,761 ha that had burned before.

How big is it?

It burned the equivalent of 7.3% of the area of London (115 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.

People and buildings inside the perimeter

Built-up area< 0.1 ha
Residents< 20

Inside the perimeter there was no noticeable built-up land and almost nobody lived there (GHSL 2020, 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.

Frequently asked questions

How long did the Reyes fire last?
GWIS (Copernicus) dates it between 5 September 2022 and 9 September 2022: 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 11,510 hectares (115.1 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire only entered Reyes (11,557 ha, 1.0 %).
What was the weather like?
During the fire the temperature reached 36.2 °C, humidity dropped to 26 % and gusts hit 43 km/h. The fire danger index (FWI) reached 36, 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. 281 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 2020, 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.
