Reyes fire, August 2022 Reyes

Out · last detection 9 Sept 2022, 18:24 UTC

The fire started on 29 August 2022 in Reyes, Bolivia, and satellites saw it burning for 12 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 5,035 hectares from heat detections, spread across a single municipality.

It is the 431th largest in Beni since 2016 (of 902 with a page). Number 111 in Bolivia in 2022, of 222.

It had gone 10 days without rain (1 mm or more) when it started. Rain came after the fire: 1.6 mm on 13 Sept.

This area had burned before

55% of the perimeter overlaps earlier fires recorded since 2016: 1,411 ha in 2016, 3,034 ha in 2020. Part of it burned more than once, so the yearly figures add up to more than the 2,776 ha that had burned before.

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.

Frequently asked questions

How long did the Reyes fire last?
GWIS (Copernicus) dates it between 29 August 2022 and 9 September 2022: 12 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 5,035 hectares (50.4 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire only entered Reyes (5,081 ha, 0.4 %).
What was the weather like?
During the fire the temperature reached 34.7 °C, humidity dropped to 30 % and gusts hit 46 km/h. The fire danger index (FWI) reached 31, 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.

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.
