Coribe fire, September 2022 Coribe

Out · last detection 19 Sept 2022, 16:56 UTC

The fire started on 13 September 2022 in Coribe, Brazil, and satellites saw it burning for 7 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 3,537 hectares from heat detections, spread across a single municipality.

It is the 389th largest in Bahia since 2016 (of 466 with a page). Number 512 in Brazil in 2022, of 687.

It had gone more than two months without rain (1 mm or more) when it started. Rain came after the fire: 5.0 mm on 24 Sept.

This area had burned before

13% of the perimeter overlaps earlier fires recorded since 2016: 438 ha in 2020, 82 ha in 2021. Part of it burned more than once, so the yearly figures add up to more than the 476 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 Coribe fire last?
GWIS (Copernicus) dates it between 13 September 2022 and 19 September 2022: 7 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 3,537 hectares (35.4 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire only entered Coribe (3,561 ha, 1.3 %).
What was the weather like?
During the fire the temperature reached 37.0 °C, humidity dropped to 13 % and gusts hit 40 km/h. The fire danger index (FWI) reached 52, class Extreme.
Where does this data come from?
From the GWIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Brazil (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.

Emergency number: 193

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.

We will only use your email to reply about this report. Privacy. This is not an emergency service: if there is a fire now, call 193.

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 ADM2 (Creative Commons Attribution 3.0 Intergovernmental Organisations (CC BY 3.0 IGO)). 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.
