Barito Selatan fire, August 2019 Barito Selatan, Kapuas

Out · last measured on 26 Sept 2019

The fire started on 31 August 2019 in Barito Selatan, Indonesia, and satellites saw it burning for 27 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 28,138 hectares from heat detections, spread across 2 municipalities.

It is the 17th largest in Central Kalimantan since 2016 (of 318 with a page). Number 4 in Indonesia in 2019, of 417.

We have the GWIS perimeter for this fire, but the VIIRS sensors did not capture it in enough detail: no day-by-day evolution, but the split by municipality is there.

It had gone 3 days without rain (1 mm or more) when it started. Rain came after the fire: 10.2 mm on 27 Sept.

This area had burned before

9% of the perimeter overlaps earlier fires recorded since 2016: 34 ha in 2017, 3,158 ha in 2018. Part of it burned more than once, so the yearly figures add up to more than the 2,571 ha that had burned before.

How big is it?

10 km
It burned the equivalent of 18% of the area of London (281 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

GHSL 2020
Built-up area1.1 ha
Residents≈ 200

Inside the perimeter there were about 1.1 hectares of built-up land and about 200 residents (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 Barito Selatan fire last?
GWIS (Copernicus) dates it between 31 August 2019 and 26 September 2019: 27 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 28,138 hectares (281.4 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire entered 2 municipalities: Barito Selatan (19,048 ha, 2.8 %); Kapuas (9,288 ha, 0.5 %).
What was the weather like?
During the fire the temperature reached 37.0 °C, humidity dropped to 29 % and gusts hit 38 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 Indonesia (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.

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 112.

How we know this
  • Perimeter: GWIS (Copernicus), rebuilt from heat detections rather than mapped on imagery; 4 polygons grouped in this page.
  • Dates from the perimeter: the VIIRS detections inside it did not change them. No 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 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.
