Buachet fire, January 2019 บัวเชด · Thailand

Out · last measured on 19 Jan 2019

The fire started on 14 January 2019 in Buachet, Thailand, and satellites saw it burning for 6 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 1,136 hectares from heat detections, spread across a single municipality.

Number 363 in Thailand in 2019, of 463.

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 15 days without rain (1 mm or more) when it started.

This area had burned before

38% of the perimeter overlaps earlier fires recorded since 2016: 201 ha in 2017, 267 ha in 2018. Part of it burned more than once, so the yearly figures add up to more than the 436 ha that had burned before.

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 Buachet fire last?
GWIS (Copernicus) dates it between 14 January 2019 and 19 January 2019: 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 1,136 hectares (11.4 km²). It is an estimate: official national figures may differ.
What was the weather like?
During the fire the temperature reached 33.7 °C, humidity dropped to 39 % and gusts hit 43 km/h. The fire danger index (FWI) reached 23, class High.
Where does this data come from?
From the GWIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Thailand (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 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.
