Fang fire, March 2022 Thailand

Out · last measured on 20 Mar 2022

The fire started on 18 March 2022 in Fang, Thailand, and satellites saw it burning for 3 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 1,262 hectares from heat detections, spread across a single municipality.

It is the 315th largest in Chiang Mai Province since 2016 (of 463 with a page). Number 31 in Thailand in 2022, of 58.

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 0 days without rain (1 mm or more) when it started. Rain came after the fire: 1.3 mm on 21 Mar.

This area had burned before

100% of the perimeter overlaps earlier fires recorded since 2016: 920 ha in 2016, 754 ha in 2017, 982 ha in 2018, 1,320 ha in 2019, 818 ha in 2020, 930 ha in 2021. Part of it burned more than once, so the yearly figures add up to more than the 1,268 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 Fang fire last?
GWIS (Copernicus) dates it between 18 March 2022 and 20 March 2022: 3 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 1,262 hectares (12.6 km²). It is an estimate: official national figures may differ.
What was the weather like?
During the fire the temperature reached 35.5 °C, humidity dropped to 33 % and gusts hit 26 km/h. The fire danger index (FWI) reached 16, class Moderate.
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.
